Framework's 10G Ethernet module exposes USB-C's complexity

Well, this is about USB 3.2 Gen 2x2, which is a mess created by USB IF for good old, blue USB A connectors. Not USB-C complexity.

USB 3.2 Gen 2x2 is the very rarely supported 20Gb/s variant of USB 3, and making devices now that require that for full performance is a weird decision, with high-speed capable ports generally having wider support for either USB4 or Thunderbolt3+. I imagine the reason would be that some chip with an otherwise poor market fit got cheap...

Throwing this into the mix definitely doesn't improve the USB-C "what does this port support" conundrum, but this specific one predates USB-C and is not at all something you'd normally hit.

> Not USB-C complexity

3.2 Gen 2x2 (and the occasionally relevant 1x2 if you have a weak cable) are USB C only.

USB C ports and cables have 4 USB 3 "superspeed" lanes rather than two. When you use an A to C cable only one pair of those connects. The point of the "x2" modes is that they use the second pair of lanes that would otherwise go unused.

Except of course they don't always go unused. DisplayPort Alternate Mode sends DisplayPort over those two "unused" lanes getting you USB 3 data alongside a half speed DisplayPort connection. (or alternatively full speed DisplayPort on all four and only USB 2), and then of course Thunderbolt 3 and modern USB4/TBT4 use all four lanes and tunnel everything.

Thank you for answering a question I didn't know I had

Hmm, yes I was conflating a few things there.

However, I'd hold that this is an extension of the USB 3 mess that predates USB-C, even if the x2 mode specifically was a USB-C addition.

The important thing for people to know is that support for USB 3.2 Gen 2x2 is practically non-existent: TB3 came before as a well-established (but premium) solution, and USB4 just two years after to commoditize it. A complicated solution with mid-tier bandwidth and none of the flexibility didn't attract attention, so support is poor.

10 Gb/s Ethernet interfaces do not require 20 Gb/s USB ports for reaching maximum performance, they already reach that on 10 Gb/s USB ports, despite of what the writer of TFA believes.

The main application of 20 Gb/s USB ports is to connect external NVMe SSDs, when faster USB 4 or Thunderbolt ports and SSDs are not available.

For an external NVMe SSD on USB, a 20 Gb/s USB port will double the throughput, unlike for a 10 Gb/s Ethernet interface where any improvements are completely negligible.

I do not think that 20 Gb/s USB Type C ports are "very rarely supported". Every mini-PC or desktop motherboard that I have bought during the last 10 years had at least one such USB port.

Such ports appear to be rare only on laptops, because most laptops have very few USB ports.

While this may be theoretically (almost) possible, I’m quite sure this is absolutely not the case in practice.

For example see these benchmarks of one of the more recent USB to Ethernet chipsets [1], that can reach ~9.5 Gb/s on USB 3.2 Gen 2x2 but only between ~6.2 to ~7.3 on 3.2 Gen 2x1 laptops.

1. https://www.jeffgeerling.com/blog/2026/new-10-gbe-usb-adapte...

Edit: Haha, didn’t realise TFA was by the same author as these benchmarks but he’s done a lot of testing and benchmarking of these kind of devices over a long time, and it agrees with all the other benchmarking from other people I’ve seen too!

In Ethernet, "10 Gbps" refers to the actual Ethernet frame throughput. The raw physical coding rate is usually somewhere around 10.3125 Gbps to account for this.

In USB 3.2 Gen 2x1, the actual USB packet throughput is 9.697 Gbps and the "10 Gbps" refers to the raw encoding rate.

This difference means you are guaranteed to lose at least a few hundred Mbps off maximum performance. It's not really a practical concern, but it's not an error to say 10 Gb/s USB ports lack the bandwidth needed to support the maximum performance of a 10 Gbps USB Ethernet adapter.

Are you talking about USB 3.2 Gen 2x2 though? Because I've never seen any MiniPC with this port and as for motherboards, I checked my local retailer and only ~15% of currently sold ones have Gen 2x2 (mostly high-end ones).

Most of my mini-PCs have been Intel NUCs (or more recently an ASUS NUC). I also had some Gigabyte and Zotac mini-PCs and a few others from less well-known vendors. IIRC almost all had one such 20 Gb/s USB Type C port, unless they had one or two faster Thunderbolt ports.

With mini-PCs, I frequently use external SSDs, so I certainly used those ports at their full speed.

The only mini-PCs that I had in recent years without such a fast USB port were Arm-CPU based, as those are typically starved in fast peripheral interfaces in comparison with the Intel/AMD CPUs.

If you read carefully (emphasis mine):

> The main problem is USB-C's bandwidth complexity - especially when paired with the Realtek RTL8159 Ethernet controller, which requires USB 3.2 Gen 2x2 (20 Gbps) to get the full rated 10 Gbps speeds

Jeff's statement wasn't that 10 Gb/s Ethernet requires 2x2. It's that that requirement comes from a very specific controller.

by pdpi

Ethernet is duplex though. 20Gb/s is the max throughput a 10Gb NIC can achieve.

The first half is true, the second half is not. Remember overhead. You don't need 20GB/sec, but you need to take into account the USB overhead.

by burnte

6/26/2026 at 9:44:54 AM

What about overhead? Can you truly do 10Gb/s networking on a 10Gb/s USB port? Would having such NIC on a 20Gb/s USB port not result in higher speeds?

by retired

6/26/2026 at 10:13:08 AM

It uses 128b/132b encoding so 10Gb/s USB ≈ 9.69Gb/s you do then have USB framing overhead but it's probably around 2% on typical 1500B ethernet frames. So all in you are losing probably 5% or so to overhead.

I am of the opinion that 5Gbe is a much more sensible speed for a laptop adapter right now as it uses half the power and can obviously run full wack on 10Gb/s USB so you're looking at like 5Gbe vs ~9.4Gbe.

by matt-p

6/26/2026 at 12:12:52 PM

Stop insisting on Cat.6A (and related) copper cables for speeds beyond 1000BASE-T (maybe beyond 2.5G by now), just use dumb multi mode fiber it's way easier technology-wise and if you want power you can have that as well.

At distances where Cat.6A is even an option the demands on the fiber are very low. And it uses less power than the BASE-T PHY. The cable at least without integrated power is very thin as well, unless you can't respect it enough to not kink it, in which case you'd want a thicker one just to prevent you from being able to break the fiber.

by namibj

6/26/2026 at 6:36:40 PM

In fact, just to for single mode fiber. Looking on fs.com, single mode cables are slightly cheaper, and the optics (for 10G) are $30 to MMF's $25.

And you get much better future proofing with SMF. And if you do need a long fast run, SMF is what you want.

by BenjiWiebe

6/26/2026 at 9:23:31 PM

I kind of a agree, but it's not going to happen for a long long time. The practicalities are just a nightmare.

How do I power an access point with fiber? Ok we add an AC wall socket to the ceiling but now we need a 'brick' to convert to DC. How do I remotely hard reboot an access point if it were to crash?

Fiber termination requires a fusion splicer and a trained engineer, sharps box etc. The power socket needs an electrician. It's just such a nightmare in comparison, install is going to be more expensive, longer to fix faults, less flexible to move a socket etc

by matt-p

6/26/2026 at 12:13:26 PM

Both 10 Gb/s Ethernet and 10 Gb/s USB have bit data rates that are 3% lower than 10 Gb/s, due to encoding (64/66 bits for Ethernet, 128/132 bits for USB).

So the their maximum speed is approximately 9.7 Gb/s.

Then for Ethernet there is a protocol-dependent overhead, e.c. depending on whether TCP or UDP is used, and depending on whether standard packets or jumbo packets are used.

The TCP overhead can reach in the worst case up to close to another 3%, reducing the achievable TCP throughput to around 9.4 Gb/s.

The USB frames add some extra overhead, but it is normally not important in comparison with other factors that can reduce the throughput.

All that a 20 Gb/s USB port can do is to reduce the overhead of the USB frames, but that is a negligible improvement. Using jumbo Ethernet frames (which are 6 times bigger than standard frames), if both ends support them, is likely more useful for increasing the throughput, than using a 20 Gb/s USB port.

by adrian_b

6/26/2026 at 1:22:30 PM

10 Gig ethernet is 10GBps usable rate (before packet overhead). The line rates are higher to accommodate this. For 10GBase-R, it's typically 10.3125 GBps, with a 64/66 encoding. For 10GBase-T, it's 4 lanes with PAM-16 at 800 MBaud -> 12.8 Gbps raw.

Point of clarification since it isn’t clear from the title. This isn’t a Framework product, but a product by Wisdpi designed for the Framework Expansion Card form factor.

Very cool to see an ecosystem developing around that form factor. Like the old PCMCIA, except not awful.

by trollbridge

6/26/2026 at 2:17:41 PM

I do wish there were something like Oculink, but with power available over the connector. USB-C does almost everything, but it seems the chips to break out PCIe lanes for USB4/Thunderbolt for higher speed devices are still a significant cost for accessories.

by NeckBeardPrince

6/26/2026 at 8:12:09 AM

hey Nirav, dumb question: would it be possible to have usb-c ethernet adapters using intel chips in order to have vPro features on framework laptops (along with vpro-enabled intel chips) ?

That's probably the missing cherry on top, as having vpro once the framework motherboard gets reused as a home server it gives some manageability features.

by znpy

6/26/2026 at 2:39:58 PM

vPro requires the NIC to be connected directly to the PCH (over PCIe/CNV). This is going over USB, which won't cut it.

An Intel WLAN card in an M.2 slot on the mainboard might work (given your givens; a vPro enabled chipset).

> vPro requires the NIC to be connected directly to the PCH (over PCIe/CNV). This is going over USB, which won't cut it.

i see, i did not know about this.

however, let me use your knowledge and ask you another question: vpro-enabled thinkpads without an ethernet port do have a dongle that should allow vpro-usage.

is that some kind of vpro-specific dongle? i mean, iirc that dongle also has to be connected to a very specific port

by znpy

6/26/2026 at 6:01:36 AM

I chuckled at 10G wired ethernet on a laptop. I mean in a docking station? Sure that seems reasonable. But fun none the less.

I appreciate the USB-C nature of the Framework's expansion ports, it does make real the entire reason that USB was created in the first place, hot plug slots. Still, I (and others) pointed out to Intel early on that using Ethernet with a specific packet type would be cheaper and just as fast (which the ATA over Ethernet folks proved), but then you wouldn't get the 'certification tax' that the USB consortium extracts. :-).

Cynicism aside, the design issues suggest that it might make sense in future laptops to have heat spreaders around the plug in port, although that makes things thicker and people obsess over thinness.

What difference does a docking station make? Sometimes you want to spend a minute or two setting up your laptop in a more serious way, and that's just as reasonable with or without a docking station.

by Dylan16807

6/26/2026 at 2:04:18 PM

The "dock" comment made sense to me because I don't think that true "road warrior" laptop use and 10G Ethernet deployments would coincide all that often.

I've put a disproportionate number of hours and $$$ into my homelab over the years, and I still only have 2.5G Ethernet switches deployed. Most offices' (much less home/coworking space/etc.) network traffic is passing through single-gigabit switches.

by rcoder

6/26/2026 at 6:28:06 PM

This is where my head is on docks. When your connected to enhanced infrastructure (like your home lab) sure, but when you're checked into the Embassy Suites? Not particularly useful :-).

That said, I'm kind of sad that Framework and others have generally opted to let "third party USB-C docks" be the docking solution. I miss the days when my Thinkpad dropped onto its docking station with a purpose build bottom connector and seamlessly became a desktop/deskside type computer that was wired into my desk setup. Sadly I think that vision of docking died with the Thinkpad's sale to Lenovo.

by ChuckMcM

6/26/2026 at 4:55:05 PM

I have a 5gbps symmetrical fiber connection at home, so I've spent a fair amount of time and money upgrading my homelab backbone to 10gbps. That includes a 10GBe connection to my desk, but I've had issues getting the connection to be reliable (terminating the shielded Cat6A I have in the walls is a pain). That drop hasn't been working for the past few months, so I've been on wifi instead; it hasn't been enough of an issue for me to invest the time in fixing it.

by organsnyder

6/26/2026 at 11:22:53 PM

With the rise of USB-C, docking-station-like devices are cheaper than ever before.

For $20 you can get something that will pass through power from a USB-C charger, 4k HDMI to a monitor, and provide gigabit ethernet and some USB ports. We're no longer in the bad old days of USB 2 where USB ethernet was noticeably slower - or of $$$ vendor-specific, laptop-specific docking stations.

And if you don't have a dedicated desk where you can set up your docking station, you're probably not going to enjoy the wired ethernet experience, because without a desk you'll have to crawl around to plug your ethernet cable into a floor port every time you move desks.

I still have a soft spot for laptops with built in ethernet ports, though, for connecting to devices in the field.

Back in the early days of wireless networking I had my laptop configured with the wireless and wired networks bonded. I want to say that was 2Mbps on the wireless, so if I was doing a big transfer I could walk over to a wired port in my house and plug in to get 100Mbps.

Others comments already mentioned multimedia, but for example where I work we have some development board and prototypes with 10g ethernet, but most developers have a laptop rather than a fixed station. Turns out smallish (but overly expensive) thunderbolt 10g adapters can be used for testing and even reach full thoughput in many cases.

by anthonj

6/26/2026 at 5:26:37 PM

The problem with docking stations is they're more expensive than an ethernet adapter. I tried to use a few 2.5+Gbps dongles with my laptop(s) to avoid spending $400 on another Caldigit dock (TS4; I already have a TS3 with 1Gbps ethernet).

Unfortunately, all 3 USB-C dongles I tried had significantly worse performance than the built-in 1 gig ethernet on the dock, apparently using the RTL8156 chipset which is known to be unstable.

I've got a 4th dongle on the way to try next! If I buy enough of these things I'll have spent more than just buying the right dock in the first place.

by rconti

6/26/2026 at 7:13:21 AM

If you work with media having a 10G connection on a laptop isn't all that absurd. In fact slow network speeds are the main reason why people have to use things like Thunderbolt instead of using a NAS (e.g. offloading data on a film set).

Future proofing. Websites nowadays load tens of megabytes for a simple news page. I wouldn’t be surprised if in the future a website consumes 500+ megabytes on the initial page load. That will take 40 seconds on a 100 megabit link and 400 milliseconds on a 10 gigabit link.

Try to load any modern website on dial-up. The connection will likely timeout before a full page load.

Fr. There was that small window back in the early ‘10s where data was slow and expensive in India and 4g wasn’t yet pervasive in China. Execs were still receptive to my pitches that we needed to spend some engineering cycles on rework to improve initial load times / weight after showing them simulations of absurdly slow first paint / first content over simulated 2g/3g from India / China data centers.

Once 5g became pervasive and data cheap, no one gaf about a cold load weight fitting on a floppy.

I’m still clutching my iphone mini, which after ios 26 just boggs down under the absurd weight of many pages and turns in to a space heater before reloading entire page b/c of error. No need for forced obsolescence when the enshittification of basic websites takes care of that for you. :-/

My laptop is basically a desktop in a clamshell so I don't need a docking station (and it's like 5 lbs with crazy cooling so I can use it as, you know, a laptop). I work with large binaries (media) on a daily basis. I have a 1G ethernet port built in, but I'd love a 10G port. I'd absolutely make use of it (maybe not all 10Gs of it, but most of them). Besides, things are only going to get faster...

by stronglikedan

6/26/2026 at 4:58:01 PM

I have a Thunderbolt 10Gbe adapter. It's a larger form factor than a Framework expansion card and it has a metal case, so it dissipates heat well. Copper 10Gbe chipsets generate a lot of heat.

by organsnyder

6/26/2026 at 2:04:51 AM

Every PCIe 10G ethernet card I've seen has a heatsink on it, sometimes covering the entire card or even have little fans on the heatsink.

Expecting it to work full time in a laptop is a bit of a stretch of the heat dissipation budget.

Also, the laptop he is working has the AMD FP8 chipset - depending on how the ports are setup, he might only get 10G USB, if the ports are allocated to video instead.

4W is TDP for some of Pi-style mini computers. Lots of them have fans.

by numpad0

6/26/2026 at 4:33:16 AM

Pi 4 and 5 both idle around 3W. But a Pi 5 can pull up to 16W with a USB peripheral, full CPU load, and decoding 4k video. The Pi 4 / 5 will run OKish without a heatsink at idle wattages, but thermal throttle quickly if you attempt to do something intensive.

These realtek 10gbe chips are more in the range of the Pi Zero class machines (0.5W idle, 2W loaded) which don't often come with heatsinks though they might benefit from them. If it has a good thermal connection to a good thick ground plane on the PCB, that's worth almost as much as a passive heatsink on the top of the chip.

usb-c < card edge < motherboard integrated in terms of how much heat can be transfered through the connection. Where the motherboard would have the largest ground plane to soak up heat from such an IC and dissipate it passively. The usb-c module is worst case by being a small enclosed box with very little thermal connection through the plastic insulating housing. An aluminum enclosure might dissipate enough heat passively to make it pleasant to use.

Especially on the Pi 5, which has no hardware encoder to save on power consumption for that task. It's entirely in the CPU.

Raspberry Pi 4 doesn't need a fan. People just like to put them on because because micromanaging CPU temperature is part of the hobby for some. Yes it might throttle its CPU speed when going full tilt for some time, but lets be real how many workloads require poor Raspberry Pi to be loaded 100% for prolonged periods of time?

by merpkz

If it throttles CPU it means by definition means that a fan helps. Also constant heat increases failure rate.

From what I've gathered, heat absolutely does[1] affect[2] it[3]:

Subsequently, in 1967, Black of Motorola experimentally derived a median time to failure (MTTF, i.e., operational lifetime) model for EM in Al interconnects, showing that the time to failure due to EM is inversely proportional to both the current density and the absolute temperature of the interconnect.

Yes, except that most devices use Ethernet. So, at the end of the day, you still need Ethernet cables unless you want to deal with an additional switch or converter in every room.

Fiber/10Gbase-*R is Ethernet too. Please say copper/RJ45/base-T when you mean copper/RJ45/base-T.

by eqvinox

6/26/2026 at 12:12:26 PM

If you want to ackshually, both fiber and copper are empty pipes that can carry any layer 2 protocol, and are not inherently Ethernet. They only become Ethernet cables when they're connected to terminals that pass that protocol through them.

Unless we're defining some networking standard, "Ethernet cable" is a perfectly acceptable term. Everyone will understand what is meant. The added specificity you're asking for doesn't improve the quality of communication.

by fluoridation

6/26/2026 at 12:13:19 PM

That's why I added base-*R/base-T.

And particularly for 10GE the heat and power problems are due to the copper transceiver DSPs.

And people nerdy enough to run 10GE at home might well run fibre.

So, no, the specifity is needed and useful.

6/26/2026 at 12:27:23 PM

>That's why I added base-*R/base-T.

You're still talking about a cable. The cable may be compatible with those standards, but you can put anything through it. It's just a physical connection.

>And people nerdy enough to run 10GE at home might well run fibre. So, no, the specifity is needed and useful.

No, because if you say "which do you want? Ethernet or fiber?" no one will look at you like if you asked if they want salt or beef. It's technically incorrect, but everyone will understand what is being asked.

> You're still talking about a cable. The cable may be compatible with those standards, but you can put anything through it. It's just a physical connection.

If you want to ackshually, the post I was replying to was talking about what "devices use" and cables required for that, so it's in fact about what standards these devices support.

Apart from that, again, in the context of 10GE you can by no means assume copper when talking about an Ethernet port; SFP+ slots are quite common. Your assertion that "everyone will understand" is also something I plainly know to be untrue in my bubble. It may be true in the context of slower speeds, but for ≥10GE the general performance characteristics of twisted-pair copper transceivers are so bad as to make it into the crossover point from copper cabling into DAC cables and fibre.

And, honestly, the assumption that "Ethernet = copper cabling" is harmful for 10GE. Those transceivers are hot garbage in the literal sense, they run hot enough to warrant usage limitations on switches due to cooling/overheating limits, and they tend to be quite picky about cable quality on establishing links.

6/26/2026 at 6:01:05 PM

>the post I was replying to was talking about what "devices use" and cables required for that

Yes, that person said "most devices use Ethernet", to which you correctly pointed out they meant to say RJ45. However, in the process of making that correction you made an unrelated error yourself in saying that fiber is Ethernet too.

>you can by no means assume copper when talking about an Ethernet port

You can, if by "Ethernet" you mean an RJ45 jack and its cable, which is a fairly common usage of the word. It doesn't matter that it's technically incorrect. The default idea of physical protocol that the word "Ethernet" invokes in most people is that of twisted pair copper cabling. If you take a random person and put in front of them a fiber optic cable carrying Ethernet and a copper cable carrying serial signals and tell them "would you mind unplugging the Ethernet cable?" they'll disconnect the copper cable.

>Your assertion that "everyone will understand" is also something I plainly know to be untrue in my bubble.

Oh, so you know several people who when presented with the dichotomy of Ethernet or fiber (because that's what the comment you replied to was about, as it put Ethernet in contrast with fiber), they'll be completely dumbfounded about what is meant, as if hearing gobbledygook?

Indeed, that's largely why I decided 10gbit at home isn't really worth it. The current 10gbit ethernet stuff is expensive and power hungry, the enterprise stuff is hard to use on consumer gear. And the only real use case is super fast access to a nas.

by Gigachad

6/26/2026 at 6:14:24 AM

I got it solely because our ISP bumped our home fiber to 10Gb and it would’ve hurt my soul for the router to be slower than that. And hey, if you’ve already got a router with 10Gb ports available and ready to go…

by kstrauser

6/26/2026 at 7:03:21 AM

> every room

I disagree with that for two reasons. First, my central switch is probably capable of both copper and fiber. Second, how many wired devices do you have spread around your house? Let's say I have an above average number of devices: a router, a NAS, two access points, and three desktops. Router, NAS, and one access point can all be adjacent to the switch and avoid any conversion hassle. The desktops are using fiber so no conversion hassle there. That leaves one copper cable or converter needed for the other access point.

by Dylan16807

6/26/2026 at 11:14:53 AM

I guess I have rather overestimated what a normal amount of wired devices is based on my own sample size. That or the opposite is happening with you.

My house has a POE doorbell, several POE cameras, 2 TVs that each get a connection to their attached android TV boxes, Wife's office gets a pair of connections, ditto with mine, then you've got the APs for the wireless bits + a few servers in the rack with the networking equipment.

Mind you I know I am on the high side, but I use that as the reference point. I'd figure a normal house would have 4-5 wired connections to my 20ish.

by krisroadruck

6/26/2026 at 5:07:52 PM

In that situation I'd basically consider the doorbell and cameras as a separate install.

That mainly leaves the TVs, which I would just throw on the wireless but for wiring I'd still say you run it to your central switching spot that handles both copper and fiber.

It's hard to justify when Ethernet is catching up. Most new motherboards have a 2.5G port. High-end motherboards have 10G Ethernet ports. SFP cards take space, are ugly, and need directed airflow to stay cool. They are not worth it for a 4x increase in bandwidth at best.

Fibre requires conduit with specific radius bends, making it difficult to route through a house.

by bjt12345

6/26/2026 at 3:14:05 PM

Having cabled my apartment with Cat 6 definitely made me prefer fiber, it would have been a breeze instead of pulling thick cables from my office to other rooms. Cat 6 also shouldn’t be bent or you risk it going out of spec, and modern fiber nowadays have bend radius comparable to (or even smaller than) Cat 6.

I see how sloppy some FTTH installs are and they all work fine, and this is for light that travels for long distances.

The only advantage copper has is PoE.

by rescbr

6/26/2026 at 2:20:06 PM

You'd be amazed what exists on the market these days. For example, the pre-terminated InvisiLight fiber cabling is 0.6mm in diameter and has a 2.5mm bend radius. I've personally installed this cabling while making many 90 degree (and sharper in some cases) bends without any issues. That makes it easy to hide and trivial to fit right through doorways and other tight spaces too.

I mean sure, I could install a sfp+ card, but the cat5 installed in 2003 or so works fine with my 10gbase-T equipment (maybe it won't work on all my runs, but so far I'm two for two and I ran out of 10g ports on my core switch). Why would I tear up my walls to run fiber when I have cabling that works for me. (I use dac for servers near the switches)

I have seen some attractively priced 40g equipment on ebay, but honestly 1G wasn't really limiting me, I just wanted to see if 10g would work.

Unlike "5 Gb/s" USB, which in reality is 4 Gb/s USB, so a 5 Gb/s Ethernet interface cannot reach its maximum speed on a 5 Gb/s USB, the "10 Gb/s" USB is really 10 Gb/s, i.e. the difference between its real speed and 10 Gb/s is small enough to be negligible.

The same is true for 10 Gb/s Ethernet, whose speed is not exactly 10 Gb/s, but the difference from 10 Gb/s is also negligible.

Therefore, you do not need a 20 Gb/s USB to reach the maximum speed with a 10 Gb/s Ethernet interface, a 10 Gb/s USB port is good enough.

The overhead of data framing on USB is slightly higher than on Ethernet, so the maximum throughput on an USB 10 Gb/s Ethernet interface is a little lower than for a PCIe Ethernet NIC, but the difference is small enough to not matter. Usually other factors, like bad device drivers or inefficient programs, can cause much greater variations in Ethernet throughput.

The 9.4 Gb/s throughput obtained in TFA is perfectly reasonable when taking into account the packet overheads, which make impossible to reach 10 Gb/s for user data, regardless of hardware. A 20 Gb/s USB interface could not provide any serious improvement over that.

by adrian_b

6/26/2026 at 8:13:28 AM

Before Jeff first talk about this, I got one of those cheap Ethernet adapters (with the new realtek chip) on aliexpress for ~55€. It works really well, but I don't have USB 3.2 Gen 2x2 hardware, so I only get ~4Gbps out of it. But I'm pretty happy to break the 1G barrier, and the adapter will be useful in the future when I get better hardware; and I don't have to go through a 2.5Gbps or 5Gbps step.

by Aissen

6/26/2026 at 1:57:30 AM

In a way, I kinda don't get the idea of an expansion card for ethernet, rather than just a dongle. Specifically, as in this case, where it sticks out from the side of the chassis.

If I'm on the go, I'll have to take it out of the chassis while it's in my bag so I don't damage it. In that case, it's easier to have a regular USB-C card in that port, and toss a dongle in my bag instead of the expansion card.

If I'm not on the go, I'm at a desk, and I'd still rather plug in a dongle than regularly swap an expansion card.

I'm not saying you'd never want the expansion card, but it feels pretty niche.

In that case I'd rather just have one of those big usb hubs that has every port on it. Rather than an adapter designed that it only works on one laptop. Sure in theory you could plug them in to any but the design of it is such that you'd snap the connector if you plugged it in to a normal port.

While a regular usb-c ethernet adapter has a flexible cable between the laptop and the bulky rigid part.

by Gigachad

6/26/2026 at 3:09:36 AM

Thunderbolt hubs are rather amazing now; in the past they'd either get super hot and have reliability issues, or had severe bandwidth limitations (especially if using larger displays).

The current crop has been great for my needs — a couple models have 10G Ethernet built in (CalDigit is the one I'm using now), and most now have more than one Thunderbolt port that allows a high speed storage device to be used as well (in addition to a 5K or 4K display or two!).

The minis, despite being sold at the same time as SEs and having to share demand, did fine. And if you want to improve that situation the obvious answer is to pick one or the other, not to cancel both. If you want even better stats, much more than needed, wait 2-3 years between releases.

My best guess for Apple's actions is that despite there being a very real demand for a smaller phone, they don't think the discomfort is bad enough for people to switch to Android, so they don't even try. A small phone makes a lot of profit, but ignoring the demand also makes a lot of profit.

The Air was a real flop.

There’s nothing to “get”. The circuit doesn’t fit inside the slot for expansion cards. You could plug in a dongle instead, but then you’d have a big hole in your laptop with a cable sticking out. Or you could just get a wider laptop bag. They make them in multiple sizes, you know.

I view the temperature issue almost entirely as a copper problem. Every interface where you use CATx cables will have this issue; It's always extremely hot.

I believe at some point someone in the community was trying to design one of those slim ethernet ports that expands open when you need it (the jack doesn't really fit). Apparently some of the mechanisms for doing so are still proprietary though.

And that's when it's a legitimate Realtek chip. Many years ago, I bought a 100M Realtek Ethernet card, expecting it to work out of the box on Linux; but it was actually a counterfeit, using a Silan chip instead of a Realtek chip, and the out-of-tree Linux driver (for Linux 2.4) that came with it on the CD was actually a driver for the Silan chip with the numbers filed off. I ended up writing and submitting a Linux 2.6 driver for it, just to make people stop blaming the Realtek driver for not working with the unrelated Silan chip.

I think most people do not have 10g UTP infrastructure they want to exploit, but many people do have 2 computers they'd like to connect together at high speed, and these people are far better served by just connecting those computers' Thunderbolt ports together. With nothing other than an admittedly pricey cable, you get 10, 20, or 40gbps links depending on the endpoints. That's the "something faster" that will work well for most people.

Only Framework could reincarnate godawful PCMCIA cards as proprietary USB-C dongles and be praised for it. Insanity. Maybe next they can bring back the XJACK.

No one wants to address the elephant in the room: it's a crap design for proprietary modules. Sure the design is open, can you use them anywhere else? Nope.

You're paying a premium for USB-C dongles that can't be used on any other brand of laptop. Apple is probably upset they didn't think of it first.

by naturalmovement

6/26/2026 at 6:01:11 AM

Of course you can use the modules on any other brand of laptop. It's not going to look pretty doing it, but I've routinely used the USB-C to USB-A, as well as the mini SSD, on a MacBook Pro.

Colleagues borrow them all the time when they need a SD card or MicroSD card reader. Is it as pretty as a dedicated reader for those cards? No, but it does the job.

Saying they're proprietary is misleading a bit. The form factor makes it awkward to use elsewhere but they work just fine anywhere you plug them into.

by Patryk27

I knew someone would ask this.

It is mechanically disagreeable.

The weight/shape of the module will break the USB-C port in short order because it is solely supported by the connector.

For instance, by bumping the spatula hanging off your Mac.

For that matter, USB-C are crap connectors, I don't care how many graphs and BS data you show me stating they're the most reliable connector ever. I do not believe it.

They're the only types of connectors I've seen damaged repeatedly, and the only one with which I've personally experienced damage, and I've been using laptops since before many of you were born.

I have a 10GbE network in my house and a Framework 13 AMD laptop (7840U variant), I found that most of the available 10GbE adapters on the market get too hot, and after trying a few I settled on the UniFi USB4 10GbE adapter as it has enough thermal dissipation to be able to sustain full performance over an extended period of time. I don't see how you can dissipate enough heat in the Framework insert shells.

I'm not sure why you want to either really. I can't see many scenarios where the absolute portability of having a 10GBE adapter in the laptop is really necessary. I suspect the general use of these kind of things is for people docked at a desk, at which point its best served by a well cooled dongle or a chunky dock like a TS5

My use case is definitely while sitting at a desk in my home office where I can directly cable to my 10GbE switch. For other usage, I just stick to WiFi 7, which is usually plenty fast enough for most usage. I prefer connecting wired when doing downloads (Steam, OS upgrades, et al).

Same principle here - 2.5GBE dock on the desk, and UniFi WiFi 7 everywhere else. Though switching to the WiFi 7, which hits 1gb+ just about everywhere in the house, I generally feel less inclination to hit the desk

Sounds like the dual problem of "I want the thinnest" is the "I want the most powerful" on miniature equipment, and of course you run into an unbalanced situation

Honestly I don't see much of an use for 10Gbps in a notebook that can't be solved by a dongle when you actually need it

Does a laptop really need more than 1Gbps or whatever you can get through WiFi? It's an edge device not a router.

Well, it's Framework we are talking about. My plan is to buy it because at some point of its lifecycle my Framework 12 motherboard will be used as a new node in my Homelab. :)

Obviously not. I've got a $300 WQHD monitor that has 1GB/s over USB-C with power delivery. MacBooks have 2GB/s WiFi.

For the niche enthusiast, that dongle is fine.

No one needs anything, but can and do I use more than 1Gbps from my laptop? Of course. 1Gbps is only ~125MB/sec transfer speed. When I’m copying large files to and from my home NAS, I often want more speed than that so a while ago I picked up a 2.5g adapter, later 5g, and now finally with these new chips a 10g adapter.

Same for my SFF PC which only came with 2.5g onboard and no extra slots because ITX and can now do 10g via the same USB adapter which is great.

I agree, but laptops are severely power and storage limited. How many >100GB games or whatever can you really download and actually play on a typical laptop? If faster Ethernet increases power consumption, it's probably a negative overall.

Every laptop probably doesn’t, some laptops probably do.

Yes, I have 5Gbit symmetric fiber, why would I want to limit myself to less speed than that on my laptop? I regularly peak out my Internet connection while doing Steam downloads and OS updates.

Yours is an “edge device” but I am root, so mine is a portable tool for managing and testing the network that does not have working WiFi access points attached to it or obviously I would not be there.

And yes, some of those links are above 1gbps so that the users can have individual 1gbps links.

More amazed by the complexity in bundling offers, of decking out your Framework device with 6 flush USB-C port extension ports sets you back 60 bucks already.

That's like a weird hidden tax.

In a network world where 1GB Ethernet randomly can handshake at 100Mbit still, getting reliably more than 3/4 of the advertised Bandwith from the Adapter seems quite harmless.

No they dont come free in the base config either, you have to pay a minimum of 10 for every slush port.

I like the modularity, but I'd feel better if it came with the "blanks" that just extends the inside USB-C port towards the outside.

I feel like things would not look like nickel-and-diming if those blanks came with the laptop, and they just priced them in the final price. Or even better, offered the option to "upgrade" one or several of those to whatever you need.

I agree, but maybe not all slots need to be filled with blanks, maybe leaving one or two truly empty slots is OK.

Framework’s single greatest marketing triumph is selling a $20 3.5 mm audio jack for a device that doesn’t have one but easily could (Framework 16) and somehow avoiding constant complaints/“so brave”/etc.

Aside from me just now, I guess :p

Looks like it doesn't handle high impedance headphones well either. Oof.
