“A CPU that runs entirely on the GPU”

I imagine a carefully crafted set of programming primitives used to build up the abstraction of a CPU…

“Every ALU operation is a trained neural network.”

Oh… oh. Fun. Just not the type of “interesting” I was hoping for.

Get used to it. The modern day solution for everything right now is to throw AI at it.

Hmmm... I need to measure this piece of wood for cutting, let me take a picture of it and see what the ai says its measurement is instead of using a measuring tape because it is faster to use the AI.

Begin reimplementing a subleq/muxleq VM with GPU primitive commands:

https://github.com/howerj/muxleq (it has both, muxleq (multiplexed subleq, which is the same but mux'ing instructions being much faster) and subleq. As you can see the implementation it's trivial. Once it's compiled, you can run eforth, altough I run a tweked one with floats and some beter commands, edit muxleq.fth, set the float to 1 in that file with this example:

     1 constant opt.float
The same with the classic do..loop structure from Forth, which is not enabled by default, just the weird for..next one from EForth:

     1 constant opt.control
and recompile:

     ./muxleq ./muxleq.dec < muxleq.fth > new.dec
run:

       ./muxleq new.dec
Once you have a new.dec image, you can just use that from now on.

by anthk

The bit about multiplication being ~12x faster than addition is worth pausing on. In silicon, addition is the "easy" operation — but here the complexity hierarchy completely inverts. Makes sense once you think about it: multiplication decomposes into parallel byte-pair lookups (which neural nets handle trivially as table approximation), while addition has a sequential carry chain you can't fully parallelize away.

Funny enough, analog computing had the same inversion — a Gilbert cell does multiplication cheaply, while addition needs more complex summing circuits. Completely different path to the same result.

What I haven't seen discussed: if the whole CPU is neural nets, the execution pipeline is differentiable end-to-end. You could backprop through program execution. Useless for booting Linux, but potentially interesting for program synthesis — learning instruction sequences via gradient descent instead of search. Feels like that's the more promising research direction here than trying to make it fast.

A fun experiment but I wonder how many out there seriously think we could ever completely rid ourselves of the CPU. It seems to be a rising sentiment.

The cost of communicating information through space is dealt with in fundamentally different ways here. On the CPU it is addressed directly. The actual latency is minimized as much as possible, usually by predicting the future in various ways and keeping the spatial extent of each device (core complex) as small as possible. The GPU hides latency with massive parallelism. That's why we can put them across relatively slow networks and still see excellent performance.

Latency hiding cannot deal well in workloads that are branchy and serialized because you can only have one logical thread throughout. The CPU dominates this area because it doesn't cheat. It directly targets the objective. Making efficient, accurate control flow decisions tends to be more valuable than being able to process data in large volumes. It just happens that there are a few exceptions to this rule that are incredibly popular.

This sentiment is not a recent thing. Ever since GPGPU became a thing, there have been people who first hear about it, don't understand processor architectures and get excited about GPUs magically making everything faster.

I vividly recall a discussion with some management type back in 2011, who was gushing about getting PHP to run on the new Nvidia Teslas, how amazingly fast websites will be!

Similar discussions also spring up around FPGAs again and again.

The more recent change in sentiment is a different one: the "graphics" origin of GPUs seem to have been lost to history. I have met people (plural) in recent years who thought (surprisingly long into the conversation) that I mean stable diffusion when talking about rendering pictures on a GPU.

Nowadays, the 'G' in GPU probably stands for GPGPU.

The dream I think has always been heterogeneous computing. The closest here I think is probably apple with their multi-core cpus with different cores, and a gpu with unified memory. (someone with more knowledge of computer architecture could probably correct me here).

Have a CPU, GPU, FPGA, and other specific chips like Neural chips. All there with unified memory and somehow pipelining specific work loads to each chip optimally to be optimal.

I wasn't really aware people thought we would be running websites on GPUs.

by volemo

CPU and GPU have very different ways of scheduling instructions, requiring somehow different interfaces and programming models.. I'd hazard to say that a GPU and CPU with unified memory access (like the Apple's M series, and most mobile chips) is already such a consolidated system.

by nine_k

by amelius

Agreed. Much like “RISC is gonna replace everything” - it didn’t. Because the CPU makers incorporated lessons from RISC into their designs.

I can see the same happening to the CPU. It will just take on the appropriate functionality to keep all the compute in the same chip.

It’s gonna take awhile because Nvidia et al like their moats.

by jagged-chisel

3/4/2026 at 1:27:58 PM

CISC only survived because CPUs now dedicate a ton of silicon to decoding the CISC stream into RISC-y microcode. RISC CPUs can avoid this completely, but it turns out backwards compatibility was important to the market and the transistor cost of "instruction decode" just adds like +1 pipeline depth or something.

by StilesCrisis

3/4/2026 at 7:57:07 PM

> CISC only survived because CPUs now dedicate a ton of silicon to decoding the CISC stream into RISC-y microcode.

For Intel CPUs, this was somewhat true starting from the Pentium Pro (1995). The Pentium M (2004) introduced a technique called "micro-op fusion" that would bind multiple micro-ops together so you'd get combined micro-ops for things like "add a value from memory to a register". From that point onward, the Intel micro-ops got less and less RISCy until by Sandy Bridge (2011) they pretty much stopped resembling a RISC instruction set altogether. Other x86 implementations like K7/K8/K10 and Zen never had micro-ops that resembled RISC instructions.

In absolute terms, this is true. But in relative terms, you're talking less than 1% of the die area on a modern, heavily cached, heavily speculative, heavily predictive CPU.

So, an iGPU/APU? Those exist already. Regardless, the most GPU-like CPU architecture in common use today is probably SPARC, with its 8-way SMT. Add per-thread vector SIMD compute to something like that, and you end up with something that has broadly similar performance constraints to an iGPU.

How do you class systems like the PS5 that have an APU plugged into GDDR instead of regular RAM? The primary remaining issue is the limited memory capacity.

I wonder if we might see a system with GPU class HBM on the package in lieu of VRAM coupled with regular RAM on the board for the CPU portion?

by fc417fc802

3/4/2026 at 11:16:59 AM

I don’t think the remaining issue is memory capacity. CPUs are designed to handle nonlinear memory access and that is how all modern software targeting a CPU is written. GPUs are designed for linear memory access. These are fundamentally different access patterns the optimal solution is to have 2 distinct processing units

by chris_money202

3/4/2026 at 5:48:31 PM

GDDR has high bandwidth but limited capacity. Regular RAM is the opposite, leaving typical APUs memory bandwidth starved.

Both types of processor perform much better with linear access. Even for data in the CPU cache you get a noticable speedup.

The primary difference is that GPUs want large contiguous blocks of "threads" to do the same thing (because in reality they aren't actually independent threads).

by fc417fc802

3/4/2026 at 11:53:26 AM

If anything, GPUs combine large private per-compute unit private address spaces and a separate shared/global memory, which doesn't mesh very well with linear memory access, just high locality. You can kinda get to the same arrangement on CPU by pushing NUMA (Non-Uniform Memory: only the "global" memory is truly Unified on a GPU!) to the extreme, but that's quite uncommon. "Compute-in-memory" is a related idea that kind of points to the same constraint: you want to maximize spatial locality these days, because moving data in bulk is an expensive operation that burns power.

by zozbot234

3/4/2026 at 8:26:30 PM

people say this a lot, but with little technical justification.

gpus have had cache for a long time. cpus have had simd for a long time.

it's not even true that the cpu memory interface is somehow optimized for latency - it's got bursts, for instance, a large non-sequential and out-of-page latency, and has gotten wider over time.

mostly people are just comparing the wrong things. if you want to compare a mid-hi discrete gpu with a cpu, you can't use a desktop cpu. instead use a ~100-core server chip that also has 12x64b memory interface. similar chip area, power dissipation, cost.

not the same, of course, but recognizably similar.

none of the fundamental techniques or architecture differ. just that cpus normally try to optimize for legacy code, but gpus have never done much ISA-level back-compatibility.

by markhahn

3/4/2026 at 2:01:02 PM

I don't think we get rid of the CPU. But the relationship will be inverted. Instead of the CPU calling the GPU, it might be that the GPU becomes the central controller and builds programs and calls the CPU to execute tasks.

by spot5010

3/4/2026 at 6:30:44 PM

But... why?

How do you win moving your central controller from a 4GHz CPU to a multi-hundred-MHz single GPU core?

If we tried this, all we'd do is isolate a couple of cores in the GPU, let them run at some gigahertz, and then equip them with the additional operations they'd need to be good at coordinating tasks... or, in other words, put a CPU in the GPU.

by jerf

I think it's curious that you're saying "on GPU" when you mean "using tensors." GPUs run compute shaders naturally and can trivially act like CPUs, just use CUDA. This is more akin to "a CPU on NPU" and your NPU happens to be a GPU.

Hi! I think that the idea is certainly a fun one. There is a long history of trying to make a good parallel operating system. I do not think that any of the projects succeeded though. This article is a good read if you are interested in that. I am not sure why the economics of parallel computer operating systems have not worked out so far.

by nomercy400

3/4/2026 at 9:54:28 AM

To multiply two arbitrary numbers in a single cycle, you need to include dedicated hardware into your ALU, without it you have to combine several additions and logical shifts.

As to why not use the ADD/MUL capabilities of the GPU itself, I guess it wasn’t in the spirit of the challenge. ;)

I wish the project said how many CPUs could be run simultaneously on one GPU.

It might be worth having a CPU that's 100 times slower (25 MHz) if 1000 of them could be run simultaneously to potentially reach a 10 times speedup for embarrassingly parallel computation. But starting from a hole that's 625000x slower seems unlikely to lead to practical applications. Still a cool project though!

3/4/2026 at 7:14:00 AM

This CPU simulator does not attempt to achieve the maximum speed that could be obtained when simulating a CPU on a GPU.

For that a completely different approach would be needed, e.g. by implementing something akin to qemu, where each CPU instruction would be translated into a graphic shader program. On many older GPUs, it is impossible or difficult to launch a graphic program from inside a graphic program (instead of from the CPU), but where this is possible one could obtain a CPU emulation that would be many orders of magnitude faster than what is demonstrated here.

Instead of going for speed, the project demonstrates a simpler self-contained implementation based on the same kind of neural networks used for ML/AI, which might work even on an NPU, not only on a GPU.

Because it uses inappropriate hardware execution units, the speed is modest and the speed ratios between different kinds of instructions are weird, but nonetheless this is an impressive achievement, i.e. simulating the complete Aarch64 ISA with such means.

You could coalesce multiple instructions per shader, but even with a single CPU instruction (which would be translated to a sequence of GPU instructions), you could reach orders of magnitude greater speed than in this neural network implementation, by using the arithmetic-logic execution units of the GPU.

Once translated, the shader programs would be reused. All this could be inserted in qemu, where a CPU is emulated by generating for each instruction a short program that is compiled and then the resulting executable functions are cached and executed during the interpretation of the program for the emulated CPU.

In qemu, one could replace the native CPU compiler with a GPU compiler, either for CUDA or for a graphic shader language, depending on the target GPU. Then the compiled shaders could be loaded in the GPU memory, where, if the GPU is recent enough to support this feature, they could launch each other in execution.

Eventually, one might be able to use a modified qemu running on the CPU to bootstrap a qemu + a shader compiler that have been translated to run on the GPU, so that the entire simulation of a CPU is done on the GPU.

It's both. Being dirrctly a part of it makes it integrated into its intelligence for training and operation.

The computer ALREADY does do math reliably. You are missing the point.

That would be cool. A way to read cpu assembly bytecode and then think in it.

It's slower than real cpu code obviously but still crazy fast for 'thinking' about it. They wouldn't need to actually simulate an entire program in a never ending hot loop like a real computer. Just a few loops would explain a lot about a process and calculate a lot of precise information.

"Result: 100% accuracy on integer arithmetic" - Could someone with low-level LLM expertise comment on that: Is that future-proof, or does it have to be re-asserted with every rebuild of the neural building blocks? Can it be proven to remain correct? I assume there's a low-temperature setting that keeps it from getting too creative.

The creative thinking behind this project is truly mind boggling.

can i run linux on a nvidia card though?

iirc theres an app on the app store that's basically a small alpine container

Well, there's iSH and a-Shell but they don't have GUI capability and are somewhat limited in other ways. There's also UTM, but without weird hacks you can only get SE version which is very slow.

Well GPU are just special purpous CPU.

Ya know just today I was thinking around a way to compile a neural network down to assembly. Matching and replacing neural network structures with their closest machine code equivalent.

This is way cooler though! Instead of efficiently running a neural network on a CPU, I can inefficiently run my CPU on neural network! With the work being done to make more powerful GPUs and ASICs I bet in a few years I'll be able to run a 486 at 100MHz(!!) with power consumption just under a megawatt! The mind boggles at the sort of computations this will unlock!

Few more years and I'll even be able to realise the dream of self-hosting ChatGPT on my own neural network simulated CPU!
