Anyone is using 64 cores besides Linus :) I'm much more excited for 7900x on 12 cores rather than 64 cores. But I understand the limited amount of people that needs this power on desktop can also be excited.

But then if 64 is not useful to you, why the 7900X instead of the 7700X and it's 8 cores? The 7700X is way less power hungry and boosts to nearly the same speed as the 7900X.

Genuinely asking as I plan to replace my Ryzen 3700X with a 7700X.

Can I use it in a base of my kettle to boil water?

the cpu is certified by AMD to be running up to 105 celsius, but it thermal throttles automatically at 95 celsius, so out of the box probably not enough to boil water, but just barely :P.

the fun fact, is that if you manually reduce the power limit to 65W the initial single thread results so virtually no loss in ST performance vs 170W, and it appears that the original AMD slides stating 75% more efficient cores at that level not too far off.

I recently ran some machine learning benchmarks on CPU versus GPU. The gap for a multicore CPU was much smaller than I expected. I, for one, am excited by a 64-core CPU in a way I wouldn't have been a year ago.

Between Hugging Face, Stable Diffusion, and Whisper, I'm using ML workloads a lot more. Being able to do so:

* with a standard instruction set

* with open-source software

* with my full system RAM

* without having to worry about what is in VRAM versus main RAM

is a big step up. I see about a 10x speed difference between an older 16-core CPU and a hot-off-the-press high-end Ampere card costing 3x as much as the CPU. If 64 core could bring that within 2x, or even 4x, I'd dump the GPU entirely.

Inference or training? I think with full training you are out of luck with CPUs, the gap is much bigger. 64c TR could only get to roughly 1TFlops.

You might want to wait for 7900X3D based on what we see with 5800X3D vs the latest Zen4...

Note that anyone trying to boil a kettle with a 170 W heater would be waiting around for 10s of minutes.

Eh?

My 5950x (measured) flops are ~2 TFLOPS in single-precision, ~1TFLOPS in double precision (obviously, due to half the SIMD vector size). This is a desktop-class 16-core machine.
