Apple M1 Ultra - is this enough for chess?

It should have more than enough power.

I knew it wouldn't take long to see something on the M1 ultra.

The issue is for media-related work its performance may be high (Geekbench suggests close to Threadripper 3990, but I think it overrates ARM related CPUs) but for chess it'll be lower for sure.

Secondly, you'd have to compile SF Dev yourself.

Thirdly, the choice of UIs is much lower on MACOS.

But I suppose if there's interest people could start developing engines / UIs for MACOS now.

Koivisto has support for ARM (M1) CPUs. I tested the performance compared to my 3950x and the speed is very similar.

Which M1 did you test?

M1, M1 Max etc?

For stockfish 14.1 pure nnue we should expect about 30MNps, extrapolating from https://forums.macrumors.com/threads/st ... 0.2326552/ and https://browser.geekbench.com/v5/cpu/co ... e=13330272. Comparing to http://ipmanchess.yolasite.com/amd--int ... ckfish.php it should place around AMD Ryzen 9 3900X/ Intel Core i5 12600K. Respectable, but nothing special.

Write code to make Stockfish use more of the power/potential from the M1 Ultra.

Here is one gold nugget on the M1 ARM:

You get the innocent looking instruction __rbitll
Its the bitreverse (not byte) instruction!

That makes it possible to have a uniform hyperbola quiescence algorithm like implemented in this thread:

What will also be interesting is the gpu performance - since Vulcan CRUSHES any CPU.

I already did. Performance on M1 is close to the limit.

You can get the same and more from AVX512 galois field instructions

And 12700F that costs 300$ will already by slightly better. And one can build a system with 12700F or even better 12700K with DDR4 compatible board and 32GB of memory for under 800$. Ofc without GPU.
And for running NNUE based engine it beats 4000+$ M1 Ultra. Isn't that sweet .

Pls dont ever quote me ever again. You half knowledge is just too annoying.
Have you looked at the throughput and latency? Not to mention that AVX512 is DOA and Intel is suspected to drop it soon... Enabling AVX512 often makes every other process on the system run slower.

If you are using this in production code - measure what you did to everyone around you.
If anyone reads this: Sopel is a confirmed forum troll who is just very annoying to every thread he writes to.

M1 looks interesting - will wait for INDEPENDENT reviews.
