Re: Can an engine calculate how fast Human GM lose ratings after 55 ?

Do go on! It's always interesting to hear about the absurd and logically indefensible ideas that people form in their little heads without the slightest shred of evidence. It's even more entertaining when those beliefs reveal one to be not only a raving lunatic, but also raging bigot. High cortisol...

I have a belief that chess strength has something to do with Testosterone levels. It declines as we age and Testosterone is much lesser in females.

With Computer 4 times fasters and much better Engines than today :mrgreen:
That is possible even today as long as the engines favor complexity over best moves.

Re: M1 Apple Silicon for Chess?

Its what you get by running bench from the command line, which is classical and (hybrid) NNUE on alternate positions. stockfish bench 64 8 20 default depth NNUE gives 9818973 (8 cores using just hybrid NNUE) stockfish bench 64 8 20 default depth classical gives 16097762 which is as fast as my 8-cor...

Re: M1 Apple Silicon for Chess?

But Apple M1 has neural engine processors. Maybe NNUE can be optimized for it?

Re: M1 Apple Silicon for Chess?

As far as I have observed chess engine speeds for 2 decades I noticed that it benefits a lot from larger L1 cache size. For the record, our mainstream x86 CPUs have 32kb/32kb L1 cache while this new apple M1 has gigantic 192kb/128kb!

That seems to be Helium. Surely it will be faster for NNUE than ARM general purpose - whether it is better than NEON - per Watt, yes.
For instance Huawei was talking about Dual Neural Processing in their ARM CPU while Qualcomm talks about Hexagon NN. I believe it's more than just Helium.

Re: CPU Vector Unit, the new jam for NNs...

What do the latest ARM CPU with AI acceleration offer in comparison? ARM has Advanced SIMD aka NEON , a combined 64- and 128-bit SIMD instruction set. But NEON is old. I heard that AI acceleration in recent ARM flagships especially in Huawei's Kirin are being showcased with far leading benchmarks i...
