Re: M1 Apple Silicon for Chess?

Chip with trash for IO consumes less energy than a big x570 board that has a ton of IO who would have thought? Once they start adding IO energy consumption will rise with it. Not because ARM is inherently superior but because Apple can take the cost of making their systems efficient. Apple doesn't h...

Re: Simplified chess variants?

Makruk and Seirawan are "extremely" simple. But an 1800 elo player has no chance of playing perfectly. Seirawan chess is not simpler than FIDE chess. The rules are a superset of FIDE rules and the game tree is bigger too. I don't know about Makruk but it looks about the same as FIDE chess. In this ...

Re: M1 Apple Silicon for Chess?

That depends on which 4000U series CPU you take into comparison. 4900U will almost certainly blow M1 out of the water. I don't think so, even if the 4900U were not made of pure unobtanium. Geekbench 5 lists the M1 around 7500 in multicore. The fastest 4800U samples are around 7700 (generally rather...

Re: 4 x Intel Xeon good idea?

His claim is unsupported so unless proper tests demonstrate that the scaling efficiency actually got worse, I'd just assume it was rubbish. The proper measure of scaling efficiency of N threads is finding the time factor X needed so that 1-core with X*T time scores 50% against N-cores with T time. ...

Re: Pytorch NNUE training

Gary, I'm trying to output my networks with an SF format. You have a couple different versions going in in your repo, but do https://github.com/glinscott/nnue-pytorch/blob/master/serialize.py and https://github.com/glinscott/nnue-pytorch/blob/master/model.py correspond to what would be matching Nod...

Re: 4 x Intel Xeon good idea?

Since it's a Xeon V2 it will not support AVX2 incase you want to run NNUE engines with it.
