Re: I did some magic bitboard "science" and mostly learned not to worry about it

Interesting, so it boils down to lookup vs computation. From Ankan's gpu perft: - Move generation uses bitboards -- position represented using a set of 6 bitboards -- two variations for sliding piece move generation: kogge-stone and magics --- three variations of magics: plain, fixed shift fancy, an...

Re: DDR5 RAM is coming in 2021

Is anyone fired up about this? No. It's been some time since I was a teenager. For me a computer is a tool to get stuff done (or play games).

Re: larger nets for SF?

... But why shouldn't the SF team double, quadruple, and so on the size of the net until no more Elo falls out of it? ... I think it is a trade-off, bigger nets = less nps = shallower AB searches. Elo gain by bigger nets vs. Elo gain by deeper searches, or alike. With more horse-power from vector u...

Re: GPU rumors 2021

Ah, I missed one rumor:

- Nvidia RTX 30xx Super series refresh on TSMC 7nm in 2021?

https://www.thefpsreview.com/2020/10/09 ... m-process/

Dunno how this chip shortage thingy will play out in all of this.

chess per se makes sense, it might be an own world/dimension for itself, but I
guess that is the beauty in it.

Re: M1 Apple Silicon for Chess?

As far as I got it the M1 has 4 vector 128b NEON pipelines per Firestorm core: https://www.anandtech.com/show/16226/apple-silicon-m1-a14-deep-dive/2 can someone clarify how these are used for NNUE? Does SF utilize only one 128b pipeline, or can they be coupled to 512b? -- Srdja According to SF and ...
