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 ...

Followup: - I mixed up NNUE first layer INT16 and further INT8 weights, so the possible 4x inference speedup holds only if we assume 8-bit vector packed math on gpu. - I was not able to implement an efficient 8-bit 0x88 vector-based board representation on pen n paper, hence no 8-bit speedup for mov...

In the beginning it was less.
Maybe 1600-1750 Elo when the software was 16 kb size and hardware maximal 3.6 mhz.

Hehe, my favor - Video Chess from 1978 for the Atari VCS gaming system:

- 8-bit 6507@1.19 MHz
- 128 Bytes RAM
- 4 KB ROM cartridge

... Great points made!! I have to say also that many Apple users I come across in my work have tended to get very aggressive for the slightest criticism of their HW/SW on a personal kind-of level, so sometimes it feels like you have to walk on eggshells. It's not surprising to me scientific studies...

Modern Times is right: not only CPU, but all components on the SOC and SSD are stressed with 91° Celsius FOR DAYS in a 15x15 cm box (fan increases from 1700 RPMs only when >90° )

I killed one CPU-fan in my Thinkpad with chess eniges -> pro chess on pro workstations.

Haha, ChessBase on the 'Bongcloud Attack' ;) "New: Arne Kaehler - The Discombobulating Bongcloud Attack " In the last couple of years, the Bongcloud Attack struck the chessworld by surprise. Even top Grandmasters like Magnus Carlsen or Hikaru Nakamura seem to want to play this nebulous opening more ...

I just looked up and AMD has the little Navi 24 in pipe, with 1024 or 1280
cores, 32 resp. 40 SIMD units, maybe I will give it a try when this gpu-price
madness settles...
