Pedant And ASM

By the way, which is better and what is the difference between the two. Are they stockfish derivatives? How strong are they compared to Stockfish?
Thanks, Alfred

asmFish/pendantFish is equal to Stockfish of the same date. The difference is the programming language. Stockfish is written in C++ and asmFish in assembler which results in clearly higher search speed.

The ASM versions are a few points stronger - I would not suggest the results below are infallible, but Stockfish 8 on this list appears to be at least just as strong, if not stronger, using 8 cores as of the dev-version 170817 ( Aug 17 2017). The asm version are always a few points stronger ( maybe 20?) due to the increase in speed. I have never tested McBrain 2.7 at 8 cores - so I cannot speak to the validity of its ranking on the list below, but I do know in any chess match or RR, when it appears too good to be true , it usually is too good to be true. I expect that difference to get smaller as more games are played. These are 5 minute blitz games and as we know, fishtest never run games this long.

I wonder how Mr. Ipman got his computer up to 4.5 Ghz. Impressive.

asmFish and pedantFish now seem to be identical:

Q: Is asmFish search the same as official stockfish?
A: It does now that PEDANTIC = 1 is the default!

Before, pedantFish's search was identical to that Stockfish, and asmFish included some small optimisations that caused different node counts.

asmFish is a re-implementation of Stockfish in x86-64 assembly language. Functionally it is identical to Stockfish, but it runs faster.
