Both engines played with the same book to moves 6.

What is the fastest GPU that I can get to run LCZero? Any recommendation from this page ==>

Or should I simply purchase this system ==>

Hi

is it really 16GB hashtables for Stockfish??
I think its too high for that time controll. Will not affect the game too much.
Thinking per move is average 1min?

Anyway, thx for the match.

16 GB is too much for 7,5 s per move. TCEC uses 16 GB for 5 hour games with 43 cores. Which one were more expensive GPU RTX 2080 ti or Threadripper?

I am not sure why you think 16gb of hash in quad channel memory is hurting stockfish. It does not. It may not help but does not hurt performance in any meaningful way. It is just easier to save certain profiles for testing multiple time controls. Now testing at 15 mins for 40 moves using 16gb hash.

The RTX 2080 ti cost much more then the cpu.
