STOCKFISH CHESS ELO RATING PC
Reproducing chess scaling from 2020 History of PC Programs (ELO by year)Īs a baseline of engine performance over the years, we plot the winner from the yearly rating list of the Swedish Chess Computer Association. That's the aim of the current post (the other questions will be adressed in a later post). To sum it up, the hardware overhang in chess is about 10 years, or 2-3 orders of magnitude in compute.Ībout a year later, in July 2021, Paul Christiano asked similar questions: How much compute would the old engine need to match the current engines? What is the influence of RAM (size and speed), opening books, endgame tables, pondering? Also, my old post gave some insights, but it can be improved by sharing the sources and making it reproducible. I estimated that SF8 drops to Kasparov level on a 486-DX4 100 MHz, available already in 1994. With Stockfish, no supercomputer would have been required. That is an important year: In 1997, the IBM supercomputer "Deep Blue" defeated the world chess champion Gary Kasparov. When reducing compute to 1997 levels (equivalent to a Pentium-II 300 MHz), its ELO score was still ~3,000. I examined the strongest chess engine of 2020, Stockfish 8, performing at 3,400 ELO under tournament conditions. Hardware overhang is when sufficient compute is available, but the algorithms are suboptimal.
I had explored measuring AI or hardware overhang in August 2020 using chess.
