Hi all,

how many more knodes and how many elo points or how much more speed can sse4 instructions give an engine?

I don't know anything about programming and i wonder if there's a substantial difference in performance.

Thank you

Best Regards



I have seen references (mainly in connection to Komodo) that SSE 4.2 compiles are 10% to 15% faster. Also, engines seem to gain 50 to 120 Elo per doubling in speed, depending on the engine and the base time control (probably even less gain as the base time control increases). So a rough guess at the increase in Elo would be as little as 5 to 7 Elo to as much as 25 Elo.


Thank you Smile

Regards
