AMD EPYC Genoa Chess bench with 2x192 threads

Post by Vinvin »

Not a lot of details about the version of the executable.
The CPU reached > 600 Mn/sec with 2x192 threads, but test is rigged : "A major challenge here was that our benchmark stopped scaling at 256 threads. We had to split the benchmark up to run in two 192-thread instances via containers to get the result above. Otherwise, a third of the chip was not being used."

"The award-winning Stockfish chess engine is designed for the utmost scalability across core counts — it can scale up to 512 threads (so we still have just a bit of scalability left before Bergamo arrives). Here we can see that this massively parallel code scales well with EPYC's leading core counts as the 96-core EPYC 9654 provides more than twice the amount of performance of the 8380s. Also, note the 64-core EPYC 9554's solid 33% increase over the previous-gen 64-core EPYC 7763. That big jump in performance makes the 15% gen-on-gen price increase for 64 cores feel a lot more palatable. "
