Stockfish on OpenBenchmarking.org

Did you know, that stockfish is part of the "Phoronix Test Suite" and used on this site:

Looks like something is wrong. The AMD Ryzen 1800x is showing as slower than a plethora of other AMD chips. I doubt they have 8 cores in use.

The AMD Ryzen 1800x is the fastest AMD on this graph "ms, Less Is Better".

Oops - my mistake!!

Well, you're not wrong, though

Unless I'm missing something when looking at how they run that benchmark, they just call bench with no parameters, so it's only going to be a single-threaded test anyway.

Cheers!

I have computers with two of the listed processors (i7-4790K and Ryzen7 1800x) and the performance they measure is consistent with the single-threaded performance I observe.

I somehow expected something of that sort...
I can make somewhat sence of that, since the goal of the topic is to test the cpu performance only. If you would ran all physical cores, they would start to compete for the L3-cache, this would distort the result.

Does there exist a comparable benchmark, that points to the best chess machine reliably?

[Geonerd]

Yup. Otherwise, the Ryzen 5 sure wouldn't be splitting two R7 8 core chips!
