The latest CCRL Rating Lists and Statistics are available for viewing from the following links: (40/15) (40/2) (FRC 40/2)

Please note that the three lists are often updated separately to each other. The FRC list is only updated when a new engine or engine version is being/has been tested.

The links to the various rating lists can be found just beneath the default Best Versions list (as in this screenshot). Specific 32-bit rating lists are denoted as such to the right of the default list in each category. The default lists contain the 64-bit engines.

CCRL 40/15, 40/2 and FRC lists updated (19th September 2020) CCRL-lists

Our 40 moves in 15 minutes repeating and 40 moves in 2 minutes repeating are both adjusted to the Intel i7 4770k (3.5GHz) using the Stockfish 10 64-bit benchmark.

Be aware that in the early stages of testing, an engine's rating can often fluctuate a lot.
It is strongly advised to look at the many other rating lists available in order to get a more accurate overall picture of an engine's rating relative to others.

The inclusion or exclusion of engines in our lists should not be taken as our group making a statement about their legality or status. Where there is controversy, it is usually mentioned in the engine notes.

Thanks to all of our currently active testers (Graham, Ray, Gabor, Sergio and Volodymyr). Thanks also to for hosting our website.
