>>Correct me if I am mistaken, but the link you provided shows all versions compared to each other.  So a 1 cpu 32 bit is being compared to a 12 cpu 32 bit.

You can click on the link of each engine to see which games it played.

>>Thats not what I was talking about.  The link I provided is dated November 28th, 2015, so I don't think it is outdated at all.

That list is absolutely outdated. Just look at the versions of the programs. Rybka 3 is the latest version of Rybka listed, 13 is the latest version of Fritz, 2.01 is the latest on Stockfish, and Komodo 1.3 is the latest of Komodo. Rybka 3 is over 7 years old. I think the date at the top of that page just reports when any page on the site was last updated.

What I think is happening here is that CCRL simply stopped testing 32-bit engines around 5 years ago, so when you search for 32-bit only you're effectively setting a latest date of around then. Well it's a bit more complicated than that, they appeared to have stopped testing 32-bit versions of an engine if a 64-bit version was available, and did not test any new 32-bit engines after that. Maybe Graham can clarify.

>>And, the link I provided only compares 1 cpu 32 bit with other 1 cpu 32 bits.

That's what's listed, the engines actually play against all different ones, including 64 bit engines, and engines running on more than one core. Again, you can click on an entry to see which games it played, but there aren't going to be much for some of them because like I said I think they stopped testing 32-bit engines a while ago.

>>Am I missing something here?

Also it's kind of a moot point that the 32-bit engines on 1 core are being tested against other 64-bit engines on multiple cores and all the combinations therein. Elo is Elo, the higher rated engine is surely stronger here given the number of games and number of competitors.
