Stockfish testing
 
Playing conditions:
 
Hardware: i7-2630QM 2.0GHz Notebook, Windows 10 64bit, 4GB RAM
Fritzmark: singlecore: 3.97 / 1905 (all engines running on one core, only), average meganodes/s displayed by LittleBlitzerGUI: Houdini: 2.0 mn/s, Stockfish: 1.7 mn/s
Hash: 128MB per engine
GUI: LittleBlitzerGUI (draw at 120 moves, resign at 450cp (for 4 moves))
Tablebases: None
Openings: 10moves_SALC_500.epd (download the file at the "Download & Links"-section)
Ponder, Large Memory Pages & learning: Off
Thinking time: 70''+700ms per game/engine (average game-duration: 3.5 minutes)(standardized to the hardware-speed and the thinking time of the excellent [You must be registered and logged in to see this link.]). One 7000 games-testrun takes about 6 days (running on only 3 of 4 cores). The version-numbers of the Stockfish-development engines are the release-date, written backwards (year,month,day))(example: 141028 = October, 28, 2014), downloaded at [You must be registered and logged in to see this link.] I always use the latest version of one day, if more than one version per day is released. And I use the version "for modern computers". (At the moment, the compiles for modern windows machines on abrok.eu are around 8% slower, so I dont use them anymore)
 
Each Stockfish-version plays 1000 games against Komodo 10.2, Houdini 5, Shredder 13, Gull 3, Fire 4, Critter 1.6a and Equinox 3.3.

Below you find a diagram of the progress of Stockfish in my tests since the end of 2016
And below that diagram, the older diagrams.
 
You can save the diagrams (as a JPG-picture (in originial size)) on your PC with mouseclick (right button) and then choose "save image"...
The Elo-ratings of older Stockfish dev-versions in the Ordo-calculation can be a little different to the Elo-"dots" in the diagram, because the results/games of new Stockfish dev-versions - when getting part of the Ordo-calculation - can change the Elo-ratings of the opponent engines and that can change the Elo-ratings of older Stockfish dev-versions (in the Ordo-calculation / ratinglist, but not in the diagram, where all Elo-"dots" are the rating of one Stockfish dev-version at the moment, when the testrun of that Stockfish dev-version was finished).
