Stockfish 14092119 x64 vs. Komodo 8 x64 - One on One, 100 Rounds 5M+3S

It's been a while since the last test of Stockfish development version. Komodo 8 came along and almost took the crown of Stockish as number 1 in blitz 1+1 time control. It was claimed by the Komodo team that Komodo 8 is the number 1 in sites with longer time control such as IPON, CCRL and FCPC but all of them are using the older versions of Stockfish.

Now that the Stockfish team was energized again to publish the latest development versions after a long drought, it is time to see whether Komodo 8 is strong in 5+3 time control similar to IPON's.

The version chosen for Stockfish was the latest generic x64 build 14092119 released on September 21, 2014, while Komodo's was the latest version 8. The match is a 100 games round robin done in 2 similar specs AMD Quad Core A8-5600K CPU with 8GB physical memory.  The operating system used was Linux 3.16.2 with WINE, eliminating windows for better performance. There were 6 simultaneous games for each computer with only 1 core for each instance and 128MB of hash was allocated, this was controlled by Arena GUI. The match started today, September 23 at 14:48:32 and ended at 17:54:41 with a duration of 3 hours, 6 minutes and 9 seconds for the whole 100 games.
