I presume some/many are specifically optimized and highly-tuned for running best on Intel processors: https://software.intel.com/en-us/gamedev/ https://software.intel.com/en-us/gamedev/ But also things like physics engines (eg. Havok, which was acquired by Intel and heavily optimized for Intel processors), etc. And of course Intel's C Compiler is known to cripple AMD: http://www.agner.org/optimize/blog/read.php?i=49 http://www.agner.org/optimize/blog/read.php?i=49 And some/many games are compiled with ICC...
