But then we have to take the amount of computing power
(nr of cpu and speed of cpu's) into account.
This has a major influence on UCT/MC programs.
Otherwise we only test the package of progam+computer together
and not the progam alone.
Speed differences of more then 10 exists in the rating pool...

In the many chess computer rating lists, the entities in the list are determined by:

1) Program, including version and settings (e.g. standard vs. hyper- modern) 2) Platform, including processor, clock speed, number of cores, and amount of memory devoted to transposition tables

Sometimes the entities are even distinguished by which opening book or endgame database is in use.
