--------------------------------------
A: hardware konfiguration 1
B: hardware konfiguration 2
C: number of engines with that combination
D: Elo-average 1
E: Elo-average 2
F: Elo-difference
A B C D E F
-----------------------------------------------
x64,6CPU - x64,4CPU, 9, 3006.1,2986.2 , 19.8 27.9
x64,4CPU - x64,2CPU, 61, 2850.6,2809.8 , 40.8
x64,4CPU - x64,1CPU, 56, 3085.1,2985.3 , 99.7 49.9
x64,2CPU - x64,1CPU, 81, 2730.9,2680.7 , 50.1
w32,2CPU - w32,1CPU, 19, 2699.5,2645.0 , 54.5
x64,2CPU - w32,2CPU, 5, 2697.6,2644.8 , 52.8
x64,1CPU - w32,1CPU, 25, 2819.1,2790.2 , 28.9
redoubling the number of CPUs gives 10628/226=47.0 Elo-points
changing from w32 to x64 gives 987/30=32.9 Elo-points
