Lowest rating for Tornado 2.2 w32 2CPU is 2610-38 = 2572.
Highest rating for Tornado 2.2 x64 2CPU is 2602+38 = 2640.

Matthias.

mean that x64 version have 2602 (without +- 38)
and that w32 version have 2610 (also without +- 38)

but 240 games maybe not enough to get exact rating differenz

[ernest]

With infinite analysis on the start_position (using 1 Thread, for reproducibility), I found that Tornado 2.2 x64 is 40% faster than w32.

This means that the x64 should be approximately 35 Elo stronger than w32.

With more games, today's -8 Elo will be certainly be replaced by a positive Elo (unless something is wrong )
