If you compare the 64-bit speed to the 32-bit speed
(infinite analysis of the start_position, 1-cpu/thread for reproducibility),
you get:
+70% for Rybka 4
+25% for Stockfish 1.9
So compared to Rybka, Stockfish should perform quite a bit better in 32-bit!
In the rating lists, the Rybka-Stockfish gap should be around 30 Elo less in 32-bit than in 64-bit.
Compared to Rybka, Stockfish should score better in 32-bit!

Re: Compared to Rybka, Stockfish should score better in 32-b
Seems to be true, because in CSS forum:
Stockfish 1.9.1 JA v/s Rybka 3 58 - 42 (+ 39,= 38,- 23) !
But I don't understand why test is done with 1 cpu (no ponder) in dual PC??

Very True.
Computer here is 32 bits and this is precisely why I see such a good improvement from Stockfish 1.9 in STS test.
Best wishes,

Hi Jouni,
look here, SWCR results:
Between SF 1.71 x64 to w32 = +20 ELO
Between SF 1.80 x64 to w32 = +38 ELO
Now SF 1.9.0 / 1.9.1 are available.
SF 1.9.0 JA w32 = 336.384 bytes
SF 1.9.1 JA w32 = 206.336 bytes
I think the different results for the latest w32 versions have to do with the compiles from Jim.
Same for SF 1.6.0 up to 1.6.3
The Stockfish team sayed ... same playing level, no changes ...
But look here, again my SWCR results:
A bit confusion for myself and mental confusion in SF w32 results for the SWCR visitors.
Not sure, but I believe that the compiles Jim made are variable for the 32bit versions.
Version 1.9.1 not tested yet in SWCR. Many work with the IPP family test. SF 1.9.1 w32 / x64 comes a little bit later.
Best

Re: Compared to Rybka, Stockfish should score better in 32-b
With 64b and dual I got in full STS 1300 position / 10s:
Rybka 3 1164 / 42m
Stockfish 1.9 1099 / 54m
They should be very equal.
