Code:


vs Naum 3.1 x64 4CPU           65.5-34.5
vs Zappa MX II x64 4CPU        70.5-29.5
vs Hiarcs 12 4CPU              68.0-32.0

Level 40/3+40/3+...
128MB HTs each
no TBs
Ponder=off
50 positions, each with White and Black

Is it Vista 32- or 64-bit you use ?

Hi Gerhard,

thanks for your post. It shows that Rybka 3 1-CPU stay unbeatable against 4-CPU opponents.
I'll try to do the next test of Rybka 3 1-CPU against Toga II 4-CPU.
I use Windows Vista 32-bits.

Best,
Orlando

Thanks for your work, Orlando, and the aggrgation, Gerhard.
Strong R3!

This fits very good to the Ranking in
http://www.husvankempen.de/nunn/40_40%20Rating%20List/40_40%20All%20Versions/rangliste.html

1.) Rybka3 x64 4CPU
2.) Rybka3 x64 2CPU
3.) Rybka3 w32 2CPU
4.) Rybka3 x64 1CPU

Interesting is, that in this CEGT-List even 'Rybka 3 w32 1CPU' lays in front of all not-Rybka-Engines running on 4 Cores.
And the strongest 'Rybka 3 w32 1CPU'-follower is Zappa Mexico II on 4 Cores with 64 bit.
And that hardware-pushed Zappa has anyhow 37 ELO-points less than that 'Rybka on Hardware for poor people"

Orlando, do you feel delight to do such a series with that 'Rybka 3 w32 1CPU'?

Another interesting question:
If 'Zappa Mexico II 64bit' plays on a modern quad, how flabby must the opponent machine with a 'Rybka 3 w32 1CPU' be, so that these Engines play a 50:50-match over a larg number of games? Which Rybka3-Processor-frequency would fit?

I suppose a "50-50" would be possible if
Rybka 3.0 w32 1CPU (1x2.4GHz) play against:

Naum 3.1 x64 4CPU (4x2.4GHz)
or
Zappa MX II x64 4CPU (4x2.4GHz)
