Average result: 48.33%

Some surprising results, with a clear difference between AMD and INTEL versions. In my quad (4 real cores no HT) the Intel version gets a 50.83% against the three top engines, but AMB version is much worse (only 42.50%).

On the other hand, using 6 real cores, the AMD version gets an impressive 52.50%, whereas INTEL gets a mere 44.17%.

I will repeat the tests fot INTEL 4 cores and AMD 6 cores to minimize the statistical effect. But by know, very promising results for the tandem Ofry + Peterpan. Very well done!!.

Regards from Barcelona.

I will repeat the test to confirm -or not!- the result and minimize the statistical noise. Globaly I expect around 50% both against Critter 1.4a and Deep Rybka 4.1 and 42% against the monster Houdini 2.0c Pro.
