Hi Gerhard,

just out of interest, is Leto using 8 physical cores or 4 cores with 8 threads?

Regards,
Graham.

From one of his other posts in the general forum, he is probably using an AMD FX8300.

Hi Graham !

AMD FX-8300 - 8 real cores.

The results will be very interesting, I'm looking forward to them.

The AMD might be 8 real cores, but they are structured as 4 modules with 2 cores each. The two cores in each module share certain resources. So they lose efficiency compared to a CPU that doesn't have those shared resources, but I'm not sure how much that affects chess.

+1

Just I'd like to add,
To be sure 100 % about the chess speed of AMD has real 8 cores or not .... We need to test in Auto232 mode: AMD 8c vs Intel 6c

Best,
Sedat

Better would be AMD FX8300 8 cores vs AMD Phenom II X6 6 cores

But it is 8 cores, kudos for testing with 8. I'm keen to see the results on the CEGT list, and the improvement from 4 cores.

The new update is online now:

Keep the less number of games for some engines in mind !
