Page 4 - Performance: WPrime, SuperPI
WPrime
WPrime is famed for being one of the best optimized benchmarks for multi-threading CPU as whole. Its name though is a tad misleading. Since it does not calculate prime numbers bur squares.

Undoubtedly results are indicative. More threads = faster result computation, much faster indeed. But we cannot explain the reason because of which AMD Phenom II 810 X4 is performing better that its bigger brother - 940. This is the only test that tests the processors computational power in the first place in which we saw this phenomenon.
SuperPI
SuperPI will remain in history as one of the first massively used tools for processor performance testing. The program exists for over a decade now and back in the day when 32M PI computation took 24 hours on the 90MHz Pentium it was considered a stability test too. We used modified version from XtremeSystems, that adds multi-threading to some degree (sadly still incapable to fully load all cores) and as you can clearly see the dual-core 8400 with slightly raised frequency fares just as good as its quad-cored equivalent.

Phenom II X4 demonstrates considerable performance compared to the 9850 X4, but are still trailing behind Intel processors at the same frequency.
