Page 7 - Performance: WPrime, SuperPI
WPrime
WPrime is famed for being one of the best optimized benchmarks for multi-threading CPU as whole.

Undoubtedly results are indicative. More threads = faster result computation, much faster indeed. The Intel Q9550 architecture clearly has the edge and does calculations about 30% faster than AMD Phenom II X4 940.
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 older Phenom X4, but is still trailing behind Intel processors at the same frequency.
