The Sisoft Sandra XII SP1 benchmark utility just came out a couple months ago and we have started to include it in out benchmarking. With Sandra XII SP1 you can now easily compare the performance of the tested device with its speed and its (published) power (TDP)! Sandra XII SP1 also has SSE4 (Intel) and SSE4A (AMD) benchmark code-paths, which is great for those of you testing next-generation AMD & Intel chips.
Results: Sandra XII SP1 showed that the X4 9850’s higher (2.0GHz) memory controller and HyperTransport speeds really does help when it comes to memory bandwidth. The AMD Phenom X4 9850 had the highest memory bandwidth of any non-overclocked system that we have ever seen.
