Sandra 2009 Memory Bandwidth

Sisoftware Sandra 2009

The Sisoft Sandra 2009 benchmark utility just came out recently and we have started to include it in our benchmarking. With Sandra 2009 you can now easily compare the performance of the tested device with its speed and its (published) power (TDP)! Sandra XII SP2 also has SSE4 (Intel) and SSE4A (AMD) benchmark code-paths, which is great for those of you testing next-generation AMD & Intel chips.

Sandra 2009 SP2 Benchmark Scores

Results: Sandra 2009 SP4 showed that the Intel Core i7 870 with the dual channel memory running at 1600MHz with 8-8-8-24 timings was just shy of reaching 20GB/s of memory bandwidth.  The Intel Core i5 750 processor with the dual channel memory running at 1333MHz with 8-8-8-24 timings had 17GB/s of memory bandwidth, which is nearly half of what we were able to reach with the Intel Core i7 975 processor and the memory running at 1866MHz with 8-8-8-24 timings.  Clearly the Intel Core i7 870 and Core i5 750 processors will have less memory than the LGA 1366 processors since they are just dual channel, but will that matter in real world tests and in the games?
