Sandra 2009 Memory Bandwidth
Sisoft; 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.
Results: Sandra 2009 SP2 showed that the Intel Core 2 Quad Q9550 processor had roughly the same amount of bandwidth that the other processors did that were running DDR3 1333MHz memory kits with CL7 timings. The Intel LGA775 based processors are never going to get better than this as the memory controller is in the chipset and not the processor. The Intel Core i7 series has an integrated memory controller in the processor and triple-channel DDR3 memory, so that is the reason it blows away the other Intel processors.
