SiSoft Sandra Memory Bandwidth
SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information & diagnostic utility. It should provide most of the information (including undocumented) you need to know about your hardware, software and other devices whether hardware or software. It's available in five versions, ranging from the free "Lite" version to the Sandra Enterprise version. Sandra fully supports and exploits multi-processor and multi-core systems, NUMA memory, Hyper-Threading, and MMX, SSE, SSE2, SSE3, SSSE3, SSE 4.1, SSE 4.2, AVX, and FMA instructions.
It comprises a massive suite of test and reporting features...but the one I'm interested in is the memory bandwidth test: SiSoft's memory bandwidth test provides individual and aggregate scores across a variety of memory operations. For this test I'm reporting the aggregate score. Does the new quad-channel memory system really make that much of a difference?
And the answer is yes...yes it does. But the Sandy Bridge Extreme memory controller has even more up its sleeve: although not shown on this chart, the Intel Core i7-3960X turns in better dual-channel memory bandwidth than a Core i7-2600K, and better triple-channel bandwidth than a Core i7-980X.
