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.
The memory bandwidth test within Sandra's test suite will give us the best idea of how the quad-channel memory system affects memory bandwidth.
The tests show very clearly that the quad-channel memory improves bandwidth speeds. The i7-3820 even outperforms the 980X because of this quad-channel memory support. The improved memory controller on the LGA-1155 CPUs is enough to boost the i7-2600K up over the 980X as well.
