Intel Xeon E5-2600 & R2000GZ Sandy Bridge-EP Server Review

SiSoftware Sandra 2012 SP2 Memory Bandwidth

The SiSoft Sandra 2012 SP2 benchmark utility just came out a few weeks
ago and we have started to include it in our benchmarking. Sandra 2012 comes with
support for Virtualisation (Virtual PC/Server, Hyper-V, VMware) and
GPGPU (OpenCL, DirectX 11 DirectCompute), but today we will be using the
program to look at memory performance!

Benchmark Results: The Intel Grizzly Pass server has an impressive 128Gb of memory in a quad channel configuration. That’s 64Gb of RAM for each of the Intel Xeon E5-2660 CPUs to work with. Looking at the results above we can see that we topped out at 72.372GB/s on the Integer memory bandwidth test and 73.436GB/s on the Float Memory bandwidth test. In comparison our Intel X79 test bench is typically just above 40GB/s on both tests.
