The Sisoft Sandra 2011 SP5 benchmark utility just came out a few weeks
ago and we have started to include it in our benchmarking. Sandra 2011 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 and CPU performance!

Sandra 2011 SP5 Memory Benchmark Scores

Results: The Intel Core i7-3960X and 3820 both use quad-channel DDR3 memory and the memory bandwidth numbers are impressive. If you need tons of memory bandwidth for what you do, then there is no other platform to choose. The IntelCore i7-3820 processor that we are focusing on today was running Corsair quad-channel DDR3 1866MHz memory and had ~37.4GB/s of memory bandwidth.  The Intel Core i7-3960X had 39.5GB/s of memory bandwidth, but this is likely due to the extra cores and L3 cache.

The Sandra Processor Multi-Media benchmark has been a long time
favorite of ours to look at floating point performance on processors.

Sandra 2011 SP5 Benchmark Scores

The Intel Core i7-3820 performed decently in the Sandra processor multi-media benchmark, but as you can see it was only marginally faster than the Core i7-2700K.
