The Sisoftware Sandra 2012 SP3 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 and CPU performance!
Looking at the performance numbers from SiSoft’s memory bandwidth testing, the overall memory bandwidth on the ASUS P9X79 Deluxe motherboard gives us a staggering 41.715 GB/s aggregate memory bandwidth vs the aggregate memory bandwidth of 24.775 GB/s on the P8P67 EVO and the aggregate memory bandwidth of 23.825 GB/s on the Rampage II Extreme. Which I will have to say is a pretty significant increase of memory bandwidth.
Looking at the memory latency on each of the tested platforms, this time around the 2600K CPU gives us the best overall speed in regards to the memories latency rating. Will having roughly a 5 ns difference in time be enough to tell the difference? Depends on the application and what you are using your computer for, but for the most part you will not be able to tell the difference.
