ASUS Rampage IV Extreme Motherboard Review

SiSoftware Sandra 2012 Sp1 Memory Bandwidth Benchmark

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!

Results: There is no doubt that the Intel X79 Express chipset brought with it some solid gains in memory performance. Having the ability to run the memory in quad channel is a great option, not to mention it is incredibly fast! The ASUS Rampage IV Extreme was able to edge out the GIGABYTE GA-X79-UD7 in both the Float and Integer Memory Bandwidth tests. Though we are looking at only a difference of .053GB/s or .13% in the Float Memory Bandwidth B/F AVX/128 test and .09GB/s or .22% in the Integer Memory Bandwidth B/F AVX/128 test. Clearly the margins are slim and wouldn’t pose any real world advantages.
