Intel Core i7-2700K Sandy Bridge 3.5 GHz CPU ReviewMon, Oct 24, 2011 - 12:00 PM
SiSoftware Sandra 2011 SP5
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: All of test systems used the identical Corsair Vegenance Series 8GB (2 x 4GB) memory kit that ran at 1866MHz with 9-10-9-28 1T timings with the exception of the AMD Phenom II systems that were run at 1600MHz with CL9 timings. As you can see the Intel processors come out better than AMD when it comes to memory bandwidth. The Intel Core i7-2700K had a memory bandwidth speed of 24.5GB/s when run in dual-channel memory mode at 1866MHz.
The Sandra Processor Multi-Media benchmark has been a long time
favorite of ours to look at floating point performance on processors.
The Intel Core i7-2700K processor performed just a tad better than the 2600K, which is what we expected for only having a 100MHz clock speed increase.
