Intel Sandy Bridge-E Review - Core i7-3960X and X79 Chipset Tested
Synthetic CPU and Memory Tests
SiSoft Sandra 2011
The latest version of SiSoft Sandra offers up a lot of new features including GPU performance, OpenCL, etc.
The CPU performance of the Core i7-3960X doesn't look like it will/can be challenged from a purely synthetic stand point and the memory performance numbers impress as well. It looks like adding in the quad-channel memory controller at least has a CHANCE of improving performance on software that is is any way memory bound.
