Overclocked Ivy Bridge-E Benchmarks: SANDRA, SunSpider
SANDRA TestingAs a quick sanity check we took at some SANDRA numbers first. SANDRA stands for "System ANalyzer, Diagnostic and Reporting Assistant." We ran three of the built-in subsystem tests that partially comprise the SANDRA 2013 suite with Intel's new Core i7-4960X processor (CPU Arithmetic, Multimedia, and Memory Bandwidth). The scores reported below were taken with the processor running at its default clock speed of 3.6GHz (4GHz Turbo) with 32GB of DDR3-1866 RAM running in quad-channel mode on the EVGA X79 Dark motherboard and then again overclocked at 4.6GHz with DDR3-2400 settings on our Corsair Vengeance Pro series memory.

In SANDRA's Arithmetic tests we see a gain of about 27 - 30 percent and again in Floating Point/AVX performance we see about the same. In terms of Memory Bandwidth, Corsair's 32GB kit scales up another 26% in memory bandwidth from 41.6GB/sec to 52.5GB/sec at 1866MHz CAS10 settings to 2400MHz CAS10.
SunSpider shows a massive gain for the overclocked Ivy Bridge setup, posting a time to complete in almost half the time of our stock 3.6GHz CPU / 1866MHz Memory system.
