Ivy Bridge-E Overclocking With EVGA And Corsair
Overclocked Ivy Bridge-E Benchmarks: SANDRA, SunSpider
SANDRA Testing
As 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 Testing
Next up, we have some numbers from the SunSpider JavaScript benchmark. According to the SunSpider website: This benchmark tests the core JavaScript language only, not the DOM or other browser APIs. It is designed to compare different versions of the same browser, and different browsers to each other. Unlike many widely available JavaScript benchmarks, this test is real world, balanced and statistically sound.
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.
