Fast, easy to use, PC speed testing and benchmarking. PassMark PerformanceTest allows you to objectively benchmark a PC using a variety of different speed tests and compare the results to other computers. Twenty-eight standard benchmark tests are available in six test suites plus there are seven advanced testing windows for custom benchmarking.
If we look at PerformanceTest we can see that the numbers start to change a bit. Here we see that at stock, when comparing the performance of the three setups the X79 doesn't lag behind like it does in AIDA64. At the same time, no real difference is being shown and while our overall memory mark goes up for Quad Channel on the X79 platform when compared to the Dual Channel scores, there's nothing exceptionally strong about it.
Overclocking paints a little bit of a different picture. All setups of course see a boost in performance, but you can see our Quad Channel setup really begins to see some breathing room when it comes to the write performance with an increase of over 20% when compared to the two Dual Channel setups. This helps push our overall Memory Mark up, but you can see that there's little difference in overall read performance.
