RealBench
RealBench uses real, open source applications to test your PC as it would perform in RL. Although it can be competitive, it’s not primarily designed to be more hardcore and time-consuming – it’s a benchmark for everyone.
Select the three tests and run the benchmark to get your result. Each test uses different parts of your PC subsystem, so all areas are covered. Compare to others, or, compare to pre/post overclocks and pre/post upgrades to get maximum value from your PC.
The Heavy Multitasking portion of Realbench shows the Crucial Ballistix Sport kit  a fraction of a second behind the faster Kingston Fury kit.
The image editing test in Realbenh shows how little difference you really get going from 2400MHz to 2666MHz and in this case it’s about 2 seconds difference.
The image encoding portion of Realbench sees pretty much the same thing as the Image Editing portion and the Crucial Ballistix Sport kit comes in a couple of seconds slower. The biggest difference you are going to see in kits with different speeds are memory oriented tasks and tests. Rendering or BitCoin mining it might make some difference but everyday uses it doesn’t make much difference.
The OpenCL test and all tests having to do with interaction of the GPU with the rest of the system we always use the same R9 380 4G and the scores reflect the strict testing procedures we use and the two memory kits are separated by 25KSamples/sec.
