Cinebench R15
We used the ‘CPU’ test built into Cinebench R15 to measure the effect that system memory has on computational performance.
Super Pi 32M
We used the '32M' test in Super Pi to analyse the effect that system memory has on single-threaded performance.
Handbrake Conversion
We measured the average frame rate achieved for a task of converting a 4.36GB 720P H.264 movie (in the MKV container) to one in the MP4 container.
Cinebench took a consistent liking to the 2400MHz Crucial Ballistix Sport memory. This small points lead is within the benchmark's margin of error, although the consistency of the result may imply that the Micron DRAM chips have a little more to offer in terms of Cinebench performance.
Super Pi and Handbrake video conversion saw Crucial's kit matching the performance of G.Skill's 32GB Ripjaws4 with an identical operating speed.
The fact that DDR4 offers no tangible system performance increase over DDR3 with real applications is a good reason to not get suckered into buying empty promises with DDR4 which is intended for servers.
