Cinebench
We used the ‘CPU’ test built into Cinebench R15 .
WinRAR
WinRAR’s built in benchmark and hardware test can help us outline the performance differentials between each motherboard. We record the amount of data processed after a 30-second run.
Handbrake Conversion
We measured the average frame rate achieved for a task of converting a 4.36GB 720P MKV movie to 720P MP4 format.
Regular Haswell showed tendencies towards 2666MHz in terms of real-world performance. 2666MHz always seemed the general sweet spot for DDR3 memory on an LGA 1150 system – any higher would start reducing performance due to loosened tertiary timings, whereas slower typically couldn't keep up purely due to frequency differences.
That same tendency is being shown by our Haswell-E system based around ASRock's X99 OC Formula. With its 2666MHz DDR4 and 3.5GHz CPU, the ASRock X99 OC Formula is able to outperform both the Asus and MSI boards in WinRAR, while it manages second place in Cinebench and Handbrake (joint with MSI's X99S Gaming 7).
Hey Luke, what attracts me to this board are the 2 x M.2 slots. Unfortunately you cannot run them in hardware Raid 0, but I believe you can software raid them in Windows. The other thing is do you know if the 5 year warranty is available worldwide? Or just the US/Europe?
