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 H.264 movie (in the MKV container) to one in the MP4 container.
There is almost nothing to tell each motherboard apart in our CPU-related benchmarks. Gigabyte's X99-UD4 is narrowly beaten in the Cinebench and Handbrake tests, but the performance difference is too small to mean anything (0.38% for Cinebench and 0.32% for Handbrake).
WinRAR puts both motherboards at equal performance levels.
