x264 HD Encoding


Simply put, the x264 HD Benchmark is a reproducible measure of how fast your machine can encode a short HD-quality video clip into a high quality x264 video file. It’s nice because everyone running it will use the same video clip and software. The video encoder (x264.exe) reports a fairly accurate internal benchmark (in frames per second) for each pass of the video encode and it also uses multi-core processors very efficiently. All these factors make this an ideal benchmark to compare different processors and systems to each other. We are using x264 HD v5.0.1 for this test. This application scales across many threads and is ideal for processors with Intel Hyper-Threading or a bunch of cores.



Benchmark Results: The x264 HD v5.0.1 benchmark showed that at 2133MHz with CL14 timings we were averaging 98.96 FPS on pass 1 and 27.49 FPS on pass 2. When we set the UEFI/BIOS to the XMP Profile on the G.Skill F4-3000C15Q-16GRR memory kit we were getting 107.49 FPS on pass 1 and 29.2 FPS on pass 2. Once you get over 2666MHz it doesn’t appear that memory bandwidth is a limiting factor for this test as we saw little performance difference on the 3000MHz kits and even if we used tighter timings. There was no significant difference in the results and most of what you are seeing is normal variance between benchmark runs.
