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 XMP Profile 1 or 2 we were seeing 107.2-107.5 FPS on pass 1 and right around 29.2 FPS on pass 2. This is a significant 6.1% performance increase on the second pass with the 2666MHz or 3000MHz settings, so if you do a ton of video work you’ll really want to consider a DDR4 memory kit with clock speeds above 2133MHz as it will save you significant time on your rendering jobs over the years and many people are buying Haswell-E platforms for CPU intensive tasks like that.
