x264 HD Encoding
Simply put, it is a reproducible measure of 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.
Benchmark Results: The x264 HD benchmark is said to be ideal for a benchmark because the application reports fairly accurate compression results for each pass of the video encoding process, and it uses multi-core processors very efficiently. The Intel Core i7-2820QM processor was ~75% faster than the Intel Core i5-540 processor on the first pass. On the second pass the Core i7-2820QM processor was found to be 2.25x faster than the Core i5 540 mobile processor. Intel has done plenty of improvements to the core for improved video editing and you can see that the efforts have paid off!
