x264 HD Benchmark 4.0

Posted on Friday, Apr 08 2011 @ 10:22 CEST by

This is the improved version of the x264 HD Benchmark 3.0 benchmark which had become a standard CPU benchmark for Tech ARP as well as many other hardware enthusiasts.

The new x264 HD Benchmark 4.0 ups the ante by using the latest r1913 x264 encoder as well as other changes under the hood. This makes the x264 HD Benchmark 4.0 the new best tool for testing the full capabilities of modern multi-core, multi-threaded processors.

Do note that due to the changes, the results from x264 HD Benchmark 4.0 are NOT comparable with results from older versions of the benchmark.

In addition to the release of the benchmark, we will be compiling benchmark results for this new version. So please contribute your new benchmark results to this project!
