x264 OpenCL

This is a simple test of the x264 H.264/AVC encoder using OpenCL. If you wish to run the x264 test on the CPU, just use the x264 test profile rather than x264-opencl.

H.264 Video Encoding

OpenBenchmarking.org metrics for this test profile configuration based on 781 public results since 31 August 2014 with the latest data as of 7 December 2022.

Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded results. It is important to keep in mind particularly in the Linux/open-source space there can be vastly different OS configurations, with this overview intended to offer just general guidance as to the performance expectations.
