This is a multi-threaded test of the x264 video encoder run on the CPU with a choice of 1080p or 4K video input.
To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark x264.
OpenBenchmarking.org metrics for this test profile configuration based on 242 public results since 28 May 2022 with the latest data as of 28 June 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.
Based on OpenBenchmarking.org data, the selected test / test configuration (x264 2022-02-22 - Video Input: Bosphorus 1080p) has an average run-time of 2 minutes. By default this test profile is set to run at least 3 times but may increase if the standard deviation exceeds pre-defined defaults or other calculations deem additional runs necessary for greater statistical accuracy of the result.
Based on public OpenBenchmarking.org results, the selected test / test configuration has an average standard deviation of 0.4%.
This benchmark has been successfully tested on the below mentioned architectures. The CPU architectures listed is where successful OpenBenchmarking.org result uploads occurred, namely for helping to determine if a given test is compatible with various alternative CPU architectures.
