x265

This is a simple test of the x265 encoder run on the CPU with a sample 1080p video file.

To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark git/x265.

Performance Metrics

x265 Git

H.265 1080p Video Encoding

OpenBenchmarking.org metrics for this test profile configuration based on 167 public results since 8 March 2019 with the latest data as of 8 January 2025.

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 (x265 Git - H.265 1080p Video Encoding) has an average run-time of 3 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 1.1%.
