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.
To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark x264-opencl.
Use with caution this test profile is currently marked Deprecated.
* Uploading of benchmark result data to OpenBenchmarking.org is always optional (opt-in) via the Phoronix Test Suite for users wishing to share their results publicly. ** Data based on those opting to upload their test results to OpenBenchmarking.org and users enabling the opt-in anonymous statistics reporting while running benchmarks from an Internet-connected platform. *** Test profile page view reporting began March 2021. Data updated weekly as of 1 September 2024.
Revision History
pts/x264-opencl-1.9.1 [View Source] Mon, 15 Feb 2021 12:47:31 GMT Mark as deprecated.
pts/x264-opencl-1.9.0 [View Source] Sun, 31 Aug 2014 11:15:49 GMT Initial commit of OpenCL-specific version of x264 encoder. Complementary to x264 test profile and thus start it at x264-opencl-1.9.0 versioning to avoid confusion.
Performance Metrics
Analyze Test Configuration:
x264 OpenCL 2014-08-30
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.
Based on OpenBenchmarking.org data, the selected test / test configuration (x264 OpenCL 2014-08-30 - H.264 Video Encoding) has an average run-time of 2 minutes. By default this test profile is set to run at least 5 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 1.2%.
