This is a test of the Intel Open Visual Cloud Scalable Video Technology SVT-HEVC CPU-based multi-threaded video encoder for the HEVC / H.265 video format with a sample YUV video file.
To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark svt-hevc.

Revision History
pts/svt-hevc-1.2.1 [View Source] Sat, 04 Jun 2022 07:05:31 GMT Long overdue for offering 4K video option in this particular test profile...
pts/svt-hevc-1.2.0 [View Source] Mon, 15 Mar 2021 07:05:16 GMT Update against SVT-HEVX 1.5.0 upstream, expose multiple encode mode options.
OpenBenchmarking.org metrics for this test profile configuration based on 1,348 public results since 4 June 2022 with the latest data as of 15 November 2024.
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 (SVT-HEVC 1.5.0 - Tuning: 10 - Input: Bosphorus 4K) 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 0.8%.
Does It Scale Well With Increasing Cores?
Yes, based on the automated analysis of the collected public benchmark data, this test / test settings does generally scale well with increasing CPU core counts. Data based on publicly available results for this test / test settings, separated by vendor, result divided by the reference CPU clock speed, grouped by matching physical CPU core count, and normalized against the smallest core count tested from each vendor for each CPU having a sufficient number of test samples and statistically significant data.
Notable Instruction Set Usage
