Intel and Netflix's SVT-AV1 gains up to 40% performance boost, AMD Ryzen will benefit too
Back in 2019, Intel and Netflix collaborated on creating a software-based (CPU) encoding implementation of the AV1 codec. As such, SVT-AV1 was born where SVT stands for Scalable Video Technology. SVT was developed by the former, and as the name suggests, it is designed to be highly scalable in order to get the best out of multi-threaded processors and multi-socket CPU systems. And while SVT was developed by Intel, AMD's Ryzen and EPYC chips also do quite well in SVT-AV1 benchmarks.
Following that, SVT-AV1 was adopted by the Alliance for Open Media (AOMedia) as well and the latest version of the codec brings a massive performance boost of up to 40% under certain situations. The official release notes claim a 30-40% speed up when encoding in higher-quality presets. However, it is unknown if the testing was done on Intel or AMD or an average of both.
Meanwhile, the faster (lower fidelity) presets have a modest 1-4% improvement as well in their Bjontegaard delta rate (BD rate). For those unaware, the BD rate helps to measure and compare the compression efficiency of various codecs.
The full changelog of the SVT-AV1 version 1.6.0 is given below:
In related news, preliminary support for the next-gen AV2 codec is already beginning to surface.
