Video encoding
We’re wrapping up tests of the new Ryzen 9000 desktop CPUs. This with a model that once increased the number of cores compared to its predecessor, or a pilot model (Ryzen 9 3900X) from eight to twelve on AMD’s mainstream platform. Even compared to the Ryzen 9 5900X, the new Ryzen 9 9900X is more than twice as fast in some practical situations. This model is also the best when it comes to efficiency.
HandBrake
Test environment: For video conversion we’re using a 4K video LG Demo Snowboard with a 43,9 Mb/s bitrate. AVC (x264) and HEVC (x265) profiles are set for high quality and encoder profiles are “slow”. HandBrake version is 1.3.3 (2020061300).
x264 and x265 benchmarks
SVT-AV1
Test environment: We are encoding a short, publicly available sample park_joy_2160p50.y4m: uncompressed video 4096 × 2160 px, 8bit, 50 fps. Length is 500 frames with encoding quality set to 6 which makes the encoding still relatively slow. This test can make use of the AVX2 i AVX-512 instructions.
Version: SVT-AV1 Encoder Lib v0.8.7-61-g685afb2d via FFMpeg N-104429-g069f7831a2-20211026 (64bit)

I am wondering what is going on with certain tests where 9900x is inferior to 7900x. In particular, AIDA64 FPU Julia and Mandel. For instance, in Julia test 9900x only achieves 28% of 7900x’s performance…!? Does it have something to do with test versions (7900x was tested almost 2 years ago).
This also makes me to ask if there is a way to tell which cases are actually comparable? Is it possible to select only the exact same versions?
I assume that this is a consequence of non-optimization of the application (in this case Aida64) for given tests with specific processors, or rather their architectures.
