In the first wave of new AMD processors with Zen 5 architecture, we took a closer look at a Ryzen 5. The results show many improvements (in speed, in efficiency, in cooling, …) led by unprecedented single-threaded performance. But in terms of the multi-threaded one, it’s still well behind the rival Intel Core i5-14600K CPU, albeit with much better power consumption. Gaming performance? Sometimes strange.
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)
Build from: https://github.com/BtbN/FFmpeg-Builds/releases
Command line: ffmpeg.exe -i “park_joy_2160p50.y4m” -c:v libsvtav1 -rc 0 -qp 55 -preset 6 -f null output.webm
Superb review. Especially concerning energy efficiency, idle power consumption and idle temperatures – you are the only ones that got so many useful info!
