Intel Core Ultra 7 265K: Often more efficient than Ryzen 7 9700X

Video encoding

Intel Arrow Lake desktop CPUs have undergone a significant change on many levels. Aside from the new performance (P) and efficient (E) core architectures, they are now chiplet-based and have stopped using Hyper Threading, for example. At the same time, the power consumption is lower and the Core Ultra 7 265K CPU is often more power efficient compared to the competition. This even in games, which we haven’t seen before.

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).

Disclaimer: For big.LITTLE-based processors, the result is missing in some tests. This is because they didn’t scale properly with P cores and the achieved performance was too low. In such cases it is indeed possible to force performance on all cores, but this does not happen by default at the user level. To avoid creating the illusion in some cases that measured results such as those presented in the graphs are normally achieved, we omit them. However, these are a negligible fraction of the total set of test results.

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
