Video encoding
The top model of the 14th generation of Intel Core (Raptor Lake Refresh-S) processors has outperformed everything that has come out for desktop computers so far. In speed, but also in power draw. On the one hand, the 6 GHz metric for single-threaded applications has been reached and the clock speeds are very high even under all-core boost, the side effect is that the Core i9-14900K’s power draw can sometimes spike up to 400 W.
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 585 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)
