AutoMKV x264 Encoding

Website: Doom9

We tested x264 compression using AutoMKV version 0.97.1 and x264 to to compress a 1.1GB DVD VOB file into 350MB MP4 file using a two-pass encode and we used a 112kbps LAME encoder to compress the audio. The whole process is dependent on both single and multi-core performance and the entire encoding time was recorded.

There's quite a shift to using MKV or MP4 wrappers for x264 content now, especially for movie content and those in the large anime fansubbing community. x264 doesn't have the same SSE enhancements as DivX 6.8, but the benefits of extra cache and better memory performance should still show notable improvements.


The 7850 Black Edition affords a slight but notable improvement over the previous 7750 BE, and both are very much faster than the stock clocked Intel E5200, however when we drop overclocking into the equation there's an eight percent improvement for the 3.1GHz clocked 7850 BE, but the Intel E5200 at 4GHz is still over 30 percent faster than this.

Handbrake H.264 Encoding

Website: HandBrake

Our test uses Handbrake - an open-source, GPL-licensed, multiplatform, multithreaded video transcoder, available for MacOS X, Linux and Windows - to encode a high resolution MPEG-2 video using the H.264 codec. This primarily tests multi-threaded CPU and memory subsystem performance.


For Handbrake video encoding the AMD 7850 BE, 7750 BE and Intel E5200 are pretty evenly matched at stock speeds, and overclocked the 7850 Black Edition is around ten percent faster, but again the overclocked Intel E5200 nearly squeezes out a 38 percent faster time.
