Today I performed a benchmark test with lastest MediaCoder iPhone Edition (which has improved support for Intel MSDK), by transcoding the same 720p H.264 MKV file to a MP4 file of iPhone 4 profile, respectively with encoder of x264 (fast preset) and Intel MSDK (balanced preset). The two times of transcoding result in video with near visual quality. The difference in transcoding speed and CPU utilization is somehow significant. With x264 encoder, the CPU utilization is near 100% and the overall speed is about 3.4x (versus playback speed). With Intel MSDK encoder, the CPU utilization is near 50% and the overall speed is about 7.9x, which is 132% faster than using x264.

MediaCoder iPhone Edition Benchmarks (Intel MSDK vs x264) (Stanley posted on April 7th, 2012 )

New benchmark mode added (Stanley posted on November 7th, 2008 )
A new task mode, benchmark mode, has been added since build 4210. In this mode, MediaCoder can be used to benchmark your hardware with media transcoding based on the your transcoding settings. During the process, the media content will be transcoded as in normal mode. The difference is there is no file created on hard drive and a benchmark result will be shown on the end of the procedure.
The steps to perform transcoding benchmark are as simple as following:
- Add files used for benchmarking
- Set up transcoding parameters
- Set task mode to “Benchmark”
- Click Start button to start benchmarking
