Media Encoding


Video Encoding

Our first media encoding test uses the latest CS5 software from Adobe. This software accesses all of the cores/threads available on our processors and is therefore an ideal application for media enthusiasts. To test performance we run a 1920×1080 file (custom recording) through the encoder set to 1080p 24 HQ using the H.264 Blu-Ray codec within the application.

GPU Assisted Media Conversion
Our second media encoding test takes a 4GB 1920×1080 file and converts it with Arcsoft Media Convertor 7 to iPad format with GPU assistance.

Music Encoding
Our music conversion test takes an 18 track lossless album and converts it using dBpoweramp into 128Kbps Mp3 format. dBpoweramp is a multi-threaded application which allows us to convert a track on each core/thread, at any one time.

In these tests we again see the gap in performance between the desktop 2600/2500K CPUs and the M17x with the lowest specification CPU. As before we could of course add a higher specification model during the purchase process to close the gap but it is worth considering, as an example, that 40 seconds to convert a full 80minute CD is incredibly fast and achieved on the slowest CPU option.
