3770K + QuickSync: 9 sec
3770K @ 4.9: 36 sec
3770K: 47 sec

Transcoding an H.264 DTS 1080P trailer (150 MB) to MKV x.264 w/ 5.1 AC3 using HandBrake:
3770K @ 4.9: 30.66 fps
3770K: 24.71 fps

As you can see, the HandBrake encode is barely enough for realtime viewing of the transcode.

Handbrake uses multiple cores but the test was done with transcoding to x.264 which is very CPU intensive. MakeMKV may not actually be transcoding the video stream but simply remuxing the existing video into an MKV container.
