An aspect ratio of 2.35:1 is used with letterbox bars at the top and bottom of the 16:9 image. The average video bitrate is around 34Mbps but frequently peaks above this around 42Mbps.

This said, all the AMD CPUs performed reasonably well with maximum CPU usage reaching a shade over 50% even with the least powerful AMD Athlon II X2 255 processor. MKV Playback: Our test file was a 1080p .mkv file which was taken from a 1080p source and converted into this format. Content on this page requires a newer version of Adobe Flash Player. MKV playback is a little more CPU intensive than Blu-Ray playback, accounting for the increased CPU usage across the board. Once again, the i3-530’s maximum CPU usage was below that of all the AMD processors. Pages: 1 2 3 4 5 6 7 8 9 10 11 12 13 Share On
