I'm running Ubuntu 11.04 (Natty), with an i5 2500k (not overclocked) and a z68 board.
I'm trying to encode DVD quality VOB files to the iPhone preset in Handbrake, but in mkv format. I'm currently getting about 105 fps average and it takes me somewhere between 15 and 20 minutes to complete. This definitely isn't bad performance, but based on these reviews and benchmarks:
I should be getting twice what I see. I tried duplicating their tests as closely as possible, the only exception may be that they're using Windows and I'm using Linux.
Both reviews are using Handbrake for their tests, as am I. Because Handbrake doesn't support QuickSync/GPU encoding, it's of no consequence that there is no QuickSync support in Linux.
Can anyone think of reasons why I'm see "degraded" performance?
