There are some known performance problems with UVD. I don't believe we know why
it is slower than fglrx yet. Maybe something subtle related to UVD setup.

Tiling is also disabled for UVD surfaces at the moment. This slightly reduces
throughput, especially on GPUs with little memory bandwidth (such as APUs).

I have very similar config to your (3.11 + DPM + oibaf PPA) except HD 6670
instead 6310 - but vdpainfo output looks exactly the same. However, I cannot
confirm your issue. I am curious what is your
/sys/kernel/debug/dri/0/radeon_pm_info?

Mine:
sudo cat /sys/kernel/debug/dri/0/radeon_pm_info
uvdvclk: 7 dclk: 56000
power level 0sclk: 8 mclk: 10 vddc: 1100 vddci: 0
