Comment # 10 on bug 71448 from 
This is probably related to dpm and gpu clocks - if I run "vblank_mode=0
glxgears" in parallel with the benchmark the results are significantly better
for me:

w/o gears:

MPEG DECODING (1920x1080): 13 frames/s
MPEG DECODING (1280x720): 13 frames/s
H264 DECODING (1920x1080): 12 frames/s
H264 DECODING (1280x720): 13 frames/s

with gears:

MPEG DECODING (1920x1080): 77 frames/s
MPEG DECODING (1280x720): 118 frames/s
H264 DECODING (1920x1080): 51 frames/s
H264 DECODING (1280x720): 92 frames/s

Setting power_dpm_force_performance_level to "high" doesn't really work for me
in this case - AFAICS the driver resets it back to "auto" when the benchmark
starts, probably when switching to uvd state.
