--- Comment #5 from Sven Arvidsson sa@whiz.se 2012-07-22 20:26:38 PDT --- There should be a way to check the engine clock to see if it's running at full speed:

# cat /sys/kernel/debug/dri/0/radeon_pm_info

You'll need debugfs mounted first.

There was some talk on Phoronix about another APU running with very low clocks, could be something similar here perhaps? http://phoronix.com/forums/showthread.php?72046-E-450-graphics-performance-i...
