Alex Deucher <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Severity|normal |enhancement --- Comment #1 from Alex Deucher <[email protected]> --- Please(In reply to comment #0) > My laptop (Lenovo Edge 11) has the Mobility Radeon HD 4200 Series chip > (RS880M) > (windows says it's a HD 4225) > > It consume with fglrx ~16W. (kernel 3.4.47) > With radeon (kernel 3.11-rc2) and power_profile=low ~20W > With radeon.dpm=1 (kernel 3.11-rc2) ~20W The power usage between DPM and profile=low should be pretty comparable on these chips. DPM just has the advantage of being able to dynamically change the clocks and voltage transparently when performance is required vs. having to change it manually with the profile code. -- You are receiving this mail because: You are the assignee for the bug.
