Lets bring back an old thread:

Quick test with the 2x2.3GHz G5 running a 3.10 beta (so any improvements to power management in the past 5.5 years does not apply).
Idle: 211W compile: 215W standbye: 2.3W
Needless to say this won't return to daily usage anytime soon....
Got a 2GHz PCIe and stand by is 2.7W which is similar to the AGP
Haven't really seen a difference between idle and use on this one, but there is this:
Radeon HD3650 -> 191W
Radeon R5 230 -> 170W (note, this card did not work with 3.19)
Giving how hot the 3650 was when I removed it I have no problem believing it using >30W (assuming the R5 is at least 10W).
All this with the 6600LE still installed.
Are the savings (up to 45W) from running the CPU at just 2GHz, improvements in HW or the 2nd core sleeping "better" than the 2nd CPU in an AGP?
Also noticed that the CPU stays in the 40s (with limited testing) while AGP and the iMac start there creep into the 50s even when idle and can easily reach 70° under load.
Power consumption under OSX (idle) is about 127W and in OF 170W (with the R5 installed) so there still some room for improvement.
