Subject: AMD Dual Core vs. Quad - Power Management

Been running a few tests and an AMD motherboard booting 2.6.25 from flash uses 0.33 amps if the CPU is a AM2 Athlon 6000. But if I used a Phenom Quad core CPU 9550 it pulls 0.55 amps.

In theory the 9550 should pull less because it's a lower TPD and the phenom processor is supposed to be smarter about power management.

So - why is the Phenom pulling more power? Is it because power management software for the Phenom isn't updated yet?
