Does anyone has good info on Athlon 64 X2's power consumption? (not TDP :P)
So far I've only found data for the 4800+ and 4200+, but they weren't as informative as I'd like ;)

OK, I'll answer my own question. I've found a site which states the power consumption of the 4200+, and it's at 9.6W idle and 54W load.

24 W idle and 86 W load for a 4800+, which gives
22 W idle and 79 W load for a 4200+ (not compensating for less cache).

I saw it at CplusE.com.

2 x Prime 95 draws more power than their load, can't explain idle though.... Cool 'n' Quiet maybe? I don't trust that idle number, how can it be identical to the 3200+?

Don't the 90nm single core processors idle to 10+ W. I remember reading about that somewhere here, maybe someone can confirm that.

Xbitlabs and Anandtech had those from memory... xbitlabs being the more comprehensive review from memory. Yes, the wattages were 10-15W depending on core revision.

I would imagine the X2's would idle something like 20W with CnQ enabled going on those numbers, unless the second core can be shut down completely, in which case they'd be similar to single core wattages.

Amazingly power efficient compared to the PentiumDs....

Beats me... I guess then that the lost circuits' numbers are more accurate.

Quote:
Cool 'n' Quiet will work on a whole chip basis, rather than each individual core, so if you load one core, both cores will increase their clock speed to reflect the additional load placed on the CPU.
