Power savings from i7 920 to 3570K

post #1 of 3
Thread Starter 
What kind of power savings would I realize from making the upgrade?

For reference, I idle @ 140 watts and prime95 load @ 280 watts. The drawback I realize is I depend on my blck mostly for the overclocking and the bclk doesn't throttle back during idle. The newer SB and IB chips don't depend on the bclk and mostly depend on the multi for overclocking, so my idle power savings should really add up.

I'd say you'd save 100W on load and maybe 60W or so idling assuming stock.


If both OC'd to max it'll be more like 150W load and 100W idle.

Mine is at 4400MHz w/ 1.21v and no VGA.

The full system is drawing between 35~60W during idle and 140~155W under load in Prime95 AVX.
