Power-saving features were enabled for each processor at stock frequencies, but disabled for higher and more stable overclocks. We chart peak input watts during active idle, full Prime95 load, and throughout our gaming tests.
Our bench rig is way overpowered with the 80 PLUS Silver-rated Corsair HX1050. Gaming on these single-GPU platforms, we can assume roughly 87-88% efficiency, meaning the unit’s peak output was only around 185-285 W.

Although Intel’s Core 2 architecture wasn’t all too shabby in terms of energy consumption and efficiency back in the day, we can certainly appreciate the increased performance per watt the Ivy Bridge design enables. Take a close look at the E8400 and Q9550. The added performance secured by boosting voltages came at a steep increase in power consumption.

Also, amoralman, did you read this? It's basically assuring you that your C2D is still awesome as a budget processor.
Also holy crap on 1.45 vcore on the C2D
I find it shocking that my E6600(which I still hold in high regard, is far far worse than a 50 dollar Celeron. My mind is blown.
That said, today's quads have a more efficient and better architecture than those of yesteryear, and the 3570K is a popular choice for enthusiasts.
intel made all their leaps forward with this architecture, and killed AMD in the process. And has never really moved past it... 6 years on and it still stands toe to toe with the latest and greatest.
I'm not that surprised really.
i have both and the 3570k is significantly faster than an e6600, i always had problems with the e6600 not being fast enough for my taste, its a night and day difference between the 2
