AMD equivalent to Intel i5-661 for low wattage build

I am very interested in building a low wattage machine, specifically I would approximately follow this article:
http://www.tomshardware.com/reviews/25w-performance-pc,...

However, I have always been a bit of an AMD guy and I wonder if there are equivalent low voltage, low wattage AMD processors of approximately the same performance specs to the Intel i5-661 stated in that article.

Any assistance greatly appreciated...

Probably not. The best cost effective solution is the propus 620 undervolted to about 1.0 volts. Some will do it. The 605 is a 45 watt quad core, but sells for around $150 outside the usa and only runs at 2300.

my phenom x4 620 never goes over 1.15volts even at load, so im sure u can undervolt the crap out of one

Problem is that the One you are looking at is a 32nm based part and AMD has nothing equivalent to that.

In fact I think the only thing that gives the same performance is a Athlon II X4 but that uses more power than the Core i3 661.

yeah but on stock voltage my PhII can reach 3.8 ghz, which means it doesn't need all that voltage. Thats why i under volt mine. The 620 can probably be undervolted further though since it has a lower clock.

I sitill doubt your X4 Pheom II will use less power than a dual core Core i5 thats on 32nm and a second gen HK/MG.

OK, thanks for all the info and recommendations. I think I'll stick with the Intel i5-661 then...

$200 that amd wont see, forgive me, l have failed you

please do not penalise me by asking more than $150 for the 1035t for i will be unable to buy it

Its not about what company gets what money, its about getting the person what they are looking for. If he wants Core i5 661 performance and power usage specs, AMD has nothing equivalent to that at this point.

When they do, it will be a different story.
