When total power consumption of the systems are measured the E7200 draws about as much (or as little if you like) power as a X2 4850: computerbase.de When you look at performance however the E7200 beats the 2.5GHZ AMD CPU hands down being 25-50% faster depending on the actual benchmark (synthetic tests: 27%, office applications 52%, multimedia 30%, games 26%, overall 33%). Now try to figure out how this translates into performance per watt ratios and what it tells us about value for money. The AMD needs to be cheap because it is slow. "The Core 2 Duo E7200 (2.5GHz) is £75 and 65W. That is a 53% premium at a higher TDP."

Re: I've heard it is the worst of the options. Hard to make a judgment when you've only reviewed one option. I addressed this and other points about the ExtremeTech review here: Message 24828452 Re: The 45W Athlon X2 4850 (2.5GHz) is listed at just £49 (incl. VAT) at dabs.com. At that price the only Intel alternative is a Pentium Dual Core E2200 (2.2GHz) at 65W. The Core 2 Duo E7200 (2.5GHz) is £75 and 65W. That is a 53% premium at a higher TDP. Granted, it's a higher price. But this is clearly an example of a situation where actual TDP and measured power are two different things. Intel may choose to call the E7200 a "65W TDP" part in order to use the same thermal solution as their other Core 2 products, but I showed you links in my previous response that clearly showed the E7200 dissipating 3W in idle and 19W under load, as measured from the socket. Here is the article again: digit-life.com They didn't test the 45W Athlon 4850, so it's hard to say how it compares. But clearly, it can't be much better than what Intel's offering today. It just depends on whether you can afford that extra 26 pounds in price difference. I think for the performance, it's worth it, but YMMV.
