Now it's time to see if the reduced VCore does good on your power-bill. While we did not have much hope with the dual and triple-cores, the quads look much more promising.
As you can see the efficiency rate went up quite nicely.
As we have proved AMD CPUs are quite nice for under-voltaging. Power consumption comes down, especially with the quad-cores. Of course, to build an HTPC you need a board that does support under-voltaging. We can only hope companies see a market in this and do introduce mainboards capable of reducing Vcore. And if you are not into overclocking, you can have at least the same performance while keeping your CPU cooler and shaving of some bucks of your power bill.
