unlimitedbanana, on about performance per watt. Intel cpu can be easily overclocked to 4.5ghz+ and still take less electricity. Point is the amd ios on the brink of its limits, intel cpu's are bought to be overclocked for high end users, or ofr people who don't care used at standard clock and low power consumption. Anyway the amout of joules required to do the same task.
On this shows 132 watt hours less required for 3770k over an amd fx8350.

On this shows how poor amd fx is once overclocked as the power consumption rockets up:

I mean seriously a 3570k at 5ghz takes 267w or a 3770k takes 244w at 4.8ghz or old gen 2600k take 313w oc to 5ghz or 180w at stock vs an amd fx 8150 taking 586w oc to 4.8ghz or 244w at stock.
To be fair fx8350 takes 213 stock and 364w at 4.8ghz. Either way all tese amd cpu's get embarrassed.

If amd get close to what intel have now in 2 years that would be incredible turn around. The most worrying thing is intel will target with haswell to half power consumption at same performance and they already showed one benchmark like this that 8w haswell performs same as 17w ish ivy bridge. Now considering they are double the performance per watt currently amd could be 4x performance per watt behind if amd don't wake up.
