The graphs are titled performance/Watt. So what I understand from the graphs (taking desktop as example) is that the fastest speed grade of Conroe will deliver 5 times the performance/Watt of the fastest speed grade of Northwood (what was that? 3.0 GHz?).
Their own graph confirms this, as Smithfield runs at about the same clock speeds as Northwood (let's say 3 GHz), but with significantly higher TDP (let's say 100 Watt versus 70 Watt). Assuming that Smithfield has perfect scaling (in number of cores), performance per watt would be 2 * 70/100 = 1.4, which is about the number of Smithfield on this graph.
For the hypothetical example of comparing DC Opteron with Smithfield, just start with the observation expressed in many reviews that the fastest Intel dual core is slower than the slowest AMD dual core. Let's say a top speed Smithfield is about a 1.8 Ghz DC Opteron. Compare the Smithfield at 100W with a 55W DC Opteron 265 HE (the low power version): 100/55 =1.82. With these assumptions, a 265 HE would get 1.4x1.82= 2.5. Conroe will have a two times higher performance per Watt number, i.e. Conroe will be twice as fast as a dual core 1.8 GHz Opteron. This may be not so far (20%) from the fastest dual core of AMD in 2H 2006.
