Wouldn't the reverse be -10 percent every year? Because no, that isn't true. And CPU's don't improve by just 10 percent. AMD's FX CPUs just are not very good and bulldozer to piledriver little performance increase is proof of that. Intel goes by a path called Tick-Tock. Tick's are small performance increases, like Ivy Bridge. Sandy Bridge was a tock. So, Ivy Bridge was 10 percent better than Sandy bridge, while Nahalem to Sandy Bridge was around a sixty percent increase. So, Ivy to Haswell could also be a 60 percent increase. We don't know with GPU's yet, but the 690 to the titan is a 10 percent increase. Hover, a 6970 to 7970 was a big increase.
