I'm glad to see that the PPC is at least trying to keep up with the x86. Ever noticed that the MHz advancement of x86 CPUs is at a stead pace, while PPC makes huge leaps? It's one of the reasons why, when everyone thinks PPC sucks, suddenly it's back in the running again. The performance of this chip will surely be better than any existing x86 chip.
The big problem is that when the 970 lands, the performance of the x86 may already have crawled far ahead of it again.
