Re: And about to fall off a cliff
I doubt they will be priced lower. That's not Apple's way. If they are faster than Intel versions, Apple is not going to also lower the price even if they're saving money. And they may not be, especially on the first generation, since they would have sunk a lot of money modifying their architecture for Macs, especially higher end Pro line machines.
They are not only doing Apple designed CPUs, but also Apple designed GPUs across the whole line - no more AMD GPUs on the high end. I'm more skeptical of them beating that mark with their GPUs since they haven't been designing those nearly as long as CPUs but I guess we'll see.
