Do they even need to, at this rate?
they don't need to do anything, but why not add a little bit of power and leave intel in the dust rather than keeping pace
or even more to the point, why not differentiate the lineup instead of selling a tower that is pretty much the same performance as a cube or even a laptop
is it that they only care about power efficiency and won't add any power, or that they've hit some sort of wall that more power won't overcome?
