There's more to it than chip design though. There is the OS work to take advantage of the chip's new features. And designing new chip features to accommodate sw bottlenecks. Apple has very close collaboration between software and hardware engineering, while in the competitive space, those two things are not under the same roof. Makes it tougher.
True, and I don’t expect generic manufacturers to completely close the gap between them and Apple, but I do expect there will be enough to copy that we’ll still see a step change in PC performance.
