@atpfm@mastodon.social the "mistake", from a Mac Pro perspective, Apple made was going with a monolithic architecture design as opposed to a chiplet architecture design.
AMD has been ruining Intel in the PC chip performance at all levels of the CPU industry in part *because* they chose chiplets as their design paradigm.
They have released in the last two years a couple of white papers that may be of interest:

@illustro@mastodon.social @atpfm@mastodon.social Apple's monolithic designs made sense, and scaled up to well to the Max. With the M5 Pro/Max, Apple is now on heterogenous chiplets, but Apple's not scaling multiples of them (I think it is just a CPU die and a GPU die). We don't know how they'll scale up to Ultra (or even Quadra... my preferred term), without designing NEW chiplets. With the M7 and M8 we'll see if Apple gets to multiple CPU dies and multiple GPU dies to allow true efficient scaling.
