“But when the memory controller moves back onto the CPU die and takes the GPU with it, that’s going to give an instant, one-time boost to the overall platform’s performance and efficiency. In the case of both Intel and AMD, this boost should be large enough that, if you can hold off on your next laptop upgrade until next year, you should. These kinds of discontinuities, where a major, disruptive repartitioning of the standard system architecture drives a one-off performance boost, are quite rare. They’re worth holding out for if you can manage it.”
