That article (and most of the M1 coverage) seems to missing the major design tradeoff made by Apple: theyâ(TM)ve optimized for CPU performance by holding GPU and memory on board in a true unified architecture, allowing them to simplify the design (which likely is why theyâ(TM)re getting good yields at 5nm), and benefit from faster RAM access. Its a very smart tradeoff that speaks to how most people use their laptops, and certainly how most Mac buyers were using their laptops. And yes, it will be possible for them to create models with more RAM and faster GPUs, but it will inevitably be more expensive and slower from a manufacturing standpoint.
So for a Mac buyer, this is absolutely a slam dunk: because those limitations were true anyway for Intel-based Macs: you had limited memory and gpu configurability, and the higher end configurations came it super high cost. However it remains to be seen whether Apple can produce high end configurations for gaming, data science, and photography power users that are price competitive with what we can get from AMD right now. Not saying they canâ(TM)t do it, but its silly to compare the M1 to high end chips quite yet. And even if Apple do succeed, itâ(TM)ll be a bittersweet sign for us PC hobbyists, because it probably will mean other manufacturers will follow this path of unified architectures that will mean less flexibility and choice for all of us.
