People keep talking about differentiating between Intel and Apple Silicon Macs, but that’s missing the (well at least one) point. Apple doesn’t want to differentiate. Apple’s intention here is for this to be utterly transparent to most of their target market. Average users don’t know or care what’s inside, just that it’s faster or whatever other functional change there’ll be just as with any “normal” purchase or upgrade.
The first Intel iMac looked almost identical to the G5 iMac it replaced. Likewise the rest of the range.
Maybe they’ll change the screen size of the 13” to 14” like they did for the 15 -> 16. But that had nothing to do with any architecture change. And even if the 13 -> 14 change includes an architecture change, it will be just timing and not in any way related.
These new Macs won’t be any more different on the outside compared with the Intel ones than any other cosmetic or design upgrades have ever been.
Don’t forget with superior thermal Performance and better iGPU Apple could easily design a 14” screen into something that is roughly the same size as the existing 13” model. I’d suggest that they might also wish to put a bigger battery into it too if they want to make a headline feature of a significantly improved battery life in what’s likely to the the big selling mac SKUs.
And the point I’m making here depends on how much Apple need to differentiate the intel model from ARM ones in store.
Ultimately it could be a moot point if intel CPUs in laptops are going away within 2 years but I’m just a bit concerned about buyer confusion in store. Giving Mac buyers a size upgrade to switch to ARM seems like a good move as we can expect no intel redesigns now.
