Sure. We don't know if the next MacBook Air is already an Apple Silicon Mac. They might do a speedbump from from the current Ice Lake Air to a Tiger Lake one. It would come with some very nice benefits — faster CPU, much faster GPU, Thunderbolt 4, Wi-Fi 6, PCIe 4 (which could mean a much faster SSD).
Well, they essentially catch up, roughly, with Apple's A13. It's not a 1:1 comparison, though; they draw more power, but also require less clock.
Compared to AMD, though, these seem to be about 30% faster in single-threaded performance.
The 16-inch MBP, if it does get another Intel chip, will likely get Rocket Lake-H next.
The 16-inch MBP uses 45W chips; these are 15-28W chips. Not powerful enough; not enough cores.
Tiger Lake-H (which hasn't actually been announced yet) could be an option especially if Apple wants to do a 16-inch MBP without discrete GPU again, which I'd be quite interested in. But they probably won't bother. Instead, they'll go with Rocket Lake-H, which will have similar features, but at 14nm. Much weaker integrated GPU, but more cores; possibly up to ten.
Just because it can run iOS apps doesn't mean it "mostly runs" them.
