It's no secret that Apple's M2 series processors are a pretty minor improvement over the M1 series. Expect much bigger improvements in the M3 series which will likely be using TSMC's 3nm process (and then probably only minor improvements again for the M4 series). It seems that Apple's ridiculously impressive consistent year-on-year gains up the M1 were in large part possible because they were behind the state of the…
Apple’s M1 chips already offered improvements compared to their previous generation Intel chips, and Intel hasn’t exactly been innovating in the last 2 years. By all accounts, they have been ahead of Intel, at the very least. I’m not exactly sure how Apple was “behind the state of the art” and has caught up. Can you explain?
The M1 was when they caught up. They were behind the state of the art (of laptop/desktop chip performance) with their A series chips starting with the A4. They gradually caught up over the course of several years to the point that when they released the M1 chip (which was really not that different to the A15) they were slightly ahead.
