If the increase in power consumption comes from the additional GPU core, from increased frequencies in the CPU cores or other added parts to the chip imho is not that important for users (and depends on what they are doing). They see the system as a whole. They get x% more performance for y% more power usage. For the CPU x is smaller than y. This is totally normal when increasing frequencies.
Note: I'm not saying the M2 is bad. It's a very good chip indeed. All I said was it was not amazing. It was an iterational, yet welcome, improvement. And I think one couldn't expect anything amazing quite so quickly.
- GeekyBear 4y agoWe're talking about CPU core design. Would we say the Zen 4 core design is less efficient because AMD is going to start bundling an integrated GPU with Ryzen chips, or would we just talk about Zen 4 core power draw vs Zen 3? Apple's performance cores managed to improve performance while cutting power. What other iterative core design did this? It helps to remember that Apple isn't playing the performance via clock increases no matter what happens to power and heat game.
- eis 4y agoI guess that's where the misunderstanding comes from. I was not talking about CPU cores alone. Only M1, M2 as a whole. But I still am not sure if I can believe that the M2 CPU improved performance while at the same time cutting power. Can you link to some analysis? Would be very interesting. Though please not the A15 one, the cores are related but not the same and the CPUs have big differences.
- Maursault 4y agoApple hardware updates are always and only moderate incremental improvements, since the very beginning. Apple is reasonably predictable in this regard. It is unrealistic to expect a generational and exponential leap in performance or efficiency in any of Apple's hardware refreshes. That has never happened, and it likely never will. What happens instead is whatever model gets a little bit better than the last revision. The M1 was not a massive leap forward, but instead an impressive lateral move. Subsequent Apple Silicon chips will only be a smidgen better than the newest previous revision.

The jump from x86 to M1 was a boost because of TSMC's fab process compared to Intel's, yes, but it was also from the ISA change, leaving behind a lot of the x86 cruft.
