Of course nothing forces them to be ready within 2 years but alas, that's what Apple said they'd do. I agree the M2 numbers were not amazing. I guess after the big M1 shock it's hard to follow up with something that comes even close. You can't get similar gains like the transition from x86 to an integrated arm based SOC brought, doubly so when there's no substantial process node improvement (N5 -> N5P is a minor optimization). In the end they mostly bought better performance with a bigger die and increased power consumption. I'm pretty convinced they'll need N3 for the next jump but even that wont be on the level of the Intel -> M1 step. The revolution has happened, now it's all about evolution. BTW if Apple wants to increase the prices of the Pro macbooks like they did with the M2 Air due to inflation then they better justify it with some good gains. The big changes in terms of hardware redesign already happened last time.

Intel and AMD seem to have both returned to the Pentium 4 days of chasing performance via increased clock speeds and power draws.

  The report you quoted and linked to is about the A15 and not the M2. The M2 is based on the A15 but from what I've seen it does use quite a bit more power (~30%?) than the M1 when loaded. Anandtech did not analyze the M2 yet as far as I can see.

    As previously noted, those core designs are used in both the A15 and the M2. Just as the same cores were used in the A14 and M1. Using more power overall comes from adding additional GPU cores and other non-CPU core functionality.

      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.

        We'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.

        I 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.

Are you European? The price of the M2 Air did not increase. The USD price was exactly the same as for the M1 Air. Both debuted at $1199. The price went up in Europe because of a drastic reduction in the EUR/USD exchange rate.

  The euro is not doing great, but the dollar is falling as well.

    The dollar is not falling. It has been extremely strong against any standard world currency basket. So strong it hurts exporters.

      Actually the dollar is falling as well (in real purchasing power) due to inflation. It's doing quite a bit better at the moment compared to e.g. Euro. One factor could be the increased interest rates. Why would I keep Euros and get still nothing when I could get at least a little bit on the USD. Also the war in Europe does not help their currency.
