The 24GB unified memory is a really nice upgrade (the M1 MBA has 8GB upgradeable to 16GB). The CPU/GPU upgrades are predictable and wlecome but the memory is huge. A lot of development isn't CPU bound but is memory bound or at least can really benefit from more memory. This upgrade makes the MBA an entirely viable dev machine for many workloads. I have a MBP (Intel) but it's expensive. Getting a viable machine for $1…

The biggest question I have is whether it has WiFi 6E or just WiFi 6 (2x2 80 MHz like the original M1 MacBook Air). That's the one thing that's kind of gimped it for me—if I could get more WiFi bandwidth, especially with the ProRes decoding built into the M2, I might be able to edit 4K video over my network wirelessly for the first time. Would be amazing. To be clear, I still think the M1 Air was the best portable la…

From the specs: -802.11ax Wi-Fi 6 wireless networking -IEEE 802.11a/b/g/n/ac compatible Both same on the Pro and Air M2.

> Appple always leads the way with wireless chips for the last 15 years, and they don't disappoint again.

I mean, those specs seem to say that it doesn't support Wi-Fi 6E.

I doubt Apple will allow you to configure up to 24GB on a MBA though - they’d likely want to reserve that to the MBP which has active cooling and can sustain peak performance.

Edit: as comments pointed out, I’m wrong - thanks for the corrections.

Earlier quoted context omitted.

M2 does not hold a candle to the M1 Pro or Max, don't worry. Every improved spec is much better in the M1 Pro/Max.

Yeah but my guess is soon the M2 Max will be revealed. Its probably already developed, they just need to wait six more months to reveal. Clearly apple is able to jump straight to the M2, but they are releasing M1 to maximize profit.

Didn't the M1 come out in november 2020 and the M1 Pro in October 2021? That would be closer to a year than 6 months. I actually would not be suprised if it took even a little longer and if they went with a more advanced node on TSMC to get both, architecture improvements and miniaturization improvements.

Only 18% CPU performance improvement.. looks like we are finally getting diminishing returns.

This was on the same manufacturing process as the M1. There's generally a bigger boost when moving to a smaller process. But yes, there are diminishing returns, especially when you look at single core performance. Power efficiency and transistor counts are still increasing decently.

18% is pretty good for the same process. So all these gains are from microarchitectural smarts only? Or a case of Apple presenting fab gains as their own?

For Air too: https://www.apple.com/macbook-air-m2/specs/

> Configurable to: 16GB or 24GB

Store is updated too, 16GB upgrade is 200$ and 24GB is 400$.
