TLDR: The new MBPs are for people who need very high CPU and graphics performance, such as video editors. Regular people are probably better off waiting for the redesigned M2 MBA.
I think the design of the M1 Pro/Max vs the M1 chips tells you everything you need to know.
The M1 has 4 performance cores and 4 efficiency cores. This gives you a good balance between power and battery life.
M1 Macs are more than fast enough for the vast majority of people and give them real-life full-day battery life.
The M1 Pro/Max on the other hand has only 2 efficiency cores and 6+ performance cores.
So it’s optimized for high performance at the expense of battery life.
It has 25% less battery life compared to the M1 MBA and 35% less than the 13” M1 MBP.
In practice than means the MBA can get 8-10h of real life battery and the new MBP will likely only get 5.5 to 6.5h.
I think that’s a significant loss and definitely worth considering.
The CPU gains are also primarily in the multi-core and not in the single-core performance.
Most people’s workflow doesn’t come even close to fully utilize the multi-core performance of the M1, let alone of the M1 Pro/Max.
So they will get a lot of performance, that they will never use at the expense of battery, size and weight.
Of course there are other benefits, such as graphics performance, MagSafe, extra ports, bigger display, promotion.
I firmly believe a lot of the same benefits will come to lower-end models like the MBA in the future.
But right now the new MBP is the only way to get them.
And you need to decide whether these benefits outweigh lower battery life and increased weight.
I really hope the next M2 MBA will have the same battery life as the current MBA, but with a bigger screen, magsafe and the option for 32gb ram.
That would be the perfect machine for me.
