M2 Air to M5 Air keyboard feels exactly the same. Performance in another league though, even for every element of everyday usage, things just snap into action so quickly and apps open so fast
By another league, you mean M5 compared to M2? Yeah, the M2 was a solid improvement over the M1 but from the M2 to the M5 there have been a couple of substantial jumps, from the M2 to the M3 thanks to the new process node and the introduction of Ray Tracing, and from the M3 to the M4 regarding CPU and Machine Learning capabilities.
Then the M5 is a moderate improvement across the board, with a big boost (30%) on the GPU.
The general gains on the M5 are achieved with a clock increase thanks to the refined process N3P, bigger cache (like on the M2), and better ML/AI capabilities thanks to the Neural Accelerators on the GPU. But I still consider the M3 to M4 jump bigger overall, maybe because I’m biased towards CPU performance…
But yes, on the path from M2 to M5 every step has carried significant gains in one or another direction, making the M5 a whole other league compared to the M2.
I expect the M6 to be similar to the M3 evolution, using the node shrink to achieve higher clockspeeds, and using a higher memory bandwidth for improved on-device AI. And then, the M7 will be heavily focused, according to leaks and rumors, in bringing the AI stuff to a whole new level, probably accompanied by another big GPU improvement. But that’s pure speculation in my part.
