What bits of M1 are rushed? What's your basis for saying that? This is a derivative core of a now very solid core microarchitecture. Does their new hypervisor implementation have bad errata, or their x86 emulation sub-par, or something?

The power, memory, IO interfaces or possible periphery around slightly higher thermal power headroom could be at a less mature point though I suppose.

M1X is for Macbook Pro and larger higher TDP computers isn't it? I don't really follow, how is this related to smartphone market?

I am very interested to see higher power headroom, more cores, and bigger IO and memory etc. regardless of the process it's on, surely it would allow for some decent performance gains.

It will be interesting to see which way they go with their CPU program now that it's getting more devices now sharing same/similar core.

On one hand it would make a lot of sense for this M1X to retain the same process and practically the same core (and much of the IOs) in order that logic and physical designers have mostly done with it and most of the work goes into putting the next core on the next process.

The other line of thought is that it is beneficial for a known good core to be ported to the next process to better characterize it and tweak and tune your physical design and circuits etc.

I could see it going either way, I don't know details of economics and benefits of different approaches to know what is more likely.
