First, WELCOME ABOARD NEWBIE!!I think M1X is just a an extension of M1 and not a groundbreaking new chip. That'll be M2.
Anyhow there'll be enough work behind thermal and performance optimization for the Pro models and that's something to look for.
Will Apple announce them during WWDC next month? I need to make a purchase decision soon.
I expect,M1X, or other named variant, I think M2 is next year. There is so much they can do to/with the M1, before they will move to anything called “M2”. My thoughts, I’m holding out for WWDC, my needs are modest,(still rocking with a 2013 MBA), still ,at 73, my next will be my last, so M2 has my name on it.
Lastly, this is a very well run Web Site, you will enjoy it, a wonderful source of news/views. Lots of thought provoking views to make you think. ENJOY!
