Apple has booked TSMC's initial production of the first next-generation 4 nm process node wafers according to Digitimes. The first chips to roll off the production line will be destined for Apple's Mac line, which of course includes its MacBook Pro models and iMacs.

even in 3nm can't create 64c CPU 128c GPU if not in 3D tech.
the imac is damn grandgrandfather in 2021. need a better newer design with this fantomatic M1Z/M2 processor with a decent TDP like 55/65W. if yeeeeeeeeeeeeeeeeeees I'll sold my kidney and install linux or windows in parallel desktop :p
It's great to see Apple starting to move forward and regain the cutting edge now they are leaving Intel behind. Touch screens in all devices would be A good step to make them relevant today. Apple and TSMC working together us fantastic.
