It'd be nice if things worked like this.... But they don't.
The same logic would suggest that, if intel could make the core m7 at 4.5w, then they could've made a 20c/40t upto 3ghz cpu with 1920 (240 eus) core gpu.... at 45w! In 2015!
But they couldn't, because its not that simple.
I dislike apple, not a fan of anything, but I dislike apple, because every person who buys apple stuff, seems to only buy apple stuff, irrespective of its worth. The amount of businesses that really innovated and have been ruined, whilst customers go out and buy $400 watches that they'll barely look at after a month....
The M1 is incredible, I hate apple, but kudos, but its not as incredible as some seem to believe, the m1 macs have massive caveats, but still, with how much of a market share they have when producing the most un-innovating crap year after year, I worry of how much of a monopoly they'll get with a genuinely good product... :(
There is a silver lining. Apple is lazy, take a look at the imac. Fanboys we're "leaking" 32core m1x for that, what they got was an giant m1 ipad without a touchscreen.
Don't worry kiddos, they'll probably release a 12 core model for the mac book 16 and recycle the 8 core for 14. Because why bother spending money, when the peasants will give us their money anyway.
