So wait... the next iPad Pro and MacBook Pro will share the same chip, according to this simplified table? If that's the case then erm... no thanks. I kind of expect something beefier in an actual work machine.
The text below the chart in the first thread post says.
"... n contrast to Kuo's prediction, today's report claims Apple's first Arm-based Mac will be a
super-lightweight 12-inch MacBook, codenamed "Tonga," that will launch by the end of 2020. ..."
Apple doing a "one or two port wonder" MacBook rebirth wouldn't be all that surprising. Especially, if they left off Thunderbolt in this rebirth also. Put their "generation 4" butterfly keyboard on it and float that "thinnest of thin " system out there once again. That system really wouldn't be that much different than an iPad Pro (which pragmatically supports two ports now when extra fancy keyboard is attached. One for keyboard data and one external board. )
IMHO, I suspect Apple is going to want to 'prove' the MacBook wasn't the 'wrong path' and use Apple Silicon to take another whack at it with more electronics flexibility internally.
That isn't necessarily the same Mac SoC that would go into a MBP 13". Apple can get a "beefier" SoC the same way the A14X is bigger/beefier than the A14. Just add bigger system cache and more GPU cores of same basic design family.
(or GPU cores turned on versus off if they don't run into package size issues. But probably different die in different package like the 14X is off the baseline. Bigger system cache can perhaps crank the clocks a bit higher too on the CPU cores (without having to shift to different microarchitecture. ) )
Apple could be doing three closely related SoCs.
MacBook ( no Thunderbolt. And just use excuse didn't have it before as to why they skipped it here again. Mac Boot support as an option but pretty close to the 14X die if not a 'feature a , b, c' turned on/off separation. )
MacBook Air ( bigger die and bigger package , 2 Thunderbolt port ( one discrete controller so wider PCI-e lane support ) , Bigger GPU core count (but not max ). )
MacBook Pro ( same die but bigger package, more PCI-e line pad/pins out to flush out more ports, higher clock count , Max GPU core count for this family of GPUs. )
Not gonna place another bet on Apples ecosystem for an "improvement" I was never asking for.
Apple has been on the Captain Ahab trek after the "thinnest of thin" laptops for a long while. Mac specific silicon is exactly what they need if they want to continue that epic quest. Apple knows that the large bulk of their laptop buyers don't want this, but there is a large enough subset that do and Apple wants to do it.
People shouldn't completely "freak out" at the first Mac that Apple ships with Apple Silicon. It is highly unlikely that it is going to be completely represent what the rest of the Mac line up is going to be constrained with. More likely it will be the better match silicon for that specific product (not for the whole line up. Other systems will get better matches to them. And that is also going to a take a decent amount of time to roll out over the whole line up. )
It won't be very surprising though if Apple keeps one of the Mac SoC pretty close to the iPad Pro's. It would be a way of doing much higher volume of the exact same die. The iPad Pro has zero processor variation in the new product line up ( 11" versus 12.9" screen .. exact same die). Apple adding another product to crank even higher volume on that die would entirely within their common practices for component reuse. Other Mac products would share SoC dies between themselves too. ( but the very bottom edge of Mac performance range, overlapping with the iPad Pro probably isn't a big deal. )
