What's probably the most interesting thing is the iGPU that's coming with the 10th gen CPUs on the 16" laptops. This is going to be the first update to the iGPU in a couple years. It should help greatly in video editing as the quikcsync performance should be lot better.
I believe you're confusing it with 10nm CPUs (U) that have the newer Sunny Cove arch with the newer iGPU version. These 10th-gen H series is not any different from 9th-gen H series, same iGPU as usual, they're just clocked up.
So the same second as I order a brand new 16 inch from Apple? Oh well, guess I'll return it...
You won't notice much of a difference and Apple won't be bumping it any time soon. Too little of a difference to justify it.
This is true, but Intel can’t change the Laws of Physics. They are starting to hit brick walls in terms of how much power they can pack into a laptop CPU.
Except AMD just destroyed Intel's highest 45w/90w (9880/9900HK) CPUs with a 35w Ryzen 4900HS CPU with better multi-thread pref and identical or better single-thread pref.
Read or watch the reviews. Majority are basically saying AMD's mobile Zen 2 lineup the biggest generation leap in pref in a decade.
Except that their A-series only supports one and only one I/O port. Not even thunderbolt. No discrete GPU connection possible. If want to build a one port Macbook follow on ( iBook or iPadOSBook ) they have got something.
But if look at Intel PCH chip Apple really doesn't have much of anything comparable. Well they just buy an PCH like chip from ASMedia like AMD does. They could but .... no connection for that either on the A-series. Can they add all that stuff ? Yes . Do they have copious spare time and resources? .... hmm A12x -> A12Z and a warmed over iPad Pro early 2020. Maybe not.
The A14 is going to be extremely good at being primarily an iPhone SoC. The A14X will likewise going to be extremely good at being primary an iPad Pro SoC. Most of Apple's ARM powered offerings though are done with "hand me down" variants. A subset of Macs could work with "hand me down" variants too but would highly likely not be sufficient to actually cover the functionality of most of the Mac line up.
Omission is not evidence that they don't have anything for a laptop CPU with more diverse use case. You're not going to see a full PCH on any public SoCs from Apple because there's no need to include it. Apple is paying and optimizing for every square meter of their CPUs. Every single SoC such as A, H, W, S, and T series are all custom-designed for their own uses. Apple didn't simply port A series to their watches or pods either.
You're comparing a 7w-optimized custom mobile CPU to a full 45w general purpose Intel CPU? Apple is not going to simply port A series to the laptop. They will have a custom design of their own to scale up to 25w/45w and they'll either license or buy anything they don't have time for. Kuo already suggested that Apple is getting USB4 stuff from ASMedia (https://www.macrumors.com/2020/03/26/kuo-several-arm-based-macs-2021/).
I don't see Apple beating Intel at this game but they don't need to. Apple is about to switch to 5nm, they just need a good enough SoC that is optimized specifically for macOS with Metal-tuned graphics, CoreML, etc. They can remove anything else that's in Intel CPU that they don't need and pack them in with more cores or something else.
As for 2020 iPads, it's not a new CPU. It's just a hardware stepping bump to enable the last disabled GPU core with 6gb of RAM by default. That's not evidence that Apple has ran out of ideas, they just don't need to because the CPUs are too fast for the ecosystem anyway. No one is crying out for more pref in the iPad Pros, it's the software that's the problem.
