The latest PC numbers show Apple with < 10% of the laptop market. That can't sit well with Apple. They're going to try to move them while they are ahead of Intel.
I'd bet, instead, Apple prices the standard configs aggressively (for Apple), but then wallops the BTO (extra cores == $$) users, because people who really need 20/40 cores will realize they can afford it.
It's hard to tell what Apple will do. I think that the better long-term approach would be to keep prices low to build marketshare, sell services and the ecosystem. The short-term approach would be to make maximum profits. It may be possible to do both at the same time by making the entry models really cheap and the high-end systems really expensive. I have a friend that always just buys the high-end configuration of electronics products.
Apple will have the most powerful laptops out there for a while, in terms of CPU. I do not think that they will get there with GPU though - certainly not in the form-factors that they like to have. But they will have the fastest CPUs and I expect that they will have pretty good thermals.
What will really be crazy is when we get iPhone 13 devices to measure the IPC improvement over the iPhone 12. If it's in the 20% to 40% range, then Intel and AMD are going to have a really hard time catching up.
