Well, there were some rumors for a while stating that Zen4 was PCIe 4.0 only but, between that roadmap and the rumor of RDNA3 cards supporting PCIe 5.0, they can be put to rest.
I wouldn't bet on Phoenix being more efficient than Apple's chip, but we've seen that they are better all around performers and I doubt that will change soon.
Oh, and since AMD says that Dragon Range will have a higher core and thread count than any other "mobile gaming CPU", that means that there will be a 16 Zen4 mobile processor to beat Intel's 12900HK with 8+6 cores/24 threads.
