Lets put things into perspective:
Intel Core i9-9980HK in Macbook Pro 2019, 8 core, has Geekbench score of 1513, 6960.
Intel Core Ultra 7 258V 2200 MHz (8 cores) (Lunar Lake) 2719, 8749
A18 Pro in iPhone 16, 2 performance cores, 4 efficiency cores, 3440, 8478.
So A18 is about as good as new Intel Lunar lake CPUs. And those are in notebooks, right? Does anyone complains?
So A18 is more than capable to run macOS, also multitask hard, also play games. It mostly depends how much memory it gets. I hope for 16GB, so Apple intelligence will be able to run there. Anything lower just doesn't make sense.
Best thing we got from AI is more memory :-D
