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
