Also I thought Apple is adding a large slice of cache. When you look at the 3D-V cache on Ryzen for performance (+15%?), this has a large impact. And because they sell expensive stuff, they can afford to build expensive CPUs.

Cache doesn't matter for pure ALU efficiency though. I mean, I did tests on long dependent chains of FMAs, the only memory touched there are two internal registers.
