How did Apple Silicon get 50% faster in three years? – Daniel Lemire's blog

How much is SIMD actually useful in general computing ? I can see it being useful for stuff like graphics, video, audio and maybe AI. For other general purpose computing like browser rendering or word processing or spreadsheets the impact will be much lower.

Apple went wide, not deep. I believe even the A series were wider than normal. Also that MMU overhead must be a killer for everyone else.

Answer might be in the comments on the page: Apple has access to the best TSMC nodes.
