Last time I checked the TDP/frequency curve of Apple's chips was unimpressive [0]. If you crank it up to 4Ghz it's going to be as "bad" or even worse than a Ryzen CPU in terms of power consumption per core. There is no free lunch. Mobile chips simply run at a lower frequency and ARM SoCs usually have heterogenous cores.

>but this is an architecture that the PC market needs to be scared of.

This just means you know nothing about processor performance or benchmarks. If it was that easy to increase performance by a factor of 3x why hasn't AMD done so? Why did they only manage a 20% increase in IPC instead of your predicted 200%?

Isn’t this a RISC vs CISC thing though? AMD and Intel use a lot of complicated stuff to emulate the x86 instructions with a VM running on a RISC core. Apple controls hardware and software including LLVM so they compile efficient RISC code right from the get go. It’s their vertical integration thing again.

You got a point in the optimization part, it's difficult to compare both chips when you're running on completely different OSs, specially when one of them ruins a specially optimized OS like ios

The closest it could get I think would be running a variant of Unix optimized for the Ryzen.

Don't just downvote me, explain. I'm asking because I'm interested. Why is my hypothesis wrong?
