Your second point is false. You’re simply making that up. In any event, as I said, TSMC 5nm gate pitch, metal pitch, min width, etc. is nearly identical to Intel 7nm.
As for your first point - what? If I can get the same performance from an Intel 7nm or a TSMC 5nm, why would the consumer care? At equivalent design rules, Intel’s processors simply can’t come close to competing at performance/watt with Apple’s.
