Totally wrong.

Apple is using TSMC ~15nm process which TSMC calls "N5". N5 is just a name.

Intel is using ~18nm process which they originally marketed as "10nm" and now call it "Intel 7". Those 10 and 7 are only names.

Wrong. AMD uses TSMC's 20nm process which TSMC calls "N7". THis N7 is only a name.

And SMT has NOTHING to do with single-thread performance.

There is no 7 nm or 5nm anywhere.
