You don't have the process details to make that claim, so stop trying. Getting more performance with less area and power is an absolute metric of technical excellence.No. That could be called "product dominance" (if you really need to use this word).
Basically, you've just confirmed what he said: Intel and AMD make similarly good architectures and actual advantage (chip size and power draw) is provided by the node.
In other words:
Intel vs AMD: pretty much a draw
Intel vs TSMC: currently solid lead by the latter.
