Intel Core I9-13900K and I5-13600K Review: Raptor Lake Brings More Bite

And it is important to remember the AMD IOD is still on N6 or similar to current Intel 7 2nd gen. ( i.e On I/O level AMD and Intel are on the same Node ) Even if Intel was on Intel 5 or TSMC N5 equivalent it still likely wouldn't be using similar power as AMD.

So I am actually surprised at how well AMD Zen 4 is doing. It used to be if you want MT you go with AMD, at the expense of ST. Now this is no longer the case.

If you care about energy efficiency, just buy AMD Zen 4.

I think this mix of processes is testament to the fact analog is not scaling, and high speed IO has a lot of analog/phys. So having an IOD on 3nm would cost more and probably consume similar power, at least for the phys. Of course you will always get sub systems on that die that would benefit, but overall its likely a net loss.
