They're actually a lot closer for a given level of performance right now. Look at the i7 vs Ryzen 5800X or 5900X, and the i7 is more efficient for lighter workloads.yes, as already noted.Intel "10 nm" is about the same as TSMC "7 nm". These "nanometers" are not actual sizes of the transistors or other features in the IC, and hence these numbers are not comparable across companies. So I don't think Intel has been "struggling" really that much: Intel and AMD are both at the same actual density currently.The one differentiator is circuit size - Apple and AMD have an advantage over Intel who has struggled to move to sub 10nm manufacturing. It is somewhat cloudy in that marketing has made it fuzzy what it means to do 7nm or 5 as Apple does. Advantages here are likely to be short term ones.
But it took Intel a long time to get to that "10," well beyond schedule. It resulted in some major leadership change at the company. And still it takes them double the wattage as AMD.
The issue is the i9 where to get that performance crown they went outside the efficiency envelope. And it's up against the 5950X which due to binning is usually more efficient than the 5900X.
I'm still really happy with my 3900X especially compared to what was out there at the time and overall AMD has strong points still. But Alder Lake is a pretty great achievement from Intel. The big question is how will it work with 15 & 45w mobile chips.
