From my understanding the problem isn't with the architecture, but with manufacturing. AMD is about to release 7nm CPUs manufactured by TSMC, meanwhile Intel only recently sorted out its 10nm issues and 7nm is scheduled for 2021 if everything goes well.

IIRC, Intel’s 10nm is measured differently than TSMC’s 7nm, so they are actually more or less at the same node. By some measurements, Intel 10nm is actually smaller than TSMC 7nm. I think some significant part of AMD’s manufacturing advantage also comes down to the fact that their “chiplet” architecture is proving to be easier to scale than Intel’s less modular designs.
Density is measured differently by different fabs, i.e. you can't do direct nm comparison, same as you can't do direct MHz comparison between different CPU vendors. Supposedly Intel 10nm and other 7nm are roughly on par.

My understanding is that Intel's manufacturing lead is basically gone now, and with Zen 2 so too will their uarch lead (IPC, AVX throughput, ...) disappear.

You can tell who the AMD fanboys are because they keep repeating this line even though it gets pointed out every time that the different fabs measure density differently and that Intel's 10 nm process is on par with TSMC's 7 nm.

The difference is that Intel's 10nm process doesn't exist in a meaningful sense.
Please don’t use characterizations like “fanboys”
Except TSMC is also on track with their 5nm plans for volume production in 2020 while Intel has been stuck on 10nm for years with "promises" of 7nm ...
TSMC 7nm is production, Intel 10nm is (still) vaporware :P
Nowhere is his comment he said Intel 10nm is better or worse than TSMC 7nm. Not sure who is being fanboy here. At the time of my comment there are three comments repeating the same fact of how fabs measure density differently. I would say Intel fanboys is getting defensive.
