So, AMD plans to utilize TSMC's 7nm+ (EUV) process for their Zen 3 architecture and 5nm for their Zen 4 architecture. But how exactly will this compare with Intel's chips? Intel has been stuck on 14nm forever and only just released their 10nm Ice Lake mobile chips a few months ago which was quite underwhelming and offered less performance in some cases to their 14nm+++ (Comet Lake) CPUs, and are basically made irrelevant with Zen 2 on mobile now. But with Intel's 10nm+ Tiger Lake coming this year and 7nm chips coming next year, will AMD be in trouble? Intel's nodes are way denser than TSMC's nodes, but AMD is promising up to a 17% IPC uplift with Zen 3 (if rumors are to be believed), and Intel only managed to achieve an 18% IPC increase from 14nm to 10nm on Ice Lake, and that took them nearly four years to do.

These days it is very unlikely to see ANYTHING "drastic" happen in terms of gains. It is likely they will surpass Intel, but it is doubtful it will be major or drastic. Likely it will be the kind of thing that slightly moves them past in single core performance BUT when multiplied against all available cores offers, hopefully, a modest increast in overall performance.

Honestly, this is the wrong place to be asking those questions. They'd be better pursued here:

Most likely, it will be faster. There is no new architecture coming from Intel before AMD releases Zen 3, it will be another 14nm refresh from Intel without an increase in IPC or a decrease in power consumption, and since Zen 2 pretty much nearly matches Intel in single core performance and IPC as it is, any increase from AMD in those areas is likely going to push them past Intel in that regard as well as probably further widen the core/thread gap.

All of which, as usual, is only speculation, since we NEVER know anything, until we KNOW something. And that isn't until reviews of finished hardware are released. Anything contrary to that is merely guesswork.

ah I see, so AMD will most likely drastically surpass Intel in performance with Zen 3/4, but by how much? If Zen 3 is promising a 17% IPC uplift and Zen 4 is on a 5nm node, by around that time Intel would be on 10nm++ or 7nm. Recent rumors suggest that TSMC's 5nm node is going to offer 80% more logic density and Apple's A14 iPhone chip on TSMC 5nm is rumored to be faster in multi-core compared to a 6-core Intel i7 in the current MacBooks . So would the same scenario apply to AMD if they were to use TSMC 5nm on Zen 4?
