I doubt Ryzen 4000 will match 10th gen parts at 5.3ghz, but I think it will be very close. I expect intel's single thread margin to shrink from a maximum of about 20%, to a maximum of about 10%, while AMD's margin in multi threaded workloads will grow by at least 10%. Some rumours suggest that biggest gains will be in FPU workloads, which could be interesting for scientific applications in particular. Modeling and stuff.
Depends on clock speeds though. Rumors are that Ryzen 4000 is about 10% faster IPC. If they can add 300mhz of additional clock speed too (boost clocks) then performance will match or beat intel everywhere, but from what I have read increases in clock speed are likely on base clocks, rather than boost clocks, and likely to affect EPYC and thread ripper rather than consumer parts.
I have also heard more rumors about 8 cores per CCX. A 8 core, single CCX CPU would be great for gaming, but even if that is true, AMD hasn't released a single CCX quad core part yet, preferring to have two CCX with half the cores disabled. Consumer 8 core chips would likely be the same.
So it seems like a modest upgrade for consumer, but we will see.
