The big navi will need to be 30%+ faster than the 5700 XT in order to even compete with the 2080 TI, let alone "topple the 2080TI with ease".
And when you compare 2000mhz OC, come on. OC the 2080 and beat the crap out of the 5700 XT right? Apples vs apples, the 2080 is faster overall than the 5700 XT.
80+ CU card does not and will not exist. AMD can right now even with navi not make it more than 64 CUs. And I expect they will reserve that for their professional cards as they have so far.
Navi doesn't have the same CU limitation that GCN had, word is they can and will make a 80+ CU card, I do not see why this couldn't be the case, the only thing that will limit something like that is power usage targets.
Also the fact you are missing with the overclocked 5700XT matching the 2080 at stock is that the 5700XT is a 2560sp card and a 2080 is a 2944sp card (and lets not forget the pricing difference between the two of them either, in Australia, the cheapest 5700XT goes for $629AUD and the cheapest 2080 is $1049AUD, and the cheapest 2070 Super is $929) its besting a 384sp gap with immature drivers (Turing has had 10 months of driver optimizations thus far, and Nvidia's cards generally come out of the gate with most of their performance on tap anyhow).
Lets for a moment entertain your idea, that Navi has the same limitations as GCN (even though it has been designed from the ground up to alleviate all of GCN's short-comings..), a 64CU card will still be at or above 2080Ti levels of perf, if a card with 24 less CU's is at stock 2080 levels already...just going from a 64CU Vega64 to a 60CU Radeon VII already nets a 30% perf increase, and that isn't with overclocking the two (People are getting the VII to 2200Mhz+ with power play table mods, and I know that was an apples to oranges comparison, but it goes to show what should happen with a proper ISA for Navi, and 24 more CU's), so I think a 64CU RDNA 2.0 card with unlocked power play tables should easily best a 5700XT by 30% (especially with factors like Wave64 coming into play when new consoles release and games are specifically coded for it, and just driver maturation in general).
