Quick fact: if you overclock a Radeon VII and cool it properly, it will trade blows with a 2080, and beat it in some titles. The Radeon VII was a cut-down Instinct workstation card. It only stands to reason that if the VII could compete with the 2080 in some areas (albeit water cooled and OCed to the moon), and that card is a cut-down version of crap they just had laying around that didn't make the cut for Instinct, then they could conceivably have the ability to release a 2080TI competitor.

And there is the problem sadly. AMD will always dominate in the price vs performance field. But as you say, cool it properly "a la" buy a waterblock, means your product now costs $100 more. It then loses that price vs performance to quite an extent.

Furthermore, OC the hell out of it bumps your electric bill (if you pay it at all) and yearly costs loses even more of that value you chose AMD for.

An RTX2080Ti is 30-40% faster than a 5700XT on average.
If you made a 64CU version of the 5700XT that's 60% more cores.
If you gave it 16Gbps chips and a 384-bit bus width (Same as RTX2080Ti) that's 70% more theoretical bandwidth than 5700XT.

So even counting for practical losses and lower clock speeds a 50% gain over the 5700XT is pretty doable. Die size should be around an RTX2070 in that scenario, which is still a good chunk larger than a Radeon VII but not exactly out of this world.
Seems reasonable.
Hope it happens.

I don't see a card faster than a 2080ti as a problem or the fact Nvidia will hit back with something faster.

That sort of performance at a cheaper price will do many things for us.

Maybe it will be hot and loud (ok so definitely) but if it weren't for AMD I wouldn't have a 2070 super now.

So long as they are not looking to charge the ludicrous prices Nvidia are, they are going to gain market share, Ray traced or not.
Bring out something that offers 2080ti performance (non raytraced) at around £700 and they will be the heroes. Its still between £1100 and £1300 for a 2080ti and just to add, knowing AMD, they won't put there raytracing algorithms in a walled garden for those willing to pay for it, they'll offer it out for free. I mean why not when your tech is powering all the next gen consoles

DigitalFoundry calculated about 405mm^2 for the Xbox Series X die shots released by Phil Spencer by the way.

This confirms AMD can produce 7nm chips at the size required for a 64CU Navi model/"2080Ti killer", for reference Radeon VII was 331mm and 5700XT was 251mm.
