this would be "great" provided it goes against and slaughters 1660 super i.e more memory faster all around while not being much more (if any) extra power required.
I seriously doubt they (AMD) will bother as though they likely would want to fill their product offering stack up, what about all the AIB and shelf space for everyone (given Ngreedia and their heavy heavy hand on any "hinting" they want to support anything other than them and them alone?)
We are still waiting on RX 5500 and 5500 XT (announced back October .. though THEY were only meant for OEM product) would be "great" for someone like myself on a tight tight budget but wants "modern" performance to pair with my current "high end" Ryzen 3600 vs continuing to use my very old (still works wonderful after 4 odd years) Radeon 7870 "ghz" edition ^.^
as long as the price is "fair" has the performance (as well as drivers) certainly not much more (preferably less) power use (as well as noise levels) they will and would sell as many as they can make, 192 mem bus done right is "perfect" where 128bit holds potential back big time
IMO
plenty of trees need new Radeon and AMD underneath them this holiday season (^.^)
