Seems Nvidia have made sure this time that the price differences between cards will be more in line with performance maybe. 3090 was twice the price for 15% more performance. The very hefty 4090 price gives loads of room to adjust prices more in line with performance gain so maybe no card looks as good a value as the 3080 was. And that supposedly was a 'promotional' price.
I'll feel sick if one of the 4080 devices delivers most of the 4090 performance for loads less, but looking at that pricing it's 15% of the £1700 MSRP of the 4090, looking like price/performance ratio maybe much more in line this gen, meaning that 4090 owners wont feel as sick as 3090 owners.
4090 is a beast of a card - cant see needing much else for 4k for a while. 5000 series will be for high end VR, multi monitor high res displays for simmers and the like where a 4090 still cant deliver res&refresh fps.
To pull 3080/6800XT and above owners away from their very capable cards - they had to deliver something with whopping performance. If AMD manage to release in the same performance ballpark as Nvidia then it is evidence that they have been drip feeding performance all along as how would two competing companies manage to stay so close performance wise each time?
