I feel like this article really missed the mark. The RTX 3090 vs consoles is not a realistic comparison. The 3090 is clearly not the next generation of the 2080 ti, it is closer to the Titan cards. Nvidia is at fault in this confusion, they are obviously trying to blur the lines between titan and their consumer cards, no doubt to push people that are on the fence to make the leap. Sure, you can game on them, and Nvidia is pushing that aspect more this generation, but these cards clearly are for more than gaming.
This article is the equivalent of a comparison between a sports car and a race car. Sure, you could drive the race car on the street, but the value of the car is in making money on the track. Comparing the price for performance between a mustang and an F1 car would be nonsense, and so is the article.
The RTX 3080 is the flagship consumer card. If we want to compare next gen consoles vs next gen PC gaming, that is the comparison that should be made.
