Well - they charged more at each price point because they were faster.
At some prices I think it wasn't enough to justify the extra cost from a price to performance ratio, but that doesn't seem like a reason to think they're bad.
It's possible I'm a little out of date on this, I only keep up to date on the hardware when it's relevant for me to do a new build.
Are you joking? How is it the same price point when they are charging more?
E.g. the bottom of this page: https://www.anandtech.com/show/14618/the-amd-radeon-rx-5700-...
At the lower price point nVidias line up is similarly crowded: https://www.anandtech.com/show/15206/the-amd-radeon-rx-5500-...
Either way, there would be no reason to group the 350$ and the 400$ card but not the 300$ and the 350$ card.
BTW, AMD definitely didn't always have a price/performance advantage, e.g. the nice scatter plots here from ten years ago (that I randomly found): https://techreport.com/review/19342/gpu-value-in-the-directx...
Just because company A makes the fastest card does not imply that company A makes the faster card at every price point.
