It's a lot simpler than the mental gymnastics you're performing here.
AMD said they would have plenty of supply, unprecedented levels from the past.
Today, the 9070 and 9070XT are mostly unavailable. The few places you can find one, the prices are inflated by 50% or more.
So, if they had sold an unprecedent amount of release GPUs, that would mean there would be a lot in use, correct?
So that would show on the Steam survey, right?
Well this survey answers that. No, they never had major supplies and never had a decent follow on to initial supply. They only have two models, and *neither* of them rated on Steam. I believe to rate, they need to have > 0.1%, which means neither model had more than 1/4 the supply of 5070s.
AMD has once again shown that they are masters of hype, and much of the tech influencers just follow along because that's what gets them clicks.
