Based on the data in the article, it looks like Nvidia cards are holding onto more value than AMD cards.

It makes sense. There's still a fairly large gamer demand. Gamers prefer Nvidia cards over AMD cards. Gamers were priced out during the crypto boom but are probably buying up used mining GPUs for gaming right now - thus, preventing a full collapse in prices.

Nvidia cards have lost ~8% in value month over month compared to 20% for AMD cards.

I expect prices to fall at a faster rate next month, once the pent up gamer demand has been satisfied.
