No, attractive affordable gpus are available. Nobody is buying them.
Nvidia knows its market.
Your wrong, AMD is not supply constrained.
AMD manufactured enough low end products to fill the channel and then some
rx6600 @ $239 last I checked:
That is the same price as the rx580 was sold back in the day. Supply is plentiful. Prices are right. Customers are not interested.
also:
rx6500 @ $160
rx6400 @ $149
AMD has effectively done that. Nobody is buying them.
That is not what the market is interested in.
gtx1080 msrp: $599
same performance today?: rx6600xt @ $329
buyers are not interested.
