Not surprising. Given the state of the market right now, both AMD and Nvidia are selling out as fast as the fabs can crank them. With the crypto-craze, gamers can't get their hands on GPUs, so gaming performance is irrelevant, and if one company releases a new GPU that hashes the other out of the water, they won't be able to support all the demand anyway. Better to stick with your existing products as long as possible. Takes less manpower to generate a new GPU every 2-3 years than every 1-2.
