NVIDIA forces you to buy significantly more expensive cards that perform marginally better if you are using them for datacenter use. They try to enforce not letting businesses use consumer grade gaming cards. I assume this is so cloud providers don't buy up all the supply of graphics cards and make it hard for gamers to get decent cards, like what happened during the bitcoin craze.
Sure sorry I realize now the point I was trying to make doesn't match my wording. They do care about selling to gamers but availability to gamers is not in anyway why they are forcing more expensive models of essentially the same cards on the HPC and server market. It's all because they can and the business market is able to bear the cost. Now if they found a true competitor in that market, I think this pricing model would fall apart fast.
