NVidia is limited by the number of chips they can produce.
If you can fab 1000 chips, and can sell some for $500 and some for $80000 what are you going to do?
The game GPU is at once profitable, but causes them to give up far more profits than they're gaining from it.
They're maintaining the game market to have multiple markets and not go all in, but it's strategic hedging at this point. When NVidia makes a gaming GPU instead of a data center GPU they are leaving money on the table in the short term since they're constrained at the fab level.
This almost seems like we need a strategic reserve for semiconductors- kinda like we have it for food, to prevent suppliers from throwing it away when they are suddenly able to sell something much more lucrative.
