>Surely all those server farms aren't built off GPUs right?
Yes they are, but it's not the same GPU's you can buy to put in your PC. If you watch some of the nVidia presentations, you'll see that they're super huge, and they're making them bigger and bigger each time.
nVidias market is no longer really focused on consumer GPU's. They're more so in the business of designing custom systems for big businesses that need datacenters and software solutions for training and analyzing all kinds of stuff with AI.
