Is it? When they could be having you running an even more powerful model on a $50k machine they sell by the pallet-load to enterprise consumers? We already see RAM manufacturers abandoning the low-end market in favor of server support. It's not clear to me that Nvidia sees personal GPUs as their best long term investment compared to selling millions of server-farm class machines
Selling to individuals can be a hugely more robust predictable business, the problem with selling by the pallet load is spiky revenue that can also quickly fall off a cliff if larger customers stop buying. The other problem is sales negotiations driving down margins for bulk buyers etc. Consumer hardware is a very attractive market in lots of ways, just look at Apple.
You mean a $500k machine, or a $15M rack... the costs have gotten unimaginably large from the lens of just a decade ago.
