What? https://www.nextplatform.com/2018/03/01/server-market-booms-last/What efficiency? What? What?! :-D
Again: what?!
Server CPU market is worth around $18bln yearly. AMD expects to get maybe 10% of that in next few years, so around $2bln.
Nvidia's revenue for 2017 was $10bln.
Short term - surely not. Seriously, the demand for GPUs is the same - no matter how many companies make them. If TSMC becomes a monopolist for GPU chips, they can choose who to work with. NVidia has higher margins, so it's likely they'd be paying more for chips. So in short-term going 100% NVidia would make sense.
Long-term is different, because of diversification. It's better to have more clients that make different products. This is a reason why staying with AMD makes sense... unless TSMC is already negotiating with Intel.
That's $18 billion a quarter (probably last year) & not annually! The sever market could actually top $100 in a year or two easily, where do you think Chipzilla's $6 ~ 7 billion (annually) in operating income from DCG came from?
