Cray’s boss Peter Ungaro whose outfit makes supercomputers based around both Knights Landing and Nvidia gear has hinted that Chipzilla gear is gaining traction.

The second generation Xeon Phi product, codenamed Knights Landing, comes as a stand-alone processor and another one which will be released as a co-processor later on. All this stands in the way of Nvidia’s cunning plans in the market.

Ungaro, the company has a "substantial amount of business" that relies on both Intel's Knights Landing Xeon Phi part as well as Nvidia Tesla P100. He says he has significant orders for both.
But, he added that orders for systems based on Knights Landing actually exceed the orders for systems that use the Tesla P100. In other words, Knights Landing is already cleaning Tesla’s clock.

Motley Fool thinks that at the moment the market is big enough for both of them  Nvidia has reported that its datacentre related sales were up 63 per cent year-over-year. But we can expect Chipzilla to start getting more Chipzillish as it start’s bumping into Nvidia’s sales teams.

It might also start getting interesting when ARM chips start making an impact.
