>> They have little presence in HPC/AI

Huh? The Xeon Phi is used regularly in the industry. Nvidia is dominant but to call Intel's presence small is very odd.

Did you miss that Intel's stopped developing the Xeon Phi's?

I did, since that's not true. Knights Landing is discontinued and Knights Hill is suspended, but they are continuing development for DOE Aurora and other projects and targeting 2020-2021 - while existing stock is used regularly and the used market is plenty active. I get a lot of use out of the x200 line.

It is more or less true. Xeon Phi is being replaced by regular high core count Xeons with HBM MCM on one end, and a traditional GPU on the other. While the brand name lives on, it's not at all a continuation of the product line.

A lot of the Xeon phi usage in HPC is due to non technical reasons (e.g. Intel subsidies).

The memory bandwidth is just crushingly bad.

I guess? I mean it is not poorly represented in the Top500 and Top50 for "crushingly bad" memory bandwidth, I'll say that much.
