This is being marketed as a "server" chip... The only application I can see this doing well in would be low-energy markets. But even then I doubt it will be successful with all the advancements in ARM.
It's an 85-140W thermal envelope chip, with 16 very fast cores (iirc, AMD vs. Intel TDP). That's in a completely different planet to a 1W sluggish(ish) ARM core.
Or, slightly more to the point: Oak ridge is making a supercomputer using these chips. These are designed to be very fast. They are not designed to be low energy in the ARM sense of the word.
These are, iirc. designed to be used in visualised server (cloud) and other high compute environments.
