Intel adjusted its roadmap to focus on high-performance exascale computing. Part of this .plan is scrapping the previously announced Knights Hill based Xeon Phi accelerators. The product line has been removed from the latest roadmap.

Intel will replace Xeon Phi with a new platform and architecture reports tweakers.net today, Intel makes note of this fact (albeit a little hidden) in this article. The exact reasoning behind the cancellation of Xeon Phi is vague, as well as specs on the new architecture.

Intel first announced Knights Hill back in 2014, it would be based on 10nm and would support the new generation Omni-Path-interconnects. Xeon Phi, if you can remember it, was a relative if the Larrabee GPU project and thus effectively, this would be the end of Intel's Larrabee GPU project.
