Succession
Knights Landing

Knights Hill (KNH) was Intel's planned successor to Knights Landing, a 10 nm many-core microarchitecture for research and supercomputers.

History

Announced in 2014, Knights Hill was originally planned to be delivered in 2016 and be manufactured on a 10 nm process. The architecture was also planned to power a number of supercomputers, including the United States highest-performance supercomputer, Aurora. Delays with 10 nm has pushed the product back to 2017. Eventually, in November 2017 Intel announced that Knights Hill would be cancelled:

One step we’re taking is to replace one of the future Intel® Xeon Phi™ processors (code name Knights Hill) with a new platform and new microarchitecture specifically designed for exascale.

Brands

Knights Hill was branded as 3rd generation Xeon Phi

Process Technology

Knights Hill was intended to be fabricated on Intel's 10 nm process.

Architecture

Intel released very few architectural details regarding Knights Hill.

Key changes from Knights Landing

• 10 nm (from 14 nm)
• 2nd Generation Omni-Path Architecture
