Xeon Phi is a family of x86 many-core microprocessors designed by Intel since 2012 for supercomputers and workstations primarily aimed at scientists and researchers. Those processors are based on Intel's MIC Architecture. Xeon Phi differs from other GPGPU and many-core processors in its unique quality that it retains almost full compatibility with existing x86 software and libraries allowing those processors to tap into the extensive x86 ecosystem.

Knights Hill
- Main article: Knights Hill
Announces on November 18 2014, Knights Hill was planned to be fabricated on their 10 nm process. Severe delays with their 10 nm process has caused them to push the architecture all the way back to 2018. In late 2017 Intel finally announce that they had cancelled the architecture altogether in favor of an entirely new microarchitecture aimed at exascale computing.
