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.
