For your information, the new “Intel® Xeon Phi™ Processor” website has been launched recently! Please visit this new website here.
The Intel® Xeon Phi™ processor is a many core processor based on a modern Intel® Atom™ microarchitecture with considerable High Performance Computing (HPC)-focused performance improvements. It has 72 cores with 4 threads per core giving a total of 288 CPUs as viewed by the operating system. The cores are laid out in units called tiles. Each tile contains a pair of cores, a shared L2 cache, and a hub connecting the tile to the interprocessor interconnect.
Major architectural innovations include the addition of on-package MCDRAM, clustering modes and Intel® AVX-512.
