Xeon Phi has gained universal recognition from supercomputers for its powerful acceleration computing performance, which can be found in the Global 500 list. The US Department of Energy described Argonne National Laboratory's plan to build a new supercomputer "Aurora" with Xeon Phi, Completed in 2021.

China's Tianhe Superman has also used Xeon Phi, and won the world's first, and then the Americans could not stand it, it is forbidden to export to China, but our scientists are very competitive, the current rank of the mighty Taihu Lake light Have already realized the localization of the chip.

Socket type Xeon Phi

PCI-E expansion card Xeon Phi

Going back and say Knights Mill, still using Intel 14nm process manufacturing, the core number, frequency, bus, memory and other specifications have basically maintained the previous generation style, the two main changes isSupport for 32-bit floating-point QFMA (quadrature product and fuse operation), 16-bit integer VNNI (Vector Neural Network Instruction Set), which greatly enhance the AVX512 utilization and execution efficiency.

According to the official statement,The new generation of double-precision performance is cut in half, but single-precision performance doubled, variable accuracy performance quadrupled.

among them,Flagship model for the Xeon Phi 7295, 72 core 288 threads, clocked at 1.5-1.6GHz (acceleration frequency reduced by 100MHz), two cache 36MB, thermal design power consumption 320W (surge 75W), memory support six channel DDR4-2400 , The maximum capacity of 384GB, with up to 16GB MCDRAM.

320W thermal design power also hit a history of Intel processorsRecorded because the main reason is to relax the voltage and frequency constraints, increase production, while adding a new instruction set.

Xeon Phi 7285It is68 core 272 threads, Clocked at 1.3-1.4GHz, secondary cache 34MB, thermal design power250W.

Xeon Phi 7235Fall to64 core 256 threads, Clocked at 1.3-1.4GHz, two cache 32MB, thermal design power250W, memory support down to DDR4-2133.

Currently, Knights Mill offers socket processor style only, no PCI-E expansion card style.
