At the ISC 2016 International Supercomputing Conference held recently, major companies have launched a new generation of computing solutions, China's Sunway Taihu Light with 4 260 nuclear Shenwei processors topped the TOP500 champion, NVIDIA launched a Tesla P100 acceleration card based on the PCI-E program, Intel Although lost orders in China's HPC market, they announced their 14nm process, codenamed Knights Landing Xeon The Phi processor is officially shipped, with up to 72 cores and 288 threads, integrated 16GB of eDRAM cache, TDP245W, and a price of $6254.
Intel announced the shipment of a new generation of Xeon Phi processors
The Knights Landing architecture Xeon Phi processor was announced as early as the ISC conference in 2014, and since then, HPC-related events have been shown every year, until this year's ISC conference Intel announced the official shipment of Knights Landing.

According to official sources, the Knights Landing architecture of Xeon Phi mainly has four models, namely Xeon Phi 7290/7250/7230/7210, of which the latter three can be shipped immediately, Xeon Phi 7290 will not be listed until September this year, and then Xeon Phi 7290F/7250F/7230F/7210F will be listed in October.

Let's briefly talk about the specifications of these four Xeon Phi processors:
Xeon Phi 7290 is the flagship of new products, 72 cores, 288 threads, frequency 1.5GHz, support 384GB DDR4 memory, while the processor itself integrates 16GB eDRAM cache, TDP 245W (Fabric edition plus 15W), priced at 6254 US dollars, equivalent to 41113 yuan.
Xeon Phi 7250 is 68 cores, 272 threads, frequency 1.4GHz, support 384GB DDR4 memory, while the processor itself integrated 16GB eDRAM cache, TDP 215W (Fabric version plus 15W), priced at 4876 US dollars, equivalent to 32054 yuan.
Xeon Phi 7230 is a 64-core 256 thread, frequency 1.3GHz, support 384GB DDR4 memory, while the processor itself integrated 16GB eDRAM cache, TDP 215W (Fabric version plus 15W), priced at 3710 US dollars, equivalent to 24389 yuan.
Xeon Phi 7210 is 64 core 256 threads, frequency 1.3GHz, support 384GB DDR4 memory, while the processor itself integrated 16GB eDRAM cache, but the integrated memory frequency from 7.2GT/s down to 6.4GT/s, TDP 215W (Fabric version plus 15W), priced at 2438 US dollars, equivalent to 16027 yuan, it is the most cost-effective of these Xeon Phi processors.
As for the Knights Landing architecture, I will not repeat it here, we have written in detail several times before, you can refer to the previous article:

This one comes with additional Fabric networking technology
Pay attention to the WeChat public account exp2006 of the super energy network, the original scientific and technological information is wonderful.
