Intel’s (NASDAQ:INTC) new Xeon Phi line of high-speed computer chips are being used in the world’s fastest and most powerful supercomputer, China’s Xianhe-2.
Xianhe-2, which translates as MilkWay-2, was just named the world’s most powerful computer on a list published twice a year ranking the world’s top 500 supercomputers. The computer contains 48,000 of the Xeon Phi chips in addition to 32,000 Intel Xeon chips that are more commonly used in regular computers. Xianhe-2 offers more than double the performance of the top-rated supercomputer on the November 2012 list.
The difference between the Xeon and the Xeon Phi chips is in the number of processor cores, which handle complicated computing tasks. The original Xeon chip has between one and eight of the processors, while the new model has twelve. The Xeon and Phi chips work together to break up calculations into small pieces, passing information from the Xeon to the Phi chips to complete tasks faster.
