Intel Xeon® Phi™ Coprocessor Family
The Intel® Xeon Phi™ coprocessor - illustrious performance per watt, built to perform brilliantly on your greatest challenges. The only thing more amazing than the Intel ® Xeon Phi™ coprocessor is what your research will do with it.
A Single Programming Model
While the Intel Xeon processor E5 family remains the preferred choice for the majority of applications, Intel Xeon Phi coprocessors provide more efficient performance for highly parallel applications. They include many more and smaller cores, many more threads, and wider vector units. The high degree of parallelism compensates for the lower speed of each individual core to deliver higher aggregate performance for workloads that can be subdivided into a sufficiently large number of simultaneous tasks. You can use Intel Xeon processors and Intel Xeon Phi coprocessors together to optimize performance for almost any workload.
Intel® Xeon Phi™ Coprocessor Family Key Specifications
- Up to 1.2 teraflops double-precision performance
- Single programming model for all your code
- Flexible usage models to maximize your investment
- Ideal for highly-parallel, vector-intensive, and memory-bound code
Is the Intel® Xeon Phi™ Coprocessor right for me?
You can use Intel Xeon processors and Intel Xeon Phi coprocessors together to optimize performance for almost any workload. To take full advantage of Intel Xeon Phi coprocessors, an application must scale well to over onehundred threads, and either make extensive use of vectors or efficiently use more local memory bandwidth than is available on an Intel Xeon processor.
