Even Higher Efficiency for Parallel Processing

Intel® Xeon Phi™ Coprocessor Block Diagram

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. You can use Intel Xeon processors and Intel Xeon Phi coprocessors together to optimize performance for almost any workload. Because both processor and coprocessor support the same software code and programming models, your developers won’t have to reinvent the wheel to deliver optimized performance.

Accelerate your innovation

The Intel® Xeon Phi™ coprocessor can dramatically accelerate performance for your highly parallel applications and help you push the boundaries of innovation and scientific.
