Highly parallel processing to power your breakthrough innovations

Intel® Xeon Phi™ brand badge

Power your breakthrough innovations with the highly parallel processing of the Intel® Xeon Phi™ coprocessor. We’ve packed over a teraFLOPS of double-precision peak performance into every chip.

Peak Theoretical Performance

These charts represent processors' or coprocessors' theoretical peak capabilities for single precision computations, double precision computations, and memory bandwidth. The metrics provide a baseline for the raw performance capabilities of each part.

Accelerate your highly parallel applications with the Intel® Xeon Phi™ coprocessor:

    > Up to 3.6x higher peak single precision floating point operations per second (FLOPS)

    > Up to 3.6x higher peak double precision FLOPS

    > Up to 3.45x higher peak memory bandwidth

vs. 2x Intel® Xeon® processor E5-2670

Product and Performance Information

1. Software and workloads used in performance tests may have been optimized for performance only on Intel® microprocessors. Performance tests, such as SYSmark and MobileMark, are measured using specific computer systems, components, software, operations, and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated purchases, including the performance of that product when combined with other products. For more information, go to www.intel.com/performance.

2. Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See www.intel.com/content/www/us/en/processors/processor-numbers.html for details.

3. Different hardware architectures may require different source code. Results are based on Intel’s best efforts to use code optimized to run on all architectures and perform the same work. Future code optimizations may result in different results. Microprocessor-dependent optimizations in this product are intended for use with Intel® microprocessors. Certain optimizations not specific to Intel® microarchitecture are reserved for Intel microprocessors.
