Delivers over a teraFLOPS (floating-point operations per second) of double-precision peak performance.3 1 5 Additionally, as compared with Intel® Xeon® processor E5 family-based servers, the Intel® Xeon Phi™ coprocessor delivers up to 2.3 times higher peak FLOPS,3 5 6 up to 3 times more performance per watt,3 7 and up to 7 times better performance on certain financial services applications.3 8
Applications can support both Intel® Xeon® processors and Intel® Xeon Phi™ coprocessors which use common languages, models, and familiar and standard development tools, so there’s no need to learn new languages or tools.
Leverage the compute flexibility of Intel® Xeon Phi™ coprocessors to either use with Intel® Xeon® processors to accelerate processing of highly parallel code, or create independent, high-performance compute nodes with their own IP addresses to run applications independently—unlike a basic accelerator.

Claim based on calculated theoretical peak double precision performance capability for a single coprocessor. 16 DP FLOPS/clock/core * 61 cores * 1.238 GHz = 1.208 TeraFLOPS.
Intel® technologies' features and benefits depend on system configuration and may require enabled hardware, software or service activation. Performance varies depending on system configuration. No computer system can be absolutely secure. Check with your system manufacturer or retailer or learn more at http://www.intel.com.
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.
Cost reduction scenarios described are intended as examples of how a given Intel®-based product, in the specified circumstances and configurations, may affect future costs and provide cost savings. Circumstances will vary. Intel does not guarantee any costs or cost reduction.
Results have been estimated based on internal Intel analysis and are provided for informational purposes only. Any difference in system hardware or software design or configuration may affect actual performance.
