Notes:

The following hardware was used for measurements:
- Intel® Xeon® Processor X5570: 2 four-core CPUs (8Mb Intel® Smart Cache), 2.93GHz, 48 GB of RAM
- Intel® Xeon® Processor E7-4870: 4 ten-core CPUs (30Mb Smart Cache), 2.4GHz, 64GB of RAM
- Intel® Xeon® Processor E5-2690: 2 eight-core CPUs (20Mb Intel® Smart Cache), 2.9GHz, 32GB of RAM
Performance is measured over the vector length of 1000 elements.

Optimization Notice
Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. 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. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice. Notice revision #20110804
