SPEC CPU* 2006 is a benchmark to measure system efficiency during integer and floating point operations. It consists of an integer test suite containing 12 applications and a floating-point test suite containing 17 applications that are extremely computing-intensive and concentrate on the CPU and memory. Other components, such as disk I/O and network, are not measured by this benchmark. SPEC CPU2006 contains two different methods of performance measurement: The first, "speed," determines the time required to complete a single task; the second, "rate," determines the throughput—that is, how many tasks can be completed in parallel. Both methods are additionally subdivided into two measuring runs: "base" and "peak," which differ in the way the compiler optimization is used. The "base" values are always used when results are published, and the "peak" values are optional. For more information please visit: http://www.spec.org/cpu2006.
STREAM has become a defacto standard for measuring a platforms memory bandwidth. STREAM performs a series of reads and writes to/from very large arrays to determine memory bandwidth. There are four different outputs of STREAM (Add, Copy, Scale & Triad). Most use the Triad result. For more information, visit http://www.cs.virginia.edu/stream/.
Benchmark results were obtained prior to implementation of recent software patches and firmware updates intended to address exploits referred to as "Spectre" and "Meltdown". Implementation of these updates may make these results inapplicable to your device or system.
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.

Intel does not control or audit the design or implementation of third party benchmarks or websites referenced in this document. Intel encourages all of its customers to visit the referenced websites or others where similar performance benchmarks are reported and confirm whether the referenced benchmarks are accurate and reflect performance of systems available for purchase.
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 and SSE3 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.
