*Requires a system with Intel® Turbo Boost Technology. Intel® Turbo Boost Technology and Intel® Turbo Boost Technology 2.0 are only available on select Intel® processors. Consult your PC manufacturer. Performance varies depending on hardware, software, and system configuration. For more information, visit http://www.intel.com/go/turbo
2 Based on STREAM_OMP Triad results. 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. Consult other information and performance tests to help fully evaluate your contemplated purchases, including the performance of that product when combined with other products.
1 Source: Performance comparison using SPECfp*_rate_base2006 benchmark. Baseline score of 267 on prior generation 2S Intel® Xeon® processor X5690 (3.46 GHz, 6 core, 12MB L3, 6.4 GT/s, 130W) based platform is based on best published score to www.spec.org as of 6 September 2011. For more details, see: http://www.spec.org/cpu2006/results/res2011q1/cpu2006-20110131-14172.html. New score of 486 on 2S Intel® Xeon® processor E5-2690 (2.90 GHz, 8 core, 20MB L3, 8.0 GT/s, 135W) based platform is based on Intel® internal measured estimates as of 6 September 2011 using an Intel® Rose City platform with two Intel® Xeon® processor E5-2690, Turbo Enabled, EIST Enabled, Hyper-Threading Enabled, 64 GB memory (8 x 8GB DDR3-1600), Red Hat* Enterprise Linux Server 6.1 beta for x86_6, Intel® Compiler 12.1.
2 Source: The claim of up to 30% reduction in I/O latency is based on Intel® internal measurements of the average time for an I/O device read to local system memory under idle conditions for the Intel® Xeon® processor E5-2600 product family versus the Intel® Xeon® processor 5600 series.
3 Source: The Intel® Xeon® processor E5 product family supports Intel® Advanced Vector Extensions (Intel® AVX), which increases maximum vector size from 128 to 256 bits, so up to twice the work can be accomplished per clock cycle during floating point and vector operations versus the Intel® Xeon® processor 5600 series.
4 Intel® Turbo Boost Technology requires a platform with a processor with Intel® Turbo Boost Technology capability. Intel® Turbo Boost Technology performance varies depending on hardware, software and overall system configuration. Check with your platform manufacturer on whether your system delivers Intel® Turbo Boost Technology. For more information, see http://www.intel.com/technology/turboboost. http://www.intel.com/technology/turboboost.
5 Source: The claim of up to 2.3x I/O performance is based on Intel® internal measurements comparing 1-socket SNB data for an L2 forwarding test using 8x10 GbE ports for the Intel® Xeon® processor E5 product family versus the Intel® Xeon® processor 5600 series.
