Intel® Xeon® processor 5000 sequence - High Performance Computing

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. Source: Published and Intel internal data as of February 14, 2011. Please see configuration details links above for system configuration details. For more information go to www.intel.com/performance.

2. Relative performance for each benchmark is calculated by taking the actual benchmark result for the first platform tested and assigning it a value of 1.0 as a baseline. Relative performance for the remaining platforms tested was calculated by dividing the actual benchmark result for the baseline platform into each of the specific benchmark results of each of the other platforms and assigning them a relative performance number that correlates with the performance improvements reported.

4. SPECompM* and SPECompL* results on Intel® Xeon® processor 5600 series-based server were obtained using 24 OpenMP threads over two sockets, on Intel® Xeon® processor 5500 series-based server 16 OpenMP threads over two sockets were used, on Intel® Xeon® processor 5400 series-based server 8 OpenMP threads over two sockets were used. For more information see the detailed HPC section.

5. SPECmpi*M2007 results on Intel® Xeon® processor 5500 and Intel® Xeon® processor 5400 series-based clusters were obtained for power of two MPI rank counts from 16 to 128 in fully-subscribed mode on each cluster node. Results on Intel® Xeon® processor 5600 were obtained on the same node counts in fully-subsribed mode with MPI rank counts from 24 to 192. For more information see the detailed HPC section.

6. Intel® Virtualization Technology requires a computer system with an enabled Intel® processor, BIOS, virtual machine monitor (VMM) and, for some uses, certain platform software enabled for it. Functionality, performance or other benefits will vary depending on hardware and software configurations and may require a BIOS update. Software applications may not be compatible with all operating systems. Please check with your application vendor.

7. Intel® Hyper-Threading Technology (Intel® HT Technology) requires a computer system with a processor supporting Intel® HT Technology and an Intel® HT Technology-enabled chipset, BIOS, and operating system. Performance will vary depending on the specific hardware and software you use. For more information including details on which processors support Intel® HT Technology, see www.intel.com/products/ht/hyperthreading_more.htm.

8. 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 www.intel.com/content/www/us/en/architecture-and-technology/turbo-boost/turbo-boost-technology.html.

9. 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.

10. Intel® products are not intended for use in medical, life saving, life sustaining, critical control or safety systems, or in nuclear facility applications. All dates and products specified are for planning purposes only and are subject to change without notice.

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