◊1 Requires a system with Intel® Turbo Boost Technology capability. Intel Turbo Boost Technology 2.0 is the next generation of Intel Turbo Boost Technology and is only available on select Intel® processors. Consult your PC manufacturer. Performance varies depending on hardware, software, and system configuration. For more information, visit www.intel.com/go/turbo.
◊2 Built-in visual features are not enabled on all PCs and optimized software may be required. Check with your system manufacturer. Learn more at www.intel.com/go/biv.
◊3 Available on select Intel® Core™ processors. Intel® Hyper-Threading Technology (Intel® HT Technology) requires an Intel® HT Technology-enabled system. Consult your PC manufacturer. Performance will vary depending on the specific hardware and software used. For more information, including details on which processors support Intel® HT Technology, visit www.intel.com/info/hyperthreading/.
‡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.
‡2 Based on SPECint_rate_base2006* and SPECfp*_rate_base2006 scores. Configuration: Intel® Core™ i7-980X processor Extreme Edition, compared with Intel® Core™ i7-975 processor Extreme Edition. Results based on internal Intel analysis and are provided for informational purposes only. See www.intel.com/performance/desktop/index.htm for additional information.
‡3 PCMark* Vantage, a hardware performance benchmark for PCs running Windows 7* or Windows Vista*, includes a collection of various single and multithreaded CPU, graphics, and HDD test sets with a focus on Windows* application tests. Configurations: Pre-production 2nd generation Intel® Core™ i5-2400 processor (desktop) and 2nd generation Intel® Core™ i5-2410M processor (laptop), compared with Intel® Core™2 Duo processor E6550 (desktop) and Intel® Core™2 Duo processor T7250 (laptop), typical three- to four-year-old installed base products as defined by IDC (Dec'08).

‡4 Warning: Altering clock frequency and/or voltage may: (i) reduce system stability and useful life of the system, processor and other system components; (ii) cause the processor and other system components to fail; (iii) cause reductions in system performance; (iv) cause additional heat or other damage; and (v) affect system data integrity. Intel has not tested, and does not warranty, the operation of the processor beyond its specifications. Intel has not tested, and does not warranty, the operation of other system components beyond their industry standard specifications. Intel assumes no responsibility that the processor and other system components, including if used with altered clock frequencies and/or voltages, will be fit for any particular purpose.
