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. For more complete information visit the benchmarking pages at Intel's website. Intel technologies' features and benefits depend on system configuration and may require enabled hardware, software or service activation. Performance varies depending on system configuration. No computer system can be absolutely secure. Check with your system manufacturer or retailer to learn more.
1 - Maximum processor frequency with Intel® Turbo Boost 2.0.
2 - Altering clock frequency or voltage may damage or reduce the useful life of the processor and other system components, and may reduce system stability and performance. Product warranties may not apply if the processor is operated beyond its specifications. Check with the manufacturers of system and components for additional details.
3 - Intel® Core™ i9-9900KS is a special edition of Intel® Core™ i9-9900K processor, with even better performance. Performance results are based on testing as of July 11, 2019 and may not reflect all publicly available security updates. See configuration disclosure for details. As measured by in-game benchmark mode performance (score or frames per second) where available, or frames per second where benchmark mode is unavailable.
