Intel Turbo Boost Max Technology 3.0 identifies the best performing core(s) on a processor and provides
increased performance on those cores by taking advantage of power and thermal headroom. Intel® Turbo
Boost Max Technology 3.0 frequency is the clock frequency of the CPU when running in this mode.
NOTE: Processors that do not have certain turbo functionality are denoted as N/A.
Multicore is designed to improve performance of certain software products. Not all customers or
software applications will necessarily benefit from use of this technology. Performance and clock
frequency will vary depending on application workload and your hardware and software
configurations. Intel’s numbering, branding and/or naming is not a measurement of higher
performance.
