Hi!
- Feature is enabled by default for single socket systems With Intel® Turbo Boost Max Technology 3.0 (ITMT), single-threaded performance is optimized by identifying processor's fastest core and running critical workloads on it. Refere to: http://www.intel.com/content/www/us/en/architecture-and-technology/turbo-boost/turbo-boost-max-technology.html
That does not really explain much. How does it work? Do the different cores have different max frequencies due to manufacturing differences? Ot is it running the workload on coldest core?
