Clocks
Clocks	Maximum turbo is a single-core frequency; sustained clocks depend on cooling and motherboard settings. Intel's June 2013 availability notice and Puget Systems' June launch lineup establish the sale month; they do not establish a worldwide first-sale day.	Maximum turbo is a single-core frequency. Intel also publishes a 37 W configurable TDP-down mode at a 2.2 GHz base frequency. Intel's June 2015 driver notes describe the model as newly launched; Velocity Micro offered systems immediately in June, while PC Gamer reported delayed availability of separately boxed processors.
