Clocks
Clocks	P-cores3.7GHzbase/up4.9GHz turbo;E-cores2.8GHzbase/up3.6GHz turbo. TurboBoost2.0; noTurboBoostMax3.0.	Maximum turbo is a single-core frequency; sustained clocks depend on cooling and motherboard power settings. CPU, graphics and memory overclocking require a supported chipset. Intel publishes TDP without a separate maximum turbo-power figure.
