1.2 GHzCore m3 (M3-7Y32)
Details:This model is powered by a 14 nm, 1.2 GHz 64-bit "Seventh Generation/Kaby Lake" Intel Mobile m3 (M3-7Y32) processor which includes two independent processor "cores" on a single silicon chip. Each core has a dedicated 256k level 2 cache, shares 4 MB of level 3 cache, and has an integrated memory controller (dual channel).

This system also supports "Turbo Boost 2.0" -- which "automatically increases the speed of the active cores" to improve performance when needed (up to 3.0 GHz for this model) -- and "Hyper Threading" -- which allows the system to recognize four total "cores" or "threads" (two real and two virtual).
