1.7 GHz Core i7 (I7-4650U) 
Details:This model is powered by a 22 nm, 64-bit "Fourth Generation" Intel Mobile Core i7 "Haswell ULT" (I7-4650U) 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 3.3 GHz for this model) -- and "Hyper Threading" -- which allows the system to recognize four total "cores" or "threads" (two real and two virtual).
