This model is powered by a 32 nm, 64-bit Intel Mobile Core i5 "Sandy Bridge" (I5-2415M) processor which includes two independent processor "cores" on a single silicon chip. Each core has a dedicated 256k level 2 cache, shares 3 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 -- and "Hyper Threading" -- which allows the system to recognize four total "cores" or "threads" (two real and two virtual).
