|Processor Speed:||2.7 GHz||Processor Type:||Core i5 (I5-2500S)|
|Details:||This model is powered by a 32 nm, 64-bit Intel Core i5 “Sandy Bridge” processor with quad cores (four independent processor cores on a single silicon chip, each with one thread). Each core has a dedicated 256k level 2 cache and all processor cores share a single 6 MB level 3 cache. It also supports Turbo Boost 2.0 (up to 3.7 GHz) — which “automatically boosts the processor speed based on workload” (so if an application is only using one of the four cores it will automatically increase the speed of the core in use and turn off the unused cores).
