| Processor Speed: | 2.8 GHz | Processor Type: | Core i5 (I5-760) |
| Details: | This model is powered by a 64-bit Intel Core i5 "Lynnfield" processor with quad cores (four independent processor cores on a single silicon chip). Each core has one thread, for a total of four threads for the system, as well as a dedicated 256k level 2 cache. The processor cores share an 8 MB level 3 cache. It also supports "Turbo Boost" -- 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) -- up to 3.33 GHz when needed. However, it does not support Hyper Threading. Also see: How much faster are the "Mid-2010" Aluminum iMac models than the "Late 2009" models? |
