Core i5 3.2Ghz (2500k,Fsb1155,C6MB), processor

The first Core i5 using the Nehalem microarchitecture was introduced on September 8, 2009 as a mainstream variant of the earlier Core i7, the Lynnfield core. Lynnfield Core i5 processors have an 8 MB L3 cache, a DMI bus running at 2.5 GT/s and support for dual-channel DDR3-800/1066/1333 memory and have Hyper-threading disabled. The same processors with different sets of features (Hyper-Threading and other clock frequencies) enabled are sold as Core i7-8xx and Xeon 3400-series processors, which should not be confused with high-end Core i7-9xx and Xeon 3500-series processors based on Bloomfield.
