On September 8, 2009, Intel released the first Core i5 processor: The Core i5 750,[2] which is a 2.66 GHz quad-core Lynnfield processor with Hyper-threading disabled. 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. 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.
The Core i5-5xx mobile processors are named Arrandale and based on the 32 nm Westmere shrink of the Nehalem microarchitecture. Arrandale processors have integrated graphics capability but only two processor cores. They were released in January 2010, together with Core i7-6xx and Core i3-3xx processors based on the same chip. The L3 cache in Core i5-5xx processors is reduced to 3 MB, while the Core i5-6xx will use the full cache and the Core i3-3xx will have no support for Turbo Boost.[3] Clarkdale, the desktop version of Arrandale, is sold as Core i5-6xx, along with related Core i3 and Pentium brands. It has Hyper-Threading enabled and the full 4 MB L3 cache.[4]
On January 9, 2011, Intel released new quad-core Core i5 processors based on the "Sandy Bridge" microarchitecture at CES 2011. New dual-core mobile processors and desktop processors arrived in February 2011. The desktop CPUs now all have four unhyperthreaded cores (like the i5-750), with the exception of the i5-2390T. Special ultra-low voltage (2xxxT), low-voltage (2xxxS), and unlocked versions (2xxxK) of "Sandy Bridge" i5 CPUs are also available. DMI bus running at 5 GT/s
