Core i5

January 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 Core i5-2xxx line of desktop processors are mostly quad-core chips, with the exception of the dual-core Core i5-2390T, and include integrated graphics, combining the key features of the earlier Core i5-6xx and Core i5-7xx lines. The suffix after the four-digit model number designates unlocked multiplier (K), low-power (S) and ultra-low-power (T). The desktop CPUs now all have four non-SMT cores (like the i5-750), with the exception of the i5-2390T. The DMI bus is running at 5 GT/s.

The mobile Core i5-2xxxM processors are all dual-core chips like the previous Core i5-5xxM series and share most the features with that product line.
