Core i5-2xxx Models (Desktop)
In the table below, we listed all Core i5-2xxx desktop CPU models, which are based on the Sandy Bridge microarchitecture. They are also called second-generation Core i5 processors and use the socket LGA1155. The integrated memory controller supports dual-channel architecture as well as 1,066 MHz and 1,333 MHz DDR3 memories. They also have an integrated PCI Express 2.0 controller supporting one x16 connection, two x8 connections, one x8 connection or two x4 connections. Communication with the motherboard chipset is achieved through a DMI bus (2 GB/s each direction, listed as 5 GT/s by Intel). All models (except the 2550K and the “P” models) have an integrated DirectX 10.1 video controller running at 650 MHz with a 1.25 GHz “boost” clock or 850 MHz with a 1.1 GHz “boost” clock, with six (HD 2000) or 12 (HD 3000) processing cores. Models with integrated video support two displays.
Second-generation Core i5 desktop CPUs with four cores don’t support the Hyper-Threading technology. This means that the operating system will recognize all these CPUs as having four cores. However, while on quad-core models these cores are all “real,” on the dual-core model two of these cores are “real” and the other two are simulated.

TDP stands for Thermal Design Power and indicates the CPU maximum thermal dissipation, i.e., the CPU cooler must be able to dissipate at least this amount of heat.
* The temperatures listed above are Tcase, which is the maximum external temperature of the CPU. On some other models, the manufacturer lists Tjunction, which is the maximum internal temperature of the CPU. The two are not comparable.
