Core i5-3xxx Models (Desktop)

The Core i5-3xxx models are based on the Ivy Bridge microarchitecture and are also known as the third-generation Core i5 processors. They use the socket LGA1155, the same used by the second-generation Core i5 processors. The integrated memory controller supports dual-channel architecture as well as 1,333 MHz and 1,600 MHz DDR3 memories. They have an integrated PCI Express 3.0 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, which is listed as 5 GT/s by Intel). All models (except the “P” models) have an integrated DirectX 11 video controller with six (Intel HD 2500 graphics) or 12 (Intel HD 4000 graphics) processing units, running at 650 MHz with a “boost” clock of 1.25 GHz on 35xx models, 1.1 GHz on 34xx models or 1.05 GHz on 33xx models. Models with integrated video support three displays (previous generations support two).

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.
