Core i5-4xxx Models (Desktop)

Core i5-4xxx models are based on the Haswell microarchitecture and are also known as the fourth-generation Core i5 processors. They use a new socket, LGA1150, which is not compatible with motherboards developed for previous models.

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).

These processors support AVX2 instructions, not available on previous models.

All models have an integrated DirectX 11.1 video controller, and two engines are available at the moment: HD 4600 (codenamed “GT2”, 20 processing units) and Iris Pro 5200 (codenamed “GT3e”, 40 processing units, and video memory integrated into the CPU).

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.
