Core i5-4xx and 5xx Models (Mobile)

The first-generation Core i5 targeted to laptops, named 4xx and 5xx, uses the Nehalem microarchitecture. They can use two different pinouts, BGA1288 or socket G1, and have an integrated dual-channel DDR3 memory controller supporting 800 MHz and 1,066 MHz DDR3 memories. (“UM” models support only DDR3-800 memories.) They have an integrated PCI Express 2.0 controller supporting one x16 connection and an integrated DirectX 10 video controller running at 500 MHz with a 766 MHz “boost” clock (166 MHz with a 500 MHz “boost” clock in “UM” models). Communication with the motherboard chipset is achieved through a DMI bus (1 GB/s per direction, which is listed as 2.5 GT/s by Intel). The models listed below support two video monitors.

All Core i5 mobile CPUs are dual-core processors supporting Hyper-Threading (HT) technology, which simulates two logical processing cores in each physical core. Therefore, they are recognized by the operating system as four-core CPUs.

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 Tjunction, which is the maximum internal temperature of the CPU. On some other models, the manufacturer lists Tcase, which is the maximum external temperature of the CPU. The two are not comparable.
