All Core i5 Models

Core i5-6xx and 7xx Models (Desktop)

In the table below, we listed all Core i5 6xx and Core i5 7xx CPU models. These are desktop models based on the Nehalem microarchitecture and are also called first-generation Core i5 processors. These models use the socket LGA1156. 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 datapath or two x8 datapaths. Communication with the motherboard chipset is achieved through a DMI bus (1 GB/s per direction, listed as 2.5 GT/s by Intel). All 6xx models have an integrated DirectX 10 video controller with 12 execution units running at 733 MHz or 900 MHz, using an engine that is known as “Intel HD Graphics,” a feature not present on the 7xx models. Models with integrated video support two video monitors.

The 7xx models are quad-core CPUs without the Hyper-Threading technology, while the 6xx models are dual-core CPUs using the Hyper-Threading technology. This means that the operating system will recognize all these CPUs as having four cores. However, while on the 7xx models these cores are all “real,” on the 6xx models 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.
