All Core i3 Models

Core i3-5xx Models (Desktop)

In the table below, we listed all Core i3-5xx CPU models. These are desktop models based on the Nehalem microarchitecture, and are also called first-generation Core i3 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, which is listed as 2.5 GT/s by Intel). All models have an integrated DirectX 10 video controller with six execution units running at 733 MHz, using an engine that is known as “Intel HD Graphics.” These processors support two video monitors.

All Core i3 CPUs support 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.

SLBLR 530 2.93 GHz 2 Yes HD Graphics 733 MHz 4 MiB 32 nm 73 72.6 0.65 – 1.4

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.
