Core i3-4xxx Models (Desktop)

Core i3-4xxx models are based on the Haswell microarchitecture and are also known as the fourth-generation Core i3 processors. They use a new socket, LGA1150, which is not compatible with motherboards developed for previous models.

These processors have a PCI Express 3.0 controller, instead of a 2.0 as other models. This controller supports 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).

Another difference is the support for AES-NI and AVX2 instructions, not available on previous models.

Two graphics engines are available at the moment, both DirectX 11.1 with 20 execution engines (codenamed “GT2”).

As mentioned earlier, 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.

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.
