All Core i3 Models
By Richard Vertrees e Rafael Otto Coelho e Gabriel Torres on October 3, 2013


Introduction

The Core i3 is a CPU series manufactured by Intel aimed at entry-level computers. In this tutorial, we will present a series of quick reference tables for you to compare the main differences between all models released to date.

By the way, the correct name of this line of processors is “Core i3,” not “Intel i3.”

Currently, there are three different generations of Core i3 processors available. In the table below, we describe the main differences between these generations.

Let’s now take a detailed look at all Core i3 models launched so far.

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.

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.

Core i3-3xx Models (Mobile)

The first-generation Core i3 targeted to laptops, named 3xx, 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 667 MHz “boost” clock (166 MHz with 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). These processors support two video monitors.

Core i3-3xxx Models (Mobile)

As their desktop counterparts, the Core i3-3xxx models targeted to mobile computers are based on the Ivy Bridge microarchitecture and are also known as the third-generation Core i3 processors. They can use either the BGA1023 pinout or the socket G2 pinout. The integrated memory controller supports dual-channel architecture as well as 1,333 MHz and 1,600 MHz DDR3, DDR3L, and DDR3L-RS memories. They also have an integrated PCI Express 2.0 controller supporting one x16 connection, two x8 connections, one x8 connection or two x4 connections. Communication with the motherboard chipset is accomplished through a DMI bus (2 GB/s each direction, which is listed as 5 GT/s by Intel).

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.

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.

Core i3-4xxx Models (Mobile)

As their desktop counterparts, the Core i3-4xxx models targeted to mobile computers are based on the Haswell microarchitecture and are also known as the fourth-generation Core i3 processors. They can use either the FCBGA1168 or the FCPGA946 pinout, which are not compatible with the pinout standard used by previous models.

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

An important difference between the desktop and mobile models of the fourth-generation Core i3 is the PCI Express controller, which is 3.0 on desktop models, but 2.0 on mobile versions.

The “U” and “Y” models carry an integrated south bridge chip with a four-port USB 3.0 controller and a four-port (two-port on the 4005U model) SATA-600 controller. On these models, the PCI Express controller supports only one x4 connection or four x1 connections. On “M” models the PCI Express supports one x16 connection, two x8 connections, one x8 connection or two x4 connections.

Four graphics engines are available, all DirectX 11.1: HD 4200 (codenamed “GT1”, 10 execution engines), HD 4400 (codenamed “GT2”, 20 execution engines), HD 4600 (also codenamed “GT2”, 20 execution engines) and Iris 5100 (codenamed “GT3”, 40 execution engines).

The integrated memory controller supports dual-channel architecture as well as 1,333 MHz and 1,600 MHz DDR3L and LPDDR3 (on models “U” and “Y”) memories.

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.
