The second-generation Core i5 targeted to laptops, which use the Sandy Bridge microarchitecture, can use two different pinouts, BGA1023 or socket G2, and have an integrated dual-channel DDR3 memory controller supporting 1,066 MHz, 1,333 MHz, and 1,600 MHz DDR3 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). These processors also have an integrated DirectX 10.1 video controller running at 350 MHz with a 1.2 GHz “boost” clock on models with a TDP of 17 W, or 650 MHz with a 1.3 GHz “boost” clock on models with a TDP of 35 W, all with 12 processing cores (HD 3000 graphics engine). 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.
The Core i5-3xxx models are based on the Ivy Bridge microarchitecture and are also known as the third-generation Core i5 processors. They use the socket LGA1155, the same used by the second-generation Core i5 processors. The integrated memory controller supports dual-channel architecture as well as 1,333 MHz and 1,600 MHz DDR3 memories. They have an integrated PCI Express 3.0 controller supporting 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). All models (except the “P” models) have an integrated DirectX 11 video controller with six (Intel HD 2500 graphics) or 12 (Intel HD 4000 graphics) processing units, running at 650 MHz with a “boost” clock of 1.25 GHz on 35xx models, 1.1 GHz on 34xx models or 1.05 GHz on 33xx models. Models with integrated video support three displays (previous generations support two).

As their desktop counterparts, the Core i5-3xxx models targeted to mobile computers are based on the Ivy Bridge microarchitecture and are also known as the third-generation Core i5 processors. They can use either the BGA1023 pinout or the socket S2 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 3.0 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). All models have an integrated DirectX 11 video controller with 12 execution units (Intel HD 4000 graphics). This is one of the main differences between the mobile and the desktop models, since desktop models use the Intel HD 2500 graphics (six execution units). On “M” models, the graphics engine works at 650 MHz with 1.2 GHz at “boost” mode, while on “U” models, the graphics engine works at 350 MHz with a “boost” mode of 1.15 GHz on 34xx models or 1.05 GHz on 33xx models. All models support three displays (previous generations support two). Differently from the desktop models, mobile third-generation Core i5 processors are dual-core CPUs with Hyper-Threading (HT) technology, which simulates two logical processing cores in each physical core.

Core i5-4xxx models are based on the Haswell microarchitecture and are also known as the fourth-generation Core i5 processors. They use a new socket, LGA1150, which is not compatible with motherboards developed for previous models. The integrated memory controller supports dual-channel architecture as well as 1,333 MHz and 1,600 MHz DDR3 memories. They have an integrated PCI Express 3.0 controller supporting 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). These processors support AVX2 instructions, not available on previous models. All models have an integrated DirectX 11.1 video controller, and two engines are available at the moment: HD 4600 (codenamed “GT2”, 20 processing units) and Iris Pro 5200 (codenamed “GT3e”, 40 processing units, and video memory integrated into the CPU).

The fourth-generation Core i3 processors targeted to mobile computers are based on the Haswell microarchitecture. These processors support AVX2 instructions, not available on previous models. The “U” and “Y” models carry an integrated south bridge chip with a four-port USB 3.0 controller and a four-port SATA-600 controller. On these models, the PCI Express controller supports only one x4 connection or four x1 connections. On the other models, the PCI Express 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). Several graphics engines are available, all DirectX 11.1: HD 4200 (codenamed “GT1”, 10 processing units), HD 4400 (codenamed “GT2”, 20 processing units), HD 4600 (codenamed “GT2”, 20 processing units), HD 5000 (codenamed “GT3”, 40 processing units), and Iris 5100 (codenamed “GT3”, 40 processing units). 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. Differently from the desktop models, mobile third-generation Core i5 processors are dual-core CPUs with Hyper-Threading (HT) technology, which simulates two logical processing cores in each physical core.

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.
Let’s compare the performance of two competing CPUs that are being released this week, the Intel Core i5-2500K (3.3 GHz) and the AMD Phenom II X4 975 BE (3.6 GHz).
Core 2 Extreme QX9650 is the most high-end desktop CPU available today, being a quad-core CPU manufactured in 45 nm process, running at 3 GHz internally and 1,333 MHz externally, featuring 12 MB L2 memory cache and the new SSE4 instruction set. Is it really faster than “older” quad-core CPUs? Check it out.
