We all know that many components go into the making of a full-fledged computing system. These components ultimately determine the system’s overall functionality. One such crucial component of every system is the motherboard. While the CPU is considered the brains of every computer, the motherboard/processor is recognized as the heart. Every operation directly or indirectly involved with the PC’s functioning is carried out by the motherboard, also known as the mainboard, system board, baseboard, or logic board. The motherboard is located inside of your computer on a system tray.
A motherboard comprises multiple components that are essential for the smooth and efficient functioning of your system. The motherboard is the route through which various computer peripherals interact. One such crucial ingredient of your system’s processor is its CPU socket. The CPU socket consists of pins that provide either mechanical or electrical connections between your system’s microprocessor and the circuit board.
The CPU socket facilities CPU access while preventing damage to your system every time you insert or remove a computer peripheral. These CPU sockets tend to be different for Intel core processors and AMD CPUs. With newer introductions each year, it becomes essential for you to keep up with the evolving technology. The processor is the most crucial component of your PC. Whether you use your PC for gaming, graphics design, video editing, or other “heavy” operations. You need to invest in the right high-performance processor.
While the Intel 1150, 1151, and 1200 CPU sockets have been in the market, Intel’s latest LGA 1700 socket is one making the headlines. These CPU sockets have done exceptionally well when it comes to improving the motherboard’s overall functionality. Nearly every new CPU comes with its socket. And with the release of the Intel LGA 1700 CPU socket, Intel has kept up with the tradition. However, with a new socket in the offing, you currently have 4 sockets to choose from.
Choosing can be tough if there are a number of options at your disposal. To make this process simpler, you need to know about everything all these sockets have to offer. In this article, we will walk you through the differences between the LGA 1150 vs 1151 vs 1200 vs 1700.
Note: Having already used pins and cartridges for the CPUs, Intel has moved on to a pin mounting system called the Land Grid Array (LGA). This means that these CPUs use electrical contact pads on the rear with the pins already inside the CPU socket on the motherboard.
LGA 1150 Review
One of the most popular types of processors currently available for purchase is Intel’s LGA 1150. The LGA 1150, generally referred to as the H3 socket, was launched post the release of Intel’s LGA 1155 H2 socket. Built on the Haswell architecture, these CPU sockets comprises 1150 pins that enable communication between the motherboard and the processor, hence the name. The LGA 1150 is fully compatible with all Intel processors and also supports both Haswell and Broadwell processors.
A motherboard equipped with the LGA 1150 CPU socket can fully support HDMI, VGA, and DVI connections and is compatible with the DDR3 RAM. The CPU cooling is backward compatible, meaning it offers full compatibility with the older 1156 and 1155 LGA CPU sockets. Unfortunately, these LGA 1150 CPU sockets are now outdated since they do not support DDR4 RAM. The LGA1150 is compatible with Intel B85, H81, H87, Q85, Q87, Z87, H97, Z97 desktop chipsets and the C226 server chipsets. However, it is NOT compatible with the Skylake processor.
LGA 1151 Review
Also built on Haswell’s microarchitecture, the LGA 1151 CPU socket was launched as the successor to the 1150 CPU socket in 2015. Referred to as the H4 socket, the LGA 1151 is the second revision for Coffee Lake CPUs. The LGA 1151 has 1151 pins on the bottom of the socket that facilitate communication between the processor and the motherboard. 1151 is currently the desktop socket and is based on the 7th gen, 8th gen and 9th generations of Intel Chipsets. This CPU socket uses the right orientation with the heatsink fastening holes placed in a square formation. The LGA 1151 supports the following chipsets.
The LGA 1151 CPU sockets allow for the same cooling as the older 1150 and 1151 H2 sockets and can carry HDMI, DVI, DisplayPort, and VGI connections. The 1151 currently has two versions available which aren’t compatible with each other. The first generation of these motherboards has limited overclocking support but Kaby Lake models did not – Z270 is an exception. The second generation does not allow overclocking except for Z370 and Z390 chipsets.
LGA 1200 Review
The LGA 1200 is a modified version of the 1151 H4 socket and is compatible with the Comet Lake and Rocket Lake Desktop CPUs. The LGA 1200 was introduced as a potential replacement to the 1151 CPU Socket. 1200 comprises 1200 pins mounted at the rear of the motherboard that facilitates communication between the motherboard and the processor.
It comes with additional 49 pins than 1151 that allow for improved power efficiency and eventual updates with multiple I/O devices. However, this LGA 1200 isn’t compatible with the older generation CPU’s meaning that you won’t use the Comet Lake and Rocket Lake Desktop CPUs on the older LGA Sockets. Like the LGA 1151, it has four heatsink holes allowing for the same cooling as the older 1150 and 1151 Intel LGA sockets.
LGA 1700 Review
Intel’s LGA 1700 CPU Socket is Intel’s latest release along with the newly launched 12th generation Alder Lake CPUs. With this new socket, Intel has made room for additional pins making this socket accommodate 1700 pins. In simple words, the Intel LGA 1700 is a perfect replacement for the previous LGA 1200 CPU socket. The Intel 1700 socket features a taller and asymmetrical design.
However, this redesign means that you can only use this socket with 12-generation Intel Core processors. Compared to the earlier CPU sockets, the 1700 is 7.5 mm longer with an unchanged width of 37.5 mm. It has over 1700 protruding pins that make contact with the pads on the processor. Given its larger size, Intel has also made significant changes in the heatsink design. To go with the hole pattern, Intel has changed the heatsink’s seating plane height along with the maximum thermal solution centre to provide maximum cooling when in use.
