LGA 1151 vs 1150

When it comes to building a Pc on our own, most of us want maximum performance from our system and to achieve this every component matters. Most people consider GPU in the first place of prioritization and buy one with the highest-quality that covers the majority of the budget.

The process of building a future-proofing PC isn’t everyone’s cup of tea. There are a lot of things that need to be kept in mind. You cannot just buy high dollar components and put them together. This isn’t the way how it works. Not every part is compatible with one another, so you should focus more on research rather than buying everything heavy on your wallet.

Most people are aware of GPUs, Keyboards, mice, and other simple components. But it can be confusing when buying a motherboard socket and chipsets. What are these sockets and chipsets? Which one you should choose for your PC? If you don’t have any idea about these, you should consider reading further.

In this article, we bring you two products that are famous in the community which are LGA 1151 and 1150. You will learn about compatibility, its pros and cons, and other related information.


Why Do Sockets Matter when building a Computer?

The motherboard is the heart of a computer. It is crucial to buy a motherboard that determines the compatibility of future upgrades. Technology is progressing every day and it brings an evolution in components that inevitably change the types of connections. This sometimes leaves our computers obsolete and un-upgradable.

Apart from the number of cores and clock speed, the type of socket in a CPU plays an important role. The socket allows users to know the type of generation of the CPU and also determines the other components that are compatible with it.

Currently, the land grid array (LGA) is the standard for CPU. Historically, sockets used holes that the chip plugs into. For tiny pins in the CPU chip, LGA sockets have many tiny receptors. Those pins provide individual connections between the chip and the motherboard. There are many different types of sockets available including T, H, H1, H2, H3, and H4.

LGA 1151; Compatibility, Pros, and Cons

LGA 1151 is also known as the H4 socket. This socket was developed back in 2015 as an upgrade of LGA 1150. There are two generations of this socket. The first generation supported Intel’s Skylake and Kaby Lake CPUs and the second generation supports H110, H170, B150, Q150, Q170, and Z170.

The points for heatsink attachment are similar to 4 points in a square with a lateral length of 75 mm. due to this, this allows using the same fans used in older LGA 1150 and 1155 chips. For better video quality it carries DVI, HDMI, and DisplayPort connections. This socket is compatible with DDR3, DDR4, and DDR3L ram which is quite better than older versions that supported only DDR3 ram only.


  • Support DDR3, DDR4, and DDR3L memory
  • Support Skylake, Kaby Lake, and Coffee Lake processors
  • Compatible with 100, 200, and 300 chipset series


  • Offers 1151 pins to create contact

LGA 1155; Compatibility, Pros, and Cons

LGA 1155 also known as socket H2 is an LGA socket that has superseded socket 1156. This socket was introduced back in 2011 at the same time when second-generation core CPUs were launched.

LGA 1155 is compatible and works with the latest generations of Intel, Pentium, Xeon, and Core i3, i5 and server processers that acquire 4 CPU cores, that has 8 MB of L3 cache, and work at a frequency range of between 1.2 GHz to 3.7 GHz.

Socket 1155 supports only DDR3 memory with data rates up to 166 MHz, this socket was replaced with the older version (socket 1150) in 2013.

The dimensions of these sockets are (ILM) is 1.67″ x 1.67″ (4.25 cm x 4.25 cm) without an independent loading mechanism. Socket H2 has 1155 pins that are arranged to make 40 x 40 contacts with 24 x 16 de-populated in the center. From a top view, the contacts in pins create L-shaped sections that are opposing each other.

Let’s have a look at some pros and cons of socket H2.


  • Haswell, Haswell-WS, and Broadwell processors
  • It comes with 1155 pins to make contacts
  • Compatible with 8 and 9 series of Intel chipsets


  • It doesn’t support DDR4 and DDR3L
  • It is only compatible in 8 and 9 series of Intel chipset

What makes LGA 1151 more popular?

Both LGA 1151 and 1155 have their own pros and cons and users have different uses and expectations from each. As we compared these two sockets, we conclude that 1151 is better than in 1155. Not just because it is the freshest socket in the market but also it has a lot of undeniable features that help to improve CPU performance and also aid in getting your work done with ease.

Here in this section, you will understand why socket 1151 is most popular among the user’s community.

               Specification of LGA 1151 Socket
Video Outputs Compatibility DVI, HDMI 1.4, and Display Port 1.2.
Chipsets Compatibility DIMM slots 2/4 and SATA 3.0ports 4/6.
Heatsink Attachment 4 square points with 75mm lateral length.


The prominent and simple difference between these two products is the pins number. Pins make sure that your CPU gets better performance. LGA 1151 has 1151 pins that help your CPU perform better with great access to do more work.

LGA 1151 is not only known for providing a great connection to the CPU but also enables users to transfer data at a good speed. A good socket system means you will get a faster speed of bandwidth whenever you are doing work on your system.

Also, LGA 1151 socket supports DDR4, DDR3, and DDR3L memory storage. This allows users to get a better option to store data without any hurdle. Compatible Ram in LGA 1151 also makes fine shifting of data.

LGA 1151 comes with 6 different chipset compatibility that makes sure fine fitting with B150, H110, H170, Q150, Q170, and Z170 chipset support.

The feature that makes LGA 1151 better than 1155 is the variety of video outputs it supports. Not only it works fine with DVI and HDMI 1.4 outputs but also works efficiently with Display port 1.2 video interface outputs that fit easily.

Also, this socket comes with different size ranges that are mainly designed to fit with 14-nanometer processors easily to increase the work speed.

Moreover, LGA 1151 comes with a fine layout that benefits most users as they can install CPU cooler fans that makes sure no heating of PC parts. It as well ensures the PC is getting fine ease and protected from heat to avoid any flame struggle or burn problems.

Final Thoughts

If you want to build a PC, you should consider sockets in your list. Sockets play an essential role in a Computer. It tells us about the generation of the system and also helps users to know about other compatible components.

In this article, you learned about two different sockets which are LGA 1151 and 1155. Both of these have different compatibility, pros, and cons. You can pick whatever you want but before buying one you should consider doing some research and then go and buy one.

Choose the socket that matches your needs. Good luck.
