What Should I Look for When Buying an LGA 1155 CPU?

To decide which LGA 1155 CPU is best for you, you should consider the following:

Socket Connectivity:

Your CPU is connected to your motherboard by a socket. To make sure that the motherboard and CPU are compatible, you must check the compatibility. They are not only physically connected but also electrically. It should be easy for the CPU to connect to the motherboard socket as the compatibility should be based on that.


The short form of gigahertz is GHz. Your CPU’s speed is determined by its frequency. GHz is measured in cycles per second. You should find a processor with more cycles per second so your gaming experience is more efficient.


The cache is a term used to describe the memory of your processor. For temporary storage, the cache serves as faster memory. Caches are usually small, so if you get a bigger cache, you’ll be able to recover large amounts of information faster. In the gaming world, data recovery is essential.

Thermal Scheme Power:

You can interpret the amount of heat generated by your CPU using the Thermal Scheme Power feature. So, if you want your processor to perform well, protect it from overheating. You can buy CPU coolers for your CPU too.

FAQ (Frequently Asked Questions)

What is the Difference Between Socket 1150 and 1155?

The LGA 1150 is a successor of the 1155 socket. The 1150 socket supports the new fourth and fifth-generation Intel processors, while the 1155 socket was built for the second and third-generation Intel chips. The 1150 socket is based on the Haswell microarchitecture, and the 1155 socket is based on the Ivy Bridge microarchitecture.  

LGA 1155 supports DDR4?

The LGA 1155 motherboards cannot support DDR4 memory because when they were produced, DDR3 was the newest version available, and that’s what they support. 

Will an LGA 1155 Fit an 1151? 

That won’t work because each socket has a different number of pins and a different function. So, You may end up damaging the CPU if you use a different socket with a different processor.

Final Words

It will be more enjoyable to use your computer system if you install the best LGA 1155 CPU. Also the CPU-hungry applications and games will run without any lag. Additionally, you will be more productive and spend less time on tasks with such an upgrade. The best CPU for your PC should be the top priority for avid gamers, video editors, graphic editors, video animators, or office workers.
