Things to Consider Before Buying LGA 1151 CPU

It can be quite confusing to figure out which one is the best CPU for LGA 1151 if you don’t know the important factors.

Some criteria need to be fulfilled to achieve the perfect CPU for building your high-end PC. Otherwise, all your hard efforts will go in vain, let alone your hard-earned money.

Clock Speed

One of the most important factors before buying a CPU is to check its clock speed. The speed determines how fast the chip is going to operate. The higher the clock speed, the faster it’s going to be.

It’s measured in GHz or gigahertz. One GHz means one billion cycles per second. Modern CPUs come with a minimum or base clock speed and maximum or turbo speed.

TDP or Thermal Design Profile

This is another important consideration that you should keep in mind. TDP is the quantity of heat that a chip is going to produce at stock speeds. Its generally measured in watts.

Some CPUs have built-in cooling systems, while some don’t have them.

So, you must ensure that you have installed a cooler that is capable of handling the heat dissipation.

On an important note, you should keep in mind that when you overclock the CPU, it’s going to produce more heat. That’s why you must know the TDP so that you can get a suitable cooling system.

Cores

Fundamentally, a core represents a processor. Each processor is able to process a single task, and most of the processors nowadays contain 4 to 8 cores. Therefore, if your CPU has more cores, then you’ll be able to perform more tasks each time, which translates to faster computer operation.

However, it doesn’t mean that you’re going to get the benefits of more cores from every application. As an example, video editing and animation are likely to derive more benefits from many cores. At the same time, video games aren’t going to take much of the benefits.

Threads

Read it carefully, as it might be tricky to grasp at first. A single core can make two threads that are known as multithreading. And most of the processors have this capability.

Now each of the threads has the capacity of executing a certain number of independent tasks. AMD calls it Simultaneous Multithreading (SMT), and Intel calls it Hyper-Threading.

In simple words, if your CPU has more threads, then you’ll be able to do multitask smoothly. Not only that, but they also boost the performance of heavy apps.

Cache

The cache copies most frequently visited data and stores them so that you can access them quickly. There are three cache memories you’ll find where the fastest is L1, but it’s squeezed. L2 has more space, but it’s slower, and L3 has ample room, but it’s much slower than others.

However, if a CPU needs data that isn’t available in these caches, it goes to the RAM, which is the slowest one. And that’s because it’s physically far away.

How to Install LGA 1151 CPU?

Well, installing socket 1151 processors is as easy as ABC. Just follow our below mentioned simple steps to get your work done with ease.

Open Load Plate

Pull up the lever to open the load plate of the plastic housing for the CPU on your motherboard. Remember to not touch the socket contact point.

Place CPU

Hold the LGA 1151 CPU by your thumb as well as the index finger. You’ll see two divots on each side of it. Drop it in the plastic housing without sliding or tilting. And make sure that you align the socket notches along with the processor notches.

Remove Protective Cover

Now, remove the cover from the load plate but don’t throw it away. Whenever you remove the processor from the socket, you can replace it with the cover.

Close the Load Plate

You’ll need to apply a little amount of force for closing the load plate. Just hold it down and pull down the socket lever.

Top 2 LGA 1151 CPU Brands in The Market

There are two CPU brands that totally lead the industry. They both have advantages and some minor issues. We’re going to give a brief discussion on both of them.

Intel

As single-core performance is vital for gaming, Intel has been leading for a long time to provide such benefits. In fact, it was the only choice for users to build PCs. Besides, if you talk about overclocking, this brand is superior in this regard too. Intel has been providing this advantage for a prolonged time.

However, you can only overclock the CPUs that are marked with a “K” at the end of the model number.

The only drawback that you are very likely to face with Intel CPU is that you may have to buy a new compatible motherboard during upgrading.

AMD

It was after 2010 when AMD got into the real competition and started to give a good fight with Intel. Most of the AMD Ryzen CPUs offer higher numbers of core and thread as well as multithreading benefits.

And the best part is that it was quite cheaper and came with brilliant stock coolers. If you talk about compatibility, AMD leads in this regard. As almost all the CPUs of AMD use AM4 socket, so you won’t need to buy a separate motherboard.

However, it moves back when it comes to per-core performance, which is vital for delivering quality gaming performance.

Frequently Asked Questions (FAQs)

1. How many pins does LGA 1151 have?

LGA 1151 has 1151 sticking out like pins. They assist the CPU in creating contact with the pads placed on the processors.

2. Are all the LGA 1151 sockets similar?

The width and height of the socket of LGA 1151 and 1150 are the same. Yet, you can’t physically fit the 1151 socket into the 1150 and vice versa.

3. How do I know if my new LGA 1151 is going to work with my motherboard?

Go to the mobo manufacturer’s website to check. There you’ll find a page that consists of the list of CPUs compatible with your motherboard. However, you may need to install particular BIOS on your motherboard for some CPUs to work.

4. How do I know if my CPU is dead?

If your computer gives a beep sequence or doesn’t boot to bios, then it’s probable that the CPU is dead. You’ll see these symptoms while turning on the computer.

5. Is GPU bottlenecking bad for gaming?

GPU bottlenecking is good when you’re gaming. That’s because your CPU can process all the game and frame data quite faster than your GPU. As a consequence, you get to utilize your GPU completely.

Final Words

Well, now you have the best LGA 1151 CPU that you can get in the market. Every item was examined carefully so that you get what you pay for. It would be better for you to buy a CPU depending on where and how you plan to use it.

Because at the end of the day, it all depends on whether you’re buying it for mainly playing games or other use.
