What Makes a Great LGA 1151 CPU? 

The type of CPU you pick for your computer will determine its speed and efficiency. Below we discuss five important factors you want to consider while shopping for an LGA 1151 CPU.

Processor Core Numbers

You should consider finding a processor with at least four cores. If you can afford a CPU with threads double the number of cores it would even be better for multitasking and heavy workloads.

Remember, for an average gaming PC, single-core performance would serve just fine.

Consider the IGP

A good Integrated Graphics Processor (IGP) guarantees quality picture resolution and good motion. Good CPUs come with at least Intel UHD Graphics 610 and Intel HD Graphics 630. You should also consider a clock speed of at least 3.6GHz. However, a good gaming rig requires a dedicated graphics card (GPU) for the best gaming performance.

CPU Turbo Frequency

A good LGA 1151 CPU has a high-operation speed. This is important to prevent the system from overheating. A base clock speed of about 3.6GHz with a boosting capability should serve well for either gaming or multitasking.

Power and Thermal

For intense uses like gaming and other productivity tasks, consider a CPU with high wattage of between 54 and 90 watts. This way, your system will run cool and consume less electricity while still offering great performance.

Cache Memory

The larger the cache memory the better. A 6 MB memory and above is desirable. Bigger cache storage means your software will be able to shift data fast without having to go back to the computers' main memory from time to time to retrieve information.

Of course, computers are not made exclusively for fun. LGA 1151 also makes for a good CPU for basic browsing and other productivity tasks like office work, which is why some LGA CPUs like Intel Core i5-6500 have low cores of about 4 for less intense tasks.

Aspects to Consider Before Buying 

Shopping for the right CPU can be an uphill task if you are not sure about what to look out for. Here are the top three aspects you might need to consider.

Intended Purpose of the CPU

Determine what you are getting a CPU for. Is it for basic browsing and sending emails? Or are you shopping for a CPU for high-end use like video editing and other demanding tasks like immersive gaming?

The former will not need a powerful CPU to execute tasks. For gaming and other multitasking needs, you'll need a high-end CPU with more cores and threads.

Intel or AMD

Until 2020 there were only two players in CPU manufacturing: Intel and Advanced Micro Devices (AMD).

While Intel CPUs offer great single-core performance suitable for gaming enthusiasts, AMD competes closely by compensating with more cores in their chips.

Despite the close competition from these two manufacturers, they both offer great processors. It all narrows down to other factors like price and other personal preferences.

Right CPU for the Right Socket

As we've seen, different LGA 1151 CPUs come with varied specifications in terms of pin-count. Before buying a CPU, pay keen attention to the compatibility of the motherboard pin count and CPU sockets.

Advanced Micro Devices (AMD) CPUs have pins on the CPU and sockets on the motherboard, the opposite is true with Intel CPUs.

Note: Just because a CPU fits into a socket on a motherboard does not mean it will be compatible.

Installing an LGA 1151 CPU

The procedure for installing both AMD and Intel CPUs is simple and follows the same steps, although Intel CPUs have pins on the motherboard while AMD CPUs have pins on the CPU and sockets on the motherboard.

Below are steps for the successful installation of a CPU:

  1. Locate the CPU socket on the motherboard and pull retention arms just beside the CPU socket to access the socket region. Intel has a socket cover but for AMD CPUs, the socket cover is absent. 

  2. Pull out the CPU from its package and take note of the arrows to establish which way to properly align the CPU.

  3. Lower the CPU into the sockets with zero insertion force.

  4. Close down the lid by fixing the retention arm back in position.

  5. Apply thermal compound on top of the CPU where it's going to attach to the fan.

  6. Align the fan with the four holes in the corners and press down each at a time with a little force.

  7. Plug in the fan and power the system up. The position of the sticker on the fan should not matter.

  8. Your CPU is now successfully installed and ready to work.

Be sure to watch the video below for a more elaborate insight into the installation process we've just described.
