Best LGA 1151 CPUs for 2023 | Top Picks and Reviews | Expert Analysis


Searching for the best LGA 1151 CPU? If yes, you are at the right place. LGA CPU is what the majority looks for when it comes to building a personal Pc. Now, we all know a CPU is the heart of every computer system. So whether it’s a gaming machine or a business one, a powerful processor is a must-have thing.

These days, even novices look for the best budget processors. They want to get the maximum performance within their budget range. That’s where this 1151 CPU really shines. This detailed guide is all about some of the best LGA 1151 CPUs of 2022. So, let us get into it!

LGA 1151? What Is It, Actually?

Most of you would be familiar with LGA 1151 CPUs. However, for beginners, here is a brief rundown. Basically, the LGA 1151 is a motherboard socket. All modern-day motherboards have it. This CPU socket is compatible with Intel microprocessors. Further, these 1151 processors aren’t hard on the pocket.

That’s why almost every gamer and casual Pc user keeps searching for 1151 Intel core i7 processors. Anyhow, we have tested a bunch of these processors. So let us help you decide which 1151 compatible Intel core i7 processor you should get.

Best LGA 1151 CPU – What Things Should You Consider?

Best LGA 1151 CPU

There are a ton of quality processors out there. For example, core i5 9600K and core i7 9700K are some of the best Intel microprocessors out there. However, as a newbie or even an expert, you should always consider several factors before buying any of these processors. So, here is our detailed buying guide to help you in this regard.

i): Clock Speed

Alongside the CPU core, the clock speed matters the most. Now, most the users think that these speeds don’t really matter. Whereas the clock speed of any processor (be core i5 9600K it or core i7 9700K) matters the most. So, never overlook this aspect while buying any CPU for your next build.

Further, the majority also confuse the term “CPU Cores” with the clock speed. In reality, they are both different aspects but are closely interlinked. For example, the quad-core processor can run multiple programs at once. At the same time, a dual-core processor with a higher clock speed may also deliver the same performance (despite having two cores).

So, you see, the dual-core processor had a higher clock speed, which helped deliver smoother performance. Ideally, it would be best if you went with at least a quad-core processor with decent enough clock speed.

ii): CPU Cores and Threads 

Now, comes the CPU cores. Often, these cores are mixed with the clock speed. Note that they both are different terms. The CPU cores are basically individual mini-processors. They are an essential component of the main processor and help it run multiple tasks at the same time.

For instance, the dual-core processor is actually a single chip. However, it has two cores which double its performance. On the other hand, the CPU thread helps it execute different sequence instructions. Usually, hyperthreaded processors are liked by the majority. These processors are also quite efficient.

iii): TDP – Thermal Design Power

Thermal design power says a lot about any particular processor’s processing power and efficiency. Now, why it’s important? Well, that’s because less TDP value means the processor will emit less heat.

These days, many processors come with an in-built cooling system. Moreover, these processors are considered quite snappy. But that’s not the case anymore.

Intel processors are usually known for their excellent efficiency. That’s because these CPUs don’t exhibit as much heat as some other microprocessors do.

iv): IGP (Integrated Graphic Processor)

IGP is another term (or aspect) that you should look for in a CPU. This term basically means the graphics processing unit (GPU) that comes integrated within the microprocessor. For example, most of the latest Intel processors come with an integrated GPU. Even with the IGP, these processors are quite good at emitting maximum heat.

For instance, the 9th generation core i3 9100 f also has an integrated GPU. So, that’s a good pick for daily use. This is another term you should be aware of before buying any 1151 CPU.

v): Turbo Frequency

The turbo frequency of a CPU also speaks of its performance. Now, most of the affordable CPUs don’t have support turbo frequency. Whereas buying a processor with a specific turbo frequency is always a good idea. This frequency allows the CPU to operate at a slightly higher clock speed when the maximum power output is required.
