What’s The Difference Between a Laptop CPU and a Desktop CPU?

Are you in a quandary over the flashy allure of a gaming laptop or the brute force of a desktop PC? The long-standing conflict between the two types of CPUs persists, with each presenting distinctive advantages and disadvantages. So, what sets apart a laptop CPU from a desktop CPU?

Desktop CPU

Though both laptop and desktop CPUs perform comparable functions, they are engineered for different use cases. Laptop CPUs prioritize energy efficiency and compactness, while desktop CPUs prioritize performance and power. However, it’s not as simple as that. So let’s delve deeper into the disparities between the two.

Is a Desktop CPU faster than a Laptop CPU?

Generally speaking, desktop CPUs are swifter than laptop CPUs. This is due to their larger physical dimensions, superior thermal capacities, and more available power, enabling higher clock speeds and more cores.

Furthermore, desktop CPUs are typically unrestrained by thermal and power limitations, as they are equipped with larger heat sinks and fans and powered by desktop power supplies. This grants them the capability to operate at higher clock speeds and maintain them for longer durations. High-end desktop CPUs can accommodate more cores, which allows them to multitask more efficiently without sacrificing productivity.

Conversely, laptop CPUs are devised to be more energy-efficient to preserve battery life and generate less heat. They are generally smaller in size, have lower clock speeds, and have fewer cores than their desktop equivalents. Therefore, they may not be as rapid as desktop CPUs in tasks that necessitate extensive processing power, such as video editing, 3D rendering, or gaming.

Nevertheless, laptop CPUs have progressed significantly. More potent models do exist. You would be surprised to learn that many high-end laptops have processors that are not too far behind desktops in terms of performance. For instance, Intel CPUs with an H designation, such as the Intel® Core™ i7-10750H, offer a superior gaming experience on a laptop.

What are the Key Differences between a Desktop CPU and a Laptop CPU?

Desktop and laptop computers utilize different types of CPUs to execute computations and operate programs. While they serve the same fundamental purpose, the two have several fundamental differences. Comprehending these distinctions can assist you in selecting the ideal type of computer for your needs and guaranteeing the best performance and experience from your device.

Form Factor

The principal form factor difference between a desktop CPU and a laptop CPU is size and portability. Desktop CPUs are utilized in larger computers, providing more space for additional features, such as higher clock speed and more cores.

Hence, they offer better performance than laptop CPUs. However, this increased performance comes at the expense of portability, as desktop computers are significantly more substantial and bulkier than laptops.

Conversely, laptop CPUs are optimized for power efficiency and heat management, allowing them to be utilized in smaller and more portable devices. Thus, it’s up to you to decide what you prioritize: performance or portability.

Power Consumption

Laptop CPUs are engineered to be more energy-efficient to conserve battery life. They typically consume less power and generate less heat.

CPU power consumption

On the other hand, desktop CPUs are engineered to deliver more performance, so they consume more power. They are generally larger and have more room for additional components, such as more extensive cooling solutions, allowing them to run at higher clock speeds.


Because of the difference in their design and size, laptop and desktop processors differ significantly in their cooling capabilities.

Since desktop CPUs have more cooling headroom, they can easily be fitted with a more powerful aftermarket cooler, which can provide better cooling performance.

This makes it possible for them to run at higher clock speeds longer without overheating. 

Laptops, on the other hand, are designed for portability. While that offers many benefits, their small body limits airflow.

To make up for the lack of space, laptop manufacturers usually use smaller and less powerful cooling systems optimized for energy efficiency rather than cooling performance. That’s why their cooling capabilities aren’t as good. 

This can lead to overheating and performance issues if the laptop is used for extended periods or high-demand applications. Unlike desktops, it isn’t possible to replace the internal cooling system of a laptop. The best you can do is buy a cooling pad for it.


Because of the laptop’s compact design, manufacturers are forced to cut corners to make all the hardware fit inside. As a result, its small size limits the number of transistors that can be packed onto the chip, limiting the CPU’s performance capabilities.

Power consumption is another factor. To reduce power consumption, laptop CPUs are often underclocked or limited in other ways to prevent them from overheating or draining the battery too quickly. Desktop CPUs don’t have the same power limitations.

They can run at full capacity for extended periods of time without issue.

Plus, desktop CPUs have higher clock speeds and more cores than laptop CPUs, which enables them to perform tasks more quickly and efficiently.

This is particularly important for resource-intensive applications such as gaming, video editing, and scientific simulations, which require a lot of processing power to run smoothly.


Upgrading a desktop CPU is often as simple as removing the old CPU from its socket and installing a new one. Of course, you need to make sure it’s compatible with your other hardware. Unfortunately, upgrading laptop hardware isn’t as easy. 

Since they have a more compact and lightweight design, their internal components are often tightly packed together and may not be easily accessible.

Upgrading a laptop CPU typically involves disassembling the entire unit, which can be time-consuming and challenging. 

Additionally, the CPU is soldered directly onto the motherboard on newer models, making it impossible to replace. Even if you are able to upgrade the CPU, you may also need to get a new motherboard to ensure compatibility. It will be easier and more affordable to just buy a new one. 


Desktops are generally less expensive than laptops because their components, including CPUs, are mass-produced and can be easily swapped out, which results in lower costs.

In contrast, laptop components are often smaller and more specialized, which can lead to higher production costs. Desktops also have larger cases for better cooling, reducing the need for expensive thermal solutions.

Furthermore, desktops usually don’t include additional components, such as monitors, keyboards, and mice, that laptops come with. So when purchasing a desktop, you can opt for less expensive peripherals, which can help keep the overall cost down.

Is It Worth It to Get a Gaming Laptop Instead of a PC?

You’ve probably heard this one too many times. But it really does depend on your needs. The biggest advantage of laptops is their portability. If this isn’t a big deal for you, then a desktop should suffice. Not only do desktops offer better performance than gaming laptops, but they also cost less.   

But if you’re always on the move and want to bring your computer wherever you go, you can rest easy knowing that gaming on a laptop is possible. It is more expensive, but it is viable.  

If you’re not too sure what to get, you can check out websites that do CPU benchmarking. Unlike desktops, laptops aren’t that customizable.

So what you see is often what you get. If it can meet the performance you’re after on a computer, why not game on a laptop? But even though gaming laptops are the bulkiest laptops around, there just isn’t enough space for good airflow. So make sure to invest in a cooling pad as well. 

Let’s do a quick summary and take a look at the pros and cons of owning a gaming laptop. 


  • Portable
  • Stylish design
  • Can handle hardware-intensive games
  • Takes up less space
  • Everything in a single machine


  • Expensive
  • Poor battery life
  • Prone to overheating and noise
  • Difficult to upgrade
  • Limited storage
  • Heavier and bulkier than a regular laptop

Final Thoughts

Whether you’re a hardcore gamer, casual user, or tech enthusiast, the choice between laptop and desktop CPUs ultimately comes down to your individual needs and preferences. While desktop CPUs offer more raw power and upgradeability, laptop CPUs provide greater portability and convenience. So, the next time you’re faced with the age-old question of laptop vs. desktop, carefully weigh the pros and cons and choose wisely.
