How Is Laptop Speed Measured? (Explained for Newbies)

| Updated:

Computer processors and their clock speeds are two characteristics most commonly associated with laptop speed. When comparing computers, one of the most important factors to consider is CPU speed. Because the CPU is the brain of your laptop, ensuring it works optimally is critical to your laptop’s functionality. 

Understanding how the speed of a laptop is measured starts with understanding what a processor does and how other internal components improve your laptop’s speed. Let’s look at how laptop speed is measured, break down some important components and highlight how to increase the speed of your laptop. 

How Is the Speed Of A Laptop Measured?

Two key factors determine a laptop’s overall speed: the CPU’s clock speed and the amount of data that the CPU can process at a time.

Moreover, the clock rate is the speed the CPU executes instructions. Every computer has an internal clock that controls the rate tasks are executed. Furthermore, the internal clock synchronizes various internal components. The Central Processing Unit requires a fixed number of clock ticks to process instructions on the computer.

The more tasks the CPU can execute per second, the faster the clock speed. Clock speed is measured in gigahertz (GHz) or megahertz (MHz). Mega means million, and hertz means time per second, so 100 MHz equals 100 million times per second, and 100 GHz is 100 billion times per second.

Moreover, the CPU’s internal architecture influences its performance just as much as its clock speed. Another factor that impacts the laptop’s speed is the cache and primary memory size. If you run multiple applications simultaneously or work with large files, increasing the primary memory’s size will improve performance.

Lastly, the cache is a small amount of high-speed memory located on or near the CPU. Cache memory stores the most frequently requested tasks and data for the CPU.

What Are Clock Speed and Processor Core?

Clock Speed and Processor Cores are two interdependent components of the CPU that work together to improve processor speed and boost the performance of the laptop.

A processor core is a single processing unit inside a computer’s central processing unit. The processor core receives instructions from a computing task, uses the clock speed to process the instruction rapidly, and temporarily stores it in RAM before saving it permanently to the hard drive.

Most laptops have multiple cores, which allows you to complete multiple tasks simultaneously. A CPU’s clock speed determines how fast the CPU retrieves and interprets commands. The clock speed increases as the value increases. However, it is hard to increase the clock speed. As a result, more processor cores are included to boost the laptop’s performance.

How to Increase Laptop Speed 

Here’s how to make your laptop faster:

Close Unused Browser Tabs

If your browser is open often, keeping the number of open tabs to a minimum can help boost load times and improve speed. Keep in mind that the more tabs you have open, the greater the strain on your RAM and processor.

Restart Your Laptop

Restarting your laptop every now and then can help more than you think. Restarting erases the temporary cache memory and reduces strain on the CPU. 

Monitor Startup Apps

Startup programs silently accumulate over time, affecting your laptop’s boot time and overall performance. These applications use your system’s resources, sometimes without your knowledge. On Windows, you can check the startup programs that clicking Ctrl + Shift + Esc. On Mac, navigate to System Preferences > Users & Groups > Login Items to view the list of startup apps. 

Uninstall Unused Programs 

Uninstalling programs you don’t use is a simple yet effective way to enhance your laptop’s speed. Go through your list of programs, and if you discover a program you hardly use, you can uninstall the app. This increases the system’s disk space and frees up more resources, increasing laptop speed. 


The processor speed is the main factor in a laptop’s overall performance. Moreover, the clock speed of the laptop is measured in megahertz and gigahertz. The higher your laptop’s clock speeds, the quicker the performance. So, keep that in mind if you’re looking to purchase a new laptop.

Frequently Asked Questions

How Fast Should My Laptop Be?

When determining a computer’s speed, the processor and RAM are the two major components. Processing speed is measured in gigahertz (GHz), while RAM is measured in gigabytes (GB) or terabytes (TB). 

Most people’s daily tasks don’t require much power, and even the slowest processors in newer computers are adequate. For instance, a laptop with 4 GB of RAM and an Intel Celeron processor would conveniently play movies, surf the web, and perform basic productivity tasks.

How fast should my processor be to run the latest games?

When purchasing a laptop, one of the main considerations is the type of processor installed. Moreover, manufacturers now offer different laptop grades to consumers, ranging from low-end to mid-range to high-end devices. 

One way to determine how quickly a laptop can perform certain tasks is to look at its GHz number, which reflects the number of clock cycles the processor performs in one second. This indicates how quickly it processes information. More clock cycles or higher GHz numbers will result in faster performance, especially if you perform graphics-intensive tasks such as video editing, 3D modeling, gaming, etc.

How does processing speed affect battery life?

The main factor influencing battery life on laptops is power consumption. The battery capacity can change, but how much power is consumed by the laptop remains constant, even if you use it with the lid closed or while playing games.

It is best to avoid laptops with low-speed processors because they may drain your battery in a shorter time than high-end laptops that consume more power due to their intense processing requirements.
