What Makes the CPU, GPU, RAM, and Hard Drive Tick?
Have you ever wondered what goes on inside your computer’s hardware when you’re running a program or playing a game? Have you ever been curious about the inner workings of your CPU, GPU, RAM, or hard drive? Well, wonder no more! In this blog post, we’ll explore what makes these components tick and how they work together to give us the computing power we rely on every day.
Central Processing Unit (CPU)
The CPU, or central processing unit, is often referred to as the brains of a computer. It’s a small chip that sits on the motherboard and is responsible for processing and executing instructions. The CPU is divided into two main parts, the control unit and the arithmetic logic unit.
The control unit manages the flow of data between the CPU and other components of the computer. It also fetches instructions from memory and executes them. The arithmetic logic unit performs mathematical and logical operations, such as adding and subtracting numbers or comparing data.
The CPU uses a clock to synchronize the execution of instructions. The clock sets a steady pace for the CPU to follow, and each tick of the clock represents one instruction cycle. The speed of the clock is measured in gigahertz (GHz), and the higher the clock speed, the more instructions the CPU can execute per second.
CPU Comparison Chart
CPU | Cores | Threads | Base Clock Speed | Max Boost Clock Speed
— | — | — | — | —
Intel Core i5-10600K | 6 | 12 | 4.1 GHz | 4.8 GHz
AMD Ryzen 9 5950X | 16 | 32 | 3.4 GHz | 4.9 GHz
Apple M1 | 8 | 8 | 3.2 GHz | 3.2 GHz
Graphics Processing Unit (GPU)
The GPU, or graphics processing unit, is responsible for rendering images and video on your computer’s screen. It’s designed to handle the complex mathematical operations required for 3D graphics and video processing.
Modern GPUs are highly parallelized, meaning they can perform multiple operations at once. They’re also optimized for floating-point operations, which are used for calculations involving decimal numbers.
One of the key features of a GPU is its ability to transfer data quickly between the GPU’s own memory and the computer’s main memory. This is known as bandwidth, and it’s crucial for handling the large amounts of data required for high-quality graphics and video.

GPU | Cores | Base Clock Speed | Max Boost Clock Speed | Memory Type
— | — | — | — | —
Nvidia GeForce RTX 3080 | 8704 | 1440 MHz | 1710 MHz | GDDR6X
AMD Radeon RX 6900 XT | 5120 | 2015 MHz | 2250 MHz | GDDR6
Random Access Memory (RAM)
RAM, or random access memory, is a type of volatile memory that stores data temporarily while your computer is running. It’s essentially your computer’s short-term memory, and it’s used to hold data and instructions that are currently in use by the CPU.
The primary advantage of RAM is its speed. Because it’s located on the motherboard, it’s much faster for the CPU to access than data stored on a hard drive or solid-state drive.
RAM is measured in gigabytes (GB), and the amount of RAM you need depends on the types of programs you run. If you’re a heavy multitasker or you work with large files like videos or images, you’ll likely need more RAM than someone who primarily uses their computer for email or web browsing.
RAM Comparison Chart
RAM | Type | Speed | Capacity | Price
— | — | — | — | —
Corsair Vengeance LPX DDR4 | DDR4 | 3200 MHz | 16 GB (2 x 8 GB) | $79.99
G.Skill Ripjaws V DDR4 | DDR4 | 3600 MHz | 32 GB (2 x 16 GB) | $159.99
Crucial DDR3 1600 | DDR3 | 1600 MHz | 8 GB (2 x 4 GB) | $44.99
Hard Drive (HDD) and Solid State Drive (SSD)
The hard drive, or HDD, is the traditional form of storage for desktop and laptop computers. It uses spinning disks to store data magnetically, and it’s known for its relatively low cost per gigabyte of storage.
However, the hard drive is limited by its mechanical nature. Because it has moving parts, it’s slower to access data than a solid-state drive (SSD). It’s also more prone to failure, as the mechanical components are subject to wear and tear.
The solid-state drive (SSD) is a newer type of storage that uses flash memory to store data instead of spinning disks. SSDs are known for their speed, as they can access data almost instantly. They’re also more reliable than hard drives, as they have no moving parts.
One downside of SSDs is their cost. They’re typically more expensive per gigabyte of storage than hard drives, although the price has been coming down in recent years.

Seagate BarraCuda HDD | 2 TB | $54.99 | 210 MB/s | 580 MB/s
Samsung 970 EVO SSD | 1 TB | $179.99 | 3500 MB/s | 2500 MB/s
Conclusion
In conclusion, the CPU, GPU, RAM, and hard drive are the four key components that make up a computer’s hardware. Each component plays a crucial role in processing data and executing instructions.
The CPU serves as the central hub of the system, managing data flow and executing instructions. The GPU is responsible for rendering 3D graphics and video. RAM provides short-term storage for data and instructions that are currently in use by the CPU. And the hard drive or SSD provides long-term storage for all the data on your computer.
Understanding how these components work together can help you make informed purchasing decisions when it comes to upgrading or building a new computer. It can also help you troubleshoot issues and optimize your system for peak performance.
So, the next time you’re using your computer, take a moment to appreciate all the complex processes and calculations that are happening behind the scenes, thanks to these amazing components.
