Who Makes CPUs: The Two Major Companies Behind

CPUs, or central processing units, are a fundamental part of any computer. They’re responsible for handling the basic instructions that tell the computer what to do. As such, they form the backbone of your machine and affect its performance in a variety of ways. So who makes CPUs? Let’s take a look.

Who Makes CPUs?

The central processing unit (CPU) is the hardware component in a computer that carries out the instructions of a computer program by performing the basic arithmetic, logic, and input or output (I/O) operations specified by the instructions. The CPU is also sometimes referred to as the microprocessor or processor. AMD and Intel are the two major manufacturers of CPUs for computers. Both companies have three general lines of processors: budget, mainstream, and high-end.

In all cases, a computer’s CPU must be compatible with the motherboard, memory, power supply, and graphics cards. Budget processors are low-cost and have fewer features than mainstream or high-end processors. Mainstream processors are more powerful and have more features than budget processors. High-end processors are the most powerful and have the most features. 

What is the Purpose of CPUs?

CPUs are essential for computing devices because they calculate and interpret instructions. In other words, the CPU is responsible for carrying out the commands of software programs. CPUs are sometimes referred to as “the brains of computers” because they play such a vital role in the operation of computing devices. CPUs are made up of two main parts: the control unit and the arithmetic logic unit. 

The control unit is responsible for fetching instructions from memory and decoding them so that they can be executed by the arithmetic logic unit. The arithmetic logic unit, on the other hand, performs arithmetic and logical operations. Together, these two units work together to carry out the instructions of software programs. 

Why is the CPU Most Important?

The processor, or CPU, is the most important component of any computer. It provides the instructions and processing power [1] that the computer needs to do its work. The more powerful and updated your processor, the faster your computer can complete its tasks. In addition, a more powerful processor can also help your computer think and work faster. For these reasons, it is important to choose a CPU that is powerful enough to meet your needs.

When choosing a new processor, be sure to consider the type of tasks that you will be using it for. If you plan on doing a lot of video editing or other resource-intensive tasks, you will need a more powerful processor than if you plan on doing general office work or surfing the web. 

What Are CPUs Made Of?

Today, CPUs are made mostly of an element called silicon. If you’ve ever seen a computer chip, it probably looks like a dark circle with a bunch of metal leads sticking out of it. The flat, dark part of the chip is made of silicon. In fact, the word “silicon” comes from the Latin word for “flint,” because flinty quartz rock looks very similar to raw silicon. And like flint, silicon can be used to create sparks when it’s struck with metal.

Silicon is actually pretty common in Earth’s crust. But what makes silicon special is that it’s a semiconductor. This means that depending on what materials you add to it, it can either conduct electricity or insulate against it. This makes silicon the perfect material for computer chips. When electrical current is passed through a silicon chip, it can switch between two states: on and off. 

In other words, it can be used to store information in the form of binary code (ones and zeroes). That’s how computers are able to perform complex calculations and process large amounts of data.

What Makes CPU Faster?

When it comes to processing speed, clock speed is king. A higher clock speed means a faster CPU. However, many other factors come into play as well. Your CPU processes many instructions (low-level calculations like arithmetic) from different programs every second. The clock speed measures the number of cycles your CPU executes per second, measured in GHz (gigahertz). But even with a high clock speed, your CPU can become bogged down if there are too many instructions to process. 

This is where other factors come into play, such as the number of cores (the brains of the operation) and cache size (a high-speed memory bank that stores frequently used instructions). In general, the more cores and the larger the cache, the faster your CPU will be. So when shopping for a new CPU, make sure to take all of these factors into account.


In conclusion, CPUs are vital to any computer and come in different shapes and sizes from two major manufacturers, AMD and Intel. They have different general lines of processors that must be compatible with the motherboard, memory, power supply, and graphics cards. CPUs are made mostly of an element called silicon and what makes CPUs faster is a higher clock speed which measures the number of cycles your CPU executes per second.
