CPU vs. GPU: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 19, 2023
A CPU (Central Processing Unit) manages all computer operations, while a GPU (Graphics Processing Unit) accelerates graphics and parallel tasks.
Key Differences
The CPU, or Central Processing Unit, often termed the "brain" of the computer, handles most general-purpose tasks and manages system operations. It ensures smooth functioning of software, user commands, and the operating system. The GPU, or Graphics Processing Unit, is specialized hardware mainly designed for rendering graphics and handling complex computations in parallel.

CPU architectures are optimized for tasks that require sequential processing, ensuring efficient execution of a wide variety of instructions. In contrast, the GPU's architecture focuses on parallelism, enabling it to process many calculations simultaneously, especially useful in graphics rendering where thousands of pixels are processed at once.

Most computers, whether desktop or laptop, will contain a CPU to manage standard operations. The presence of a GPU might be more variable. While all systems will have some form of graphics processing, dedicated GPUs are commonly found in gaming rigs or workstations that handle graphic-intensive tasks. On the other hand, CPUs are essential for all systems and are responsible for running the primary processes.

A CPU tends to have fewer cores (think of these as processing units) than a GPU. This distinction allows CPUs to be better at tasks that can't be easily broken down or parallelized. Conversely, GPUs might have hundreds or even thousands of smaller cores, making them suitable for tasks that can be divided and executed simultaneously, such as shading different pixels in an image.

While both CPU and GPU are integral parts of computer architecture, their roles and strengths are distinct. The CPU manages and delegates, ensuring all parts of the system work together effectively. The GPU, in contrast, takes on specialized tasks that benefit from parallel processing, offering acceleration especially in graphical endeavors.

Cpu
The central processing unit, that part of the electronic circuitry of a computer in which the arithmetic and logical operations are performed on input data, which are thereby converted to output data; it is usually located on the mainboard, or motherboard, of a computer. The CPU and the memory form the central part of a computer to which the peripherals are attached. Most personal computers as of 1998 had only one CPU, but some computers may have more than one CPU.
