What is iGPU? Understanding the Basics of Integrated Graphics Processing


When it comes to computers and gaming, graphics processing is a crucial component that determines the quality and performance of visuals. Graphics processing units (GPUs) play a vital role in rendering images, videos, and animations. While standalone GPUs are commonly used in desktop computers, laptops and some desktops have a different type of GPU known as an integrated GPU (iGPU) or built-in GPU. In this blog post, we will explore the basics of iGPU and its importance in modern computing.

What is an iGPU?

An integrated graphics processing unit, commonly referred to as an iGPU or built-in GPU, is a graphics processing unit integrated within the central processing unit (CPU) or chipset of a computer. Unlike a separate and dedicated graphics card used in a discrete GPU setup, an iGPU shares the system’s main memory and resources, offering a more compact and cost-effective solution.

How does an iGPU work?

iGPUs function by utilizing a portion of the computer’s system memory or RAM to perform graphics processing tasks. Since they are integrated within the CPU or chipset, they have direct access to the system’s memory, which allows for faster data transfer and reduced latency. They leverage the computational power of the CPU cores, enabling the system to handle both general computing tasks and graphics processing simultaneously.

The benefits and limitations of iGPU


1. Cost-effective: Since iGPUs are integrated within the CPU or chipset, there is no need for an additional graphics card, reducing the overall cost of the system.

2. Energy efficiency: iGPUs generally consume less power compared to discrete GPUs, making them ideal for laptops and energy-efficient desktops.


1. Performance limitations: iGPUs are not as powerful as dedicated GPUs, which means they may struggle with demanding graphics-intensive applications and modern AAA games at higher resolutions and settings.

2. Limited upgradeability: Unlike standalone GPUs, iGPUs are not easily upgradeable. Upgrading the graphics performance may require replacing the entire CPU or motherboard.

Uses of iGPU

iGPUs find their applications in several scenarios, such as:

1. General computing: iGPUs handle everyday tasks like web browsing, multimedia playback, and office productivity software efficiently.

2. Casual gaming: iGPUs are suitable for playing less demanding and older games, providing an enjoyable gaming experience at lower settings.

3. Multimedia and video editing: iGPUs can accelerate video decoding, encoding, and rendering, making them well-suited for multimedia tasks.


Integrated graphics processing units (iGPUs) provide an efficient and cost-effective solution for rendering graphics and visuals in computers. While they may not match the performance of discrete graphics cards, iGPUs are suitable for everyday computing tasks and casual gaming, making them ideal for laptops and energy-efficient desktops. As technology advances, iGPUs continue to improve, bridging the gap between integrated and dedicated graphics processing.
