An in-built graphics card, often referred to as an integrated GPU (Graphics Processing Unit), is a GPU that resides on the same chip as the CPU. Unlike dedicated graphics cards, integrated GPUs share system memory and are optimized for cost-effective, energy-efficient, and space-saving computing. They are widely used in laptops, desktops, and mobile devices for handling basic to moderate graphical tasks.
Key Features of In-Built Graphics Cards
1. Unified Chip Design:
Integrated GPUs are part of the CPU, reducing the need for additional hardware. This allows compact and lightweight device designs.
2. Shared Memory:
These GPUs utilize the system’s RAM for video processing, eliminating the need for separate dedicated video memory.
3. Energy Efficiency:
Designed to consume less power compared to discrete GPUs, making them ideal for portable devices.
4. Cost-Effective:
Eliminates the need for a separate GPU, reducing overall device cost.
How Integrated GPUs Work
Integrated GPUs handle tasks like rendering videos, running casual games, and processing 2D/3D graphics. Their performance is sufficient for everyday tasks such as:
Streaming videos in high definition.
Running productivity applications.
Supporting light gaming.
Applications of In-Built Graphics Cards
1. Everyday Computing:
Ideal for web browsing, video playback, and running office applications.
2. Entry-Level Gaming:
Supports games with moderate graphical requirements.
3. Content Creation:
Handles photo editing and simple video rendering tasks efficiently.
4. Portable Devices:
Powers smartphones, tablets, and ultrabooks, where space and power are limited.
Code Example: Rendering Graphics Using OpenGL
Here’s a simple example of rendering a basic shape using an integrated GPU:
#include <GL/glut.h>
void display() {
glClear(GL_COLOR_BUFFER_BIT);
glBegin(GL_TRIANGLES);
glVertex2f(-0.5, -0.5);
glVertex2f(0.5, -0.5);
glVertex2f(0.0, 0.5);
glEnd();
glFlush();
}
int main(int argc, char** argv) {
glutInit(&argc, argv);
glutCreateWindow(“Integrated GPU Rendering”);
glutDisplayFunc(display);
glutMainLoop();
return 0;
}
Advantages of Integrated GPUs
1. Lower Power Consumption: Extends battery life for laptops and mobile devices.
2. Reduced Cost: Suitable for budget-friendly systems.
3. Compact Form Factor: Enables slim and lightweight device designs.
4. Adequate for Basic Tasks: Sufficient for general-purpose computing and lightweight graphical applications.
