What is a Graphics Card?
A graphics card, also called a GPU (Graphics Processing Unit), is a hardware component that processes and renders images, videos, and animations on your computer.
In simple words:
👉 CPU = Brain of the computer
👉 GPU = Visual engine of the computer
Main functions of a GPU:
- Renders game graphics
- Displays images and videos
- Supports high-resolution screens
- Handles 3D and visual tasks
Leading GPU manufacturers include NVIDIA and AMD.
What is GPU in PC?
A GPU (Graphics Processing Unit) is the core chip inside a graphics card that performs complex calculations for rendering visuals.
It works by:
- Processing thousands of calculations at once
- Handling graphics faster than CPU
- Improving gaming and video performance
Modern GPUs are extremely powerful and are essential for gaming PCs and high-performance systems.
Types of GPUs (Integrated vs Dedicated)
Integrated GPU (iGPU)
- Built inside processor
- Shares system RAM
- Lower performance
- Suitable for office work and basic use
Common in laptops and budget PCs.
Dedicated GPU (Graphics Card)
- Separate hardware component
- Has its own VRAM
- High performance
- Required for gaming and editing
Examples include RTX and Radeon GPUs.
What Does VRAM Mean?
VRAM (Video RAM) is memory used by the GPU to store graphics data such as textures, frames, and images.
More VRAM means:
- Better game textures
- Higher resolution support
- Smoother performance
How Much VRAM Do You Need?
2GB – 4GB
- Basic tasks
- Very light gaming
6GB
- Medium gaming
- Budget builds
8GB (Recommended)
- Modern gaming
- Best value in Pakistan
12GB+
- High-end gaming
- Video editing
- 3D work
In 2026, 8GB VRAM is considered the standard for gaming PCs.
Do You Need a Graphics Card?
You DO need a GPU if:
- You play games
- You edit videos
- You do 3D work
- You want high performance
You may NOT need a GPU if:
- You use PC for office work
- You browse internet
- You watch videos
Integrated graphics are enough for basic tasks.
GPU for Gaming vs Normal Use
Gaming GPU
- High FPS
