A graphics card (also called a GPU — Graphics Processing Unit) is responsible for generating the images displayed on your screen. Every computer has one — the question is whether it's a dedicated card or integrated into the processor.
Integrated vs dedicated graphics
Integrated graphics (Intel Iris, AMD Radeon integrated) are built into the processor. They share system RAM and are perfectly adequate for everyday tasks — web browsing, video streaming, office work, and even older or less demanding games. Dedicated graphics (NVIDIA GeForce, AMD Radeon) are separate cards with their own video memory. They're essential for demanding 3D games, video editing, 3D modelling, and machine learning tasks.
Do you need a dedicated graphics card?
You probably don't if you: primarily browse the web and use office software, watch streaming video (Netflix, YouTube), do basic photo editing in Lightroom or Photoshop, and don't play games (or play older/less demanding games). You likely do need one if you: play modern 3D games, edit video in 4K, work with 3D software (CAD, Blender), or use AI image generation tools.
Can you upgrade the graphics in a laptop?
In almost all cases, no. Laptop GPUs are soldered to the motherboard and cannot be replaced. This is one reason to buy a laptop with the right graphics specification from the start if you have demanding needs.
