Integrated vs. dedicated
| Integrated GPU | Dedicated GPU | |
|---|---|---|
| Location | Inside the processor itself | Separate card |
| Cost | Included, no extra cost | Significant extra cost |
| Graphics performance | Basic, enough for office work/video | Needed for gaming and serious graphics work |
| Video memory | Shares the system's RAM | Its own dedicated memory (VRAM) |
When do you actually need a dedicated GPU?
For serious gaming, video/3D editing, or local AI work. For office tasks, browsing, and normal video playback, the integrated graphics on a modern processor are enough.
Tip: not sure how much VRAM you need for a dedicated GPU? That specific guide helps you decide based on your resolution and type of use.
The two main dedicated GPU manufacturers
NVIDIA and AMD are the two dominant manufacturers — both offer equivalent performance tiers across different price ranges, similar to the situation between Intel and AMD in processors.
Frequently asked questions
Do I need a dedicated graphics card for normal use?
No, the integrated graphics on a modern processor are enough for office work, browsing and video playback. A dedicated card is mainly needed for serious gaming or demanding graphics work.
When is it worth upgrading my PC's graphics card?
When the games or programs you use don't run as smoothly as you need, and you've confirmed the GPU (not another component) is the real bottleneck in your machine.
