The difference between integrated and discrete graphics is where the GPU lives: integrated graphics are built into the CPU and share system RAM, while discrete graphics (a dedicated graphics card or discrete GPU) are a separate chip with their own video memory (VRAM), power and cooling. Discrete graphics are much faster; integrated graphics use less power and cost nothing extra.
What is integrated graphics?
Integrated graphics is a GPU built into the same chip as the CPU. Examples are Intel UHD and Intel Arc integrated graphics, AMD Radeon 780M/890M in Ryzen processors and the GPU inside Apple M-series chips. Integrated graphics borrow part of system RAM as video memory; see what shared GPU memory is.
What is discrete graphics?
Discrete graphics is a separate graphics processor with its own VRAM, power delivery and cooler. In desktops it is a graphics card in a PCIe slot, such as an NVIDIA GeForce RTX 5060 or AMD Radeon RX 9060 XT. In laptops it is a separate GPU chip on the motherboard.
What are the differences between integrated and discrete graphics?
There are 6 differences between integrated and discrete graphics:
| Attribute | Integrated graphics | Discrete graphics |
|---|---|---|
| Location | Inside the CPU | Separate card or chip |
| Memory | Shared system RAM | Dedicated VRAM (8–32 GB) |
| Performance | Light gaming, video | Modern AAA gaming, 3D, AI |
| Power draw | 15–65W shared with CPU | 75–575W |
| Heat and noise | Low | Higher |
| Cost | Included with CPU | $250 to several thousand dollars |
Is integrated graphics good enough for gaming?
Integrated graphics is good enough for esports and older games at 1080p low to medium settings. Modern AMD Radeon 780M/890M and Intel Arc integrated graphics run games like Valorant, CS2, Fortnite and Minecraft at playable frame rates. New AAA games need discrete graphics.
Who needs discrete graphics?
You need discrete graphics for 4 kinds of work:
- Modern AAA gaming at 1080p high settings or above.
- 3D rendering and video editing in Blender, DaVinci Resolve or Premiere Pro.
- AI and machine learning; see GPUs for AI and cloud.
- High-resolution, high refresh rate monitors, such as 1440p 165 Hz or 4K gaming.
Can you use integrated and discrete graphics together?
Yes. Laptops switch automatically between integrated and discrete graphics with NVIDIA Optimus or AMD SmartShift/Switchable Graphics to save battery. On desktops, plug the monitor into the graphics card, not the motherboard, to use discrete graphics.
How do you know if you have integrated or discrete graphics?
You know whether you have integrated or discrete graphics by opening Task Manager > Performance. Two GPUs mean you have both. Read how to see what graphics card you have.
Can you add discrete graphics to a PC with integrated graphics?
Yes. You can add a discrete graphics card to most desktops with a free PCIe x16 slot and a power supply strong enough for the card. Small prebuilt PCs may need a low profile graphics card. Laptops can use an external GPU.
FAQ
Is a discrete GPU better than integrated?
Yes, for performance. A discrete GPU is many times faster than integrated graphics.
Does integrated graphics use RAM?
Yes. Integrated graphics reserve part of system RAM as video memory.
Is a discrete graphics card the same as a dedicated GPU?
Yes. Discrete graphics card, dedicated GPU and dedicated graphics card all mean the same thing.
