What are the differences between dedicated and integrated graphics?

[Atreyo Bhattacharjee]

I understand that integrated graphics are soldered onto the CPU and the dedicated is in the form of a PCIe card. I'm wondering what is similar and different in the processes and components used to make it?

Also, if we need DirectX and OpenGL to use our graphics cards, why not also for integrated graphics? If a program is made without utilizing those APIs, how does it run compared to a game or such that would use the APIs?

Thank you

directx and opengl work on both iGPU and dGPU. as long as they write driver for it

The biggest difference is that Integrated graphics utilize the system ram on the motherboard, while dedicated graphics supply their own memory, and don't use any of your system ram.

if you go for a laptop and want to do more thing use one that the gpu have is own dedicated ram .

Do you have a reason for your question?

The biggest difference is performance.
Integrated graphics adapters are fine for normal desktop work and movie playback.
Dedicated graphics are stronger and take more power. They are need for fast action gaming graphics.

I would not worry much about API issues. It makes little real difference, and, there is very little that you can do about it anyway.
