Hey, I've came across to an interesting question. It's 

What is framebuffer in GPU?
a) a module for the final image processing
b) rendering unit
c) video memory

Honestly, I've got no idea.  Does anyone know?

Yes, I've already googled the question. But wiki does not give an accurate answer. I don't really understand this problematic, so I thought I might try amd forums?

Well, look at a it the same way you would look at any other compound word, by breaking it down into it's constituent parts:

Frame: A completely rendered image.
Buffer: A temporary storage area for data being transmitted between two devices that function at different speeds.

So a frame buffer is a temporary storage area where fully rendered images (frames) are held until they are able to be displayed on the monitor. In terms of gaming, you can think of the entirety of the VRAM as functioning as a frame buffer.
