Detailed Description

Renderbuffers provide the images that can be rendered to by attaching them to the framebuffer as color or depth stencil images.

Unlike textures, you cannot access renderbuffers using the samplers from shaders. When you direct rendering to a framebuffer, the depth and stencil tests require either renderbuffer or texture attached to the framebuffer.

You can read the content of renderbuffers with the ReadPixels() function.
