AMD's Radeon HD 6870 benchmarked? (updated more screens)

I can tell you about normal CGI rendering, which shares a lot of similarities.

Displacement takes quite a lot of time to render and when the resolution is smaller, rendering goes faster. If you leave the same displacement and up the res, you increase linearly the rendering time, because the objects being displayed/rendered share a bigger pixel space. Displacement is done on screen, not for the whole scene, it would be crazy to do it like that.

Well... CGI rendering is actually quite different from the graphics cards rendering pipeline.
Take a look at this:

From Input Assembler until after the Geometry Shader everything is done resolution independent! (as somebody mentioned assuming same aspect ratio) The Rasterizer and Pixel Shader are then operating on the actual pixel level of the current rendering target.
