Well, here's an interesting way to explain how graphics cards work.

As the shaders showed above, each freak'n pixel-color has to be calculated. The color is usually the result of several textures, nearby lights, reflections, shadows, and maybe some more techniques. Imagine one Umpa Lumpa had to draw all the pixel-bricks(one by one), and then stack them on each other one by one? Obviously, that is not how a videocard works. No. Videocards use multiple Umpa Lumpa's. Drawing pixels and putting them in place is something that can be done perfectly seperate. Each Umpa Lumpa would be responsible for a single pixel brick. The reason this can be done in parallel is because Umpa Lumpa's don't give a **** about how other neighbor pixels are painted. They just focus on their own brick.


Unfortunately, the GPU doesn't have enough place to house up to 2 million Umpa Lumpa's that would be required for a HD screen. It would be physically impossible (so far) to manufacture such advanced GPU chips. Instead, the GPU bakeries came with some other smart tricks. Willy Wonka mutated his Umpa Lumpa's so each of them has 256, 512, or even more(!) arms. With 512 arms, you can paint 512 pixel-bricks at the same time of course.

So a single Umpa Lumpa would become responsible for a whole bunch of pixels. In nVidia land they would call such a Umpa Lumpa a "Warp” . In the AMD(ATI) bakeries they are called "Wavefronts". Different names, but the same idea.

Aside from the gross misspelling of "Oompa Loompa" it all looks very accurate.

An appropriate metaphor
Another idea I had was the spy/sniper being able to climb into the soldier's rocket launcher and be launched across the map, dealing more damage, but no splash.

so.... the real question is, how many oompa loompas does it take to run Metro 2033 at a consistent 120fps?
