Anyone have a better article addressing the question in the title? This one felt more like a grab bag of basic terminology with a little bit of history thrown in - less how they work and more of how to compare specs of related cards.

As an aside, untextured polygons is making a huge comback as an art style. I can't think of it even having been common in early era of GPU's like the article suggests. I personally really like the look but it could end up over used just like other lofi styles. Strangely it's referred to as "low poly" even though the defining feature is lack of textures and often the poly count is fairly high, it's just not hidden from view.
