This post and like the next 3 posts after it are all wrong. First off TMU's are not Texture memory units, they are texture mapping units, though they do have large amounts of cache associated to them.

This too is wrong, why would you have TMUs if they are not doing the texture processing? Maybe you are confusing offloading AA work from RBE's into the shaders, but this is not occurring with TMUs yet.

Its been shown that there is nothing wrong with Ati's AA in and of itself, in fact the hit from just AA is often less than nvidias at the same setting. Its AF that tanks performance. The source below shows this, especially with HQAF which is default for Ati now. If you want old AF you need to use ati tray tools or other progs like that.
