[quote]When looking at the actual products themselves, you can make a couple of generalizations about their performance. For starters, the GeForce FX 5600 Ultra performs much like a GeForce4 Ti 4200 in situations where no anti-aliasing or anisotropic filtering is used. Enabling either or both of those features allow the 5600 Ultra to significantly outperform the GeForce4 Ti 4200, mostly thanks to the NV31's superior memory controller, compression and AA engines.
The GeForce FX 5200 Ultra performs slightly above the level of a GeForce4 MX 460 in situations where no AA or aniso is enabled
but once again, enabling those features causes the 5200 Ultra to perform more like a GeForce4 Ti 4200 than a GeForce4 MX. The reason behind this is obviously not because of any compression algorithms (as there is no color/Z compression in the NV34 GPU), but rather because of the AA and anisotropic filtering engines, as well as a vastly improved memory controller when compared to the GeForce4 MX (not to mention the higher clock speeds).
