The 6200 is a NV43 derivative, meaning it is built on the same 0.11-micron (110nm) process on which the 6600 is built. In fact, the two chips are virtually identical with the 6200 having only 4 active pixel pipelines on its die. There is one other architectural difference between the 6200 and the rest of the GeForce 6 family, and that is the lack of any color or z-compression support in the memory controller. Color and Z-compression are wonderful ways of reducing the memory bandwidth overhead of enabling technologies such as anti-aliasing. So, without support for that compression, we can expect the 6200 to take a bigger hit when turning on AA and anisotropic filtering. The benefit here is that the 6200 doesn't have the fill rate or the memory bandwidth to run most games at higher resolutions. Therefore, those who buy the 6200 won't be able to play at resolutions where the lack of color and z-compression would really matter with AA enabled. We'll investigate this a bit more in our performance tests.
