Based on the feature set, the RADEON 8500 should be a faster card for Doom than the GeForce4 Ti, because it can do the seven texture accesses that I need in a single pass, while it takes two or three passes (depending on details) on the GeForce4 Ti.
However, in practice, the GeForce4 Ti consistently runs faster due to a highly efficient implementation since it is actually the primary research platform due to better drivers.
The GeForce4 MX is less suited for DOOM, due to the lower texture unit count and the lack of vertex shaders.
On a slow CPU with all features enabled, the GF3 will be faster than the GeForce4 MX, because it offloads some work. On systems with CPU power to burn, the GeForce4 MX may still be faster.
GeForce2 GTS family systems will be faster than the Radeon-7500 systems, again due to low level implementation details overshadowing the extra texture unit.
The slowest cards will be the 64-bit and SDR SDRAM GeForce and RADEON cards, which will really not be fast enough to play the game properly unless you run at 320x240 or so.
