The ONLY modern graphics card that makes this true is the GeForce2 MX. The reason is that if it uses SDRAM, the memory path is 128 bits; if it uses DDR-SDRAM, the memory path is only 64 bits. Why it is setup this way, I don't know, but it makes it so that there is no memory bandwidth difference between SDRAM models and DDR-SDRAM models.
