The Creative Labs GeForce 2 MX with DDR memory is slower than other GeForce MX's. How? Take a look:
Creative DDR MX is only clocked at lousy 143MHz DDR. That is approximately equivalent 286 MHZ SDR. However, the memory bus is only 64 bits. That gives a bandwidth of :
143 MHz * 2 (DDR) * 64 bits = 2.288 Gbytes/sec
166 MHz * 1 (SDR) * 128 bits = 2.656 Gbytes/sec
The other MXs are clocked at 166 MHz SDR, but have a 128 bit bus. Thus they have a higher bandwidth. At lower resolutions then, a DDR MX from Creative should be the same as a SDR MX since bandwidth is not an issue. At higher resolutions, the bandwidth will come into play. The Creative DDR MX will perform worse.
