... do you always have to read a Z [buffer]? Nope, in some systems you can skirt this issue as well. Because of NDA's I can't tell you how Nvidia or 3Dfx or S3 or anybody actually gets more bandwidth out of a system, all I can say is that the simplistic calculations are utterly beside the point.
Oh btw Hardware-One is being humped like crazy, so it may be slow in loading.q3demo1 in 32-bit:
640x480 800x600 1024x768 1280x960 77.0 62.6 42.3 26.7
q3demo1 in 16-bit:
640x480 800x600 1024x768 1280x960 82.7 80.3 68.4 47.0
DDR memory is the very latest in graphics subsystem memory and offers power users increased performance at higher resolutions and deeper color depths. By utilizing both the front and back edges of the memory clock DDR memory achieves approximately double the bandwidth of conventional technologies such as SDRAM and SGRAM. This dramatic increase in memory bandwidth eliminates one of the major bottlenecks for high performance graphics.
