The Results - 133/100 MHz Bus Quake 3 Arena Results

To give you an idea of what type of performance gain you'll see from the various bus speeds, I've tested each chipset that was successful at 133 MHz bus with PC100 CAS2 and PC133 CAS2/3 in Quake 3 Arena in Normal mode.

Here you can see that the jump from PC100 to PC133 is a solid gain for most but not all cards. In the case of the TNT2 Ultra it appears that the system is so fast that it actually reaches the video card's fill-rate peak at this low resolution as the increased system performance barely helps the framerate. The step from CAS3 to CAS2 is minor but for the high performance enthusiasts, this still is an attractive gain.
