Well, color me purple, check this out.... QWET at 200 Mhz system clock, 800 MHz FSB..... (all the above runs were done at 333 Mhz or 1333 MHz FSB) EDIT: NOTE -- memory divider was not changed, this run is at DDR2-400 Mhz.... my bad.
Resolution: 1024×768
Score = 147 FPS
Score = 140 FPS
Score = 147 FPS
Average score = 144 FPS
Resolution: 1280×1024
Score = 144 FPS
Score = 141 FPS
Score = 139 FPS
Average score = 141 FPS
Resolution: 1920×1200 (HD WideScreen)
Score = 137 FPS
Score = 140 FPS
Score = 142 FPS
Average score = 139 FPS
Let's see what we get when we go to 1600 MHz FSB.
EDIT: OOOPS my bad... this was 200 MHz (800 MHz FSB), but I forgot to up the memory divider.... I am rerunning now at 200 Mhz FSB + DDR2-800 instead of DDR2-400. This may prove informative since I mentioned above that the GPU can go straight to system memory in one hop.
Output for DDR2-800 ...
Resolution: 1024×768
Score = 158 FPS
Score = 163 FPS
Score = 160 FPS
Average score = 160 FPS
Resolution: 1280×1024
Score = 157 FPS
Score = 157 FPS
Score = 160 FPS
Average score = 158 FPS
Resolution: 1920×1200 (HD WideScreen)
Score = 155 FPS
Score = 156 FPS
Score = 156 FPS
Average score = 155 FPS
So in this case a 40% decrease in FSB BW translates into a 7-10% hit in FPS.
