170 MHz

150 MHz

The difference is within the margin of error. Looks like 3DMark2000 can't really take advantage of the higher bus speeds.

3DMark2001 however is known to love high bus speeds. How does the Ice 150 fair under this benchmark? Pretty well by the looks of it.

170 MHz

150 MHz

250+ point increase isn't too bad! Remember, the system with a 150 MHz bus speed does have a CPU speed advantage. Not much, but it is there.
