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.
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.
