3DMark2001SE Car Chase
for the sake of saving bandwidth, we will be skipping most of the benchmarks that don't show any effects and concentrate on those that do and "Car Chase" is one of them
Car Chase, Low Detail
A meager 3% performance increase, courtesy of the higher memory bus frequency is almost negligible. The additional 8% performance increase (10.7 % spread), however, are significant enough to warrant a "Call for Action".
Car Chase, High Detail
With increasing resolution, raw memory bandwidth, especially for AGP texturing becomes more important. Therefore, the gain achieved by increasing the memory bus will yield higher gains (4 %) while the overall gain at 166/166 compared to the 133/133 setting remains at 10%. In other words, we see a relatively higher gain for the increased memory bandwidty at the high detail benchmark.
Lobby, Low Detail
A 4.6% booster from the higher memory bandwidth is very respectable but nothing to the additional 7.8% resulting from the 166 MHz FSB for a total of 12.2 % performance increase.
Lobby, High Detail
At higher LOD, it gets even better, 5.5% boost from the higher memory bandwidth, plus 8.4% resulting from the 166 MHz FSB for a 13.9% performance increase total.
Overall, these are whopping numbers that won't necessarily show up in complex benchmarks, especially, if other factors like the graphics adapter are the limiting system bottlenecks. One thing to keep in mind here is that benchmark results do not scale in a linear fashion with CPU frequency, that is, in order to get a 15% performance increase, one usually has to raise the total clock speed by at least 20%. That translates to no less than a 2.0 GHz processor delivering the raw power of a 2.4 GHz processor. Of course, this would have to result in another iteration of QuantiSpeed rating, maybe we would need another word then, like ........, well, suggestions are welcome as always.
