- You should see a decent amount of increase in any FP intesive application
- (like LW). The thing to remember here is that the 100MHz and the 66MHz are
- very similar. The 66 is a clock doubled 33Mhz chip, and the 100 is a clock
- *tripled* (not quadrupled like "DX4" would lead most to believe) 33MHz chip.
- What this means is that the chip actually "talks" to the rest of the computer
- at 33MHz on *both* the 66 and the 100. Inside the chip, however, calculations
- and computations are done at the clock tripled rate.
-
- Basically, it thinks at 100MHz and talks at 33MHz. So, LW should run
- significantly faster on a 100, but other applications may not see much of an
- increase at all.
-
- Any program that is "processor bus intensive" would not see much of the
- increase. A very typical example is VR. VR does fairly little calculating on
- each "set" of data, but it deals with massive amounts of these "sets".
- LightWave does massive amounts of calculating on relatively few "sets" of
- data, and is therefor not considered very bus intensive.
