- Sorry, but this way of comparing things is quite rediculuts, if not
- even dumb (sorry folks , but I lack a better word of stating that somebody is
- not the brightest mind if he/she does things like that ;-)).

- The issue here is that you have to compare two things that appeared at the
- market at about the same time. For example 86C911 vs. WD90C31
- would make sence (ca 55k xstones vs. 45k xstones). Also 86C801/86C805
- vs. mach32 (Ultra Pro) gives some sence: 100k vs. 64k. Or if you want
- to stay in the domain S3, 801 vs 928. But what you do is comparing a
- chip that's ONE year old, and which in fact was one of the very first
- so called Windows accelerators. The 801/805/928 are simply the next
- generation, and hence much faster than the last generation. Other uneaqual
- comparisons wouldn't help you in comparing DRAM vs. VRAM at all.
-
- You are right if you compare the price/performance ratio of the 911 and
- a 801 based board today. But the 928 bases boards are just around the corner
- and will not cost much more than 801 based boards. That's the scenario where
- my comments apply. Then we have the same chips design as base and can compare
- a VRAM and a DRAM implementation with the same graphics engine ...
