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 ... - Thomas -- ------------------------------------------------------------------------------- Das Reh springt hoch, e-mail: roell@sgcs.com das Reh springt weit, #include <sys/pizza.h> was soll es tun, es hat ja Zeit ...
