An Odd Question about the Voodoo2.

[ChrisRay]

Does anyone have information on the Voodoo1/Voodoo2 Pixel pipelines set up? I know the Banshee itself lost multitexturing capabilities but finding information on these cards is pretty hard.

I am seeing 100 Mpixel, So can I assume it was a 1x2 hardware?

Voodoo2 is is 1x2 indeed.. as in 1 chip x 2 chips, not pipes
But yeah, you could say the same as pipes I suppose?

Dont see it listed there under the boards.. hmm.. Unless I am missing it? (could be its late)

SST1 = Voodoo 1 (in Consumer form), SST96 = Voodoo 2.

The differences between SST1 and SSt2 were actually smaller than people expect since everyone rembers Voodoo2 as having SLI and multitexturing. The truth is, both SST1 and SST96 had capabilities of SLI and up to three texturing units per board. The guys were hawking this round lots of different places (arcade vendors, vis / sim etc) before memory prices crashed and the could put one out for the PC - however to do this they could only have one texture chip for Voodoo1.

Hmm, that chart misses off the Neon250, Pcx-2 and Pcx-1

One major difference between Voodoo 1 and 2 was in the triangle setup engine.

Voodoo 1 had to do CPU work per triangle (interpolate calculation), Voodoo 2 had a hardware setup engine with no work needed per triangle. Hence much higher geometry throughput.

He has programming specs for most of the chips. I kept my old V1 and V3 boards for programming fun some time in the future. And my old S3 Virge too since years ago when I emailed S3 they were nice enough to send me programming specs. One day I'll make it draw a jurassic era triangle.
