Meh, it gets tiling pretty quickly...
You were not missing much, i had this, the bro in law bought the 3dfx, i was the sap, the support for the 3dfx was amazing even at a time when you had to wait for a monthly magazine with a free floppy or cd to get access to game patches, lots of games got updates to support 3dfx, only a few got updates to support the powervr.......but i rectified that by grabbing a 3dfx 2. Ha
Hello, can you tell more about the graphics chipset for Dreamcast
The Dreamcast chipset was an NEC PowerVR chip basically.
PowerVR is a tile based chip instead of brute force. It would divide the screen in tiles and push all its power to finish each tile. That means that if a tile has just a sky, it finishes really fast and a tile that has transparency, it won't bog down the whole thing.
A 3dfx card was a brute force card, it would try to render everything at once, so on paper, 3dfx had more raw power than powervr, but it wasn't as efficient in doing stuff as powervr.
Back then, the 3dfx was indeed a faster card by alot, but... PowerVR is still alive in a lot of phones and the tiling rendering tech is being used one way or another in current desktop cards from nvidia and amd (But not exactly the same way as it was back then.)
Sega ultimately went with PowerVR because Sega were angry when 3DFX publically revealed their partnership due to becoming a publically traded company. That, and NEC are a Japanese company.
I'm not sure the Dreamcast would have helped 3DFX's chances one bit. 3DFX collapsed because they decided to make their own graphics cards, meaning all of their former board partners became competitors overnight. The onus on making Voodoo price competitive was down to 3DFX themselves rather than board partners. The fate of 3DFX is probably why Nvidia and AMD will never make their own cards en masse even though they probably could. Even Nvidia's Founder's Edition cards aren't made by Nvidia themselves.
Also 3dfx bought their fab in Mexico, which I'm guessing is at least a little more expensive to operate than a plant in, say, Taiwan.
