no es ningúna "riva tnt", era una tarjeta bastante anterior, es más, esa tarjeta fue vendida por nVIDIA, y un montador (creo que fue diamond multimedia, en la epoca), la vendio como la primera aceleradora 3D del mercado (no hacia filtrados creo, y era inferior a una Voodoo1 o a la Rendition Vertite (ambas superiores claramente a N64). Esta tarjeta, se entregaba directamente con dos juegos de Sega (un Virtua Fighter, y no recuerdo cual era el otro) que SOLO funcionaban con esta tarjeta, y que para la época era la releche... supongo que esta será la tarjeta que comenta el de sega... (supongo) y que fue anterior a las Riva ZX/ Riva TNT

estas hablando de la Edge 3D, el chip era el nV1 y el montador era Sigma Designs.
Pero creo que no se trata de lo mismo, la edge 3D es de finales del 95 si no recuerdo mal, y este proyecto, si los datos son correctos, es bastante posterior.
saludos.

Al parecer este proyecto es de antes que llegara la Saturn a occidente, por lo que fue en la primera mitad del 95

"A little known fact is that Sega of America had specified not just a 3DFX
but a Motorola 603e (both American designed chips) for their preliminary
spec of the next-generation console, versus Sega Japan's spec of
Japanese-only hardware. (Note that more powerful variations of the new
design would also be used in next-gen Sega Arcade hardware.)
Sega Japan, which controls all of Sega, immediately rejected the Motorola
CPU in favor for an unavailable, untested, and unproven Hitachi processor
design. Sega's primary reason for rejecting the much more powerful and
well-proven Motorola PPC chip was primarlily political; they wanted a full
license to be made in Japanese fab under Sega's control, something I doubt Motorola would grant.
So both the Sega America (specifying 3DFX for graphics processor) and the Sega Japan designs
(specifying a yet unchosen Japanese chip for a graphics processor) were in competition
for the next console design, and Sega America was forced to change their specification for this unproven
and as-yet-unavailable new Hitachi processor as well.
Note that there are other reasons they'd want to go with a proprietary
processor; they didn't want to lose their tight control over developer
releases either; if the 603e and 3DFX combo was used, then it would be a
fairly simple matter to emulate the nextgen console on a PPC equipped with a 3DFX Voodoo card...
it would also open the door for developers to easily port the next-gen Sega console games to a powermac equipped with a 3DFX card;
and if there's one thing Japanese corporations will not tolerate, it's an open specification and the intense competition that comes with it. They *want* the system to stay proprietary and closed;
that's how they do business as a rule (name any Japanese computer system that follows an open spec;
even their laptops use proprietary RAM modules, CDROM modules, docking stations....). If someone wanted to clone the console, you can bet they'd have a very difficult time getting the processor chips from Hitachi.
So it comes as no surprise whatsoever that Sega Japan would overrule Sega America's design
and go with a Japanese graphics
processor as well. Since the only Japanese processor that currently
approachs the 3DFX's power was the NEC chip (which of course is a major player in corporate
Japan), it seemed *invitable* that they would go with this. Indeed I had been quite surprised when I first heard that they were considering the 3DFX at all.
"When Sega and 3Dfx signed that deal, Sega had at least two other
chipsets under development, and that there was no guarentee that
Sega would choose 3Dfx's chipset(In fact, the other two, PowerVR
Highlander and Real3D, were more favored). It was simply a contest of
who would provide Sega with most bang for its buck, and Highlander
won that contest, fair and square. I doubt Sega would not have
included an exit clause in the contracts it signed with all three
parties. At least I don't see Lockheed threatening to sue Sega, even
though their chipset was the fastest(and most expensive) of three."
