NVIDIA's co-founder Curtis Priem was a designer for IBM Professional Graphics Controller(PGC) and SUN GX graphics chip (1986-1993). NV1 was released sometime in ~1995.
NVIDIA was not the driving force for pre-1995 PC graphics. Also, Intel i860/i960 VLIW-RISC 3D chip was used in SGI machines.
In 1984, PGC has 640×480 with 256 colors and a refresh rate of 60 Hertz.
ATI Mach 8 was released sometime in 1991.
ATI Mach 32 was released sometime in 1992.
ATI Mach 64 was released sometime in 1994.
Can C= AGA compete against ATI Mach 32?
How much were those cards back then? I'm guessing a bit out of the typical consumer range...
