Recently I've heard that the V6/V8/V10/V12 uses a modified
GeForce2/Quadro2 chip from nVidia.
I had thought that only the V3/VR3/V5/V7/VR7 cards for the x86 machines
used nVidia graphics and that the Octane2 graphics were designed by SGI.
Can anyone confirm or deny any of this?
Octane2/Fuel/Tezro VPro "Odyssey" graphics were designed by SGI.
x86 PC VPro GeForce/Quadro graphics (V3/VR3/V5, etc) were designed by
Depending on who tells the story, GeForce and Odyssey were born out of
the same original project at SGI. The similarities end there, however.
GeForce was designed by NVIDIA for the game-playing, DVD-watching home
user and has a fillrate emphasis. Odyssey was designed by SGI for cad,
modeling, vis-sim, and video production users. V12 has pretty serious
real-world geometry power, even by current standards. 48 bit color and
several other features make it a powerful, balanced gfx pipe for video
work (Piranha, various Discreet apps, MuleHD).
About the only thing GeForce and Odyssey have in common is the concept
of a single-chip "GPU". The design/architecture, interface, and
feature sets are very different.
