I think the Matrox Millennium had acceleration for Gouraud shading and maybe z-buffering. Those were
the 2D cards to have, back in their day. Maybe Number Nine's Imagine 128 was faster, but I could never sort out the driver problems with the lone example I got to play with.
IInuyasha74 :
I left Kyro and all PowerVR based graphics solutions out, because PowerVR is not a fallen GPU manufacturer. Technically, a company could still use PowerVR graphics on a GPU add-on card or as an integrated graphics solution.
That's not a meaningful difference from your position on Matrox. If you're going to cover them in a separate article, fine. But, I think it makes sense to consider
all companies that have exited the PC mainstream GPU race, whatever their reason or present circumstances.
Please do a round 2 of this topic. I'd have liked to see coverage of:
3D Labs,
PowerVR,
Number Nine,
Trident, and
Cirrus Logic. That's not even all of them, but the first two certainly seemed like players. Thanks.
