I agree with you, but when nvidia talks about the nv30 they say 400 million, 1000 engineers (including TSMC engineers), 48GB/s memory bandwidth (compressed)...
Nope.
They say $400M for the NV3x product family.
And $100M specifically for the NV30.
So it's $100M, not $400M!
Who brought us fast-Z clears, hierarchical-Z, lightning fast AF, AA, 128-bit color, hardware gama correction (vs nv30 pixel shaders), best image quality and all the ALL in wonder innovations? ATI, ATI, ATI, ATI
Psst, small mistake. All the things you said were created by ATI, beside 128-bit color. ATI is still using *96-bit color* in the PS, only nVidia is using 128-bit.
I have heard that nvidia was responsible for pixel shaders, but I recall John Carmack had complained because they were implemented poorly. Nvidia was also first with the crossbar memory controller on a video card (although they have been on other devices for a long time).
DX8.0 Pixel Shaders *and* Vertex Shaders is proprietary technology invented by nVidia.
The DX8 PS implementation was very basic however. IIRC, Carmack's complain was that it wasn't sufficently flexible ( -> NV30 PS which give ridiculously high limits )
nVidia thus implemented the following technologies before ATI ( that doesn't mean they invented them: many were available for super expensive workstations way before )
T&L, NSR ( nVidia Shading Rasterizer, that's from the GF2 ) , VS/PS, 128-bit color, multisampling, crossbar memory architecture, ...
