Notes
GeForce 6800 Ultra is the world’s first DX9.0c graphics card. Note, we said DX9.0c and not DX9.1, which was the designation incorrectly used to denote the addition of 3.0 pixel and vertex shaders into DX9. Another highlight in GeForce 6800 Ultra that will probably grab your attention is the chip’s transistor count: over 220 million! We were given a figure of 222 million at NVIDIA’s Editor’s Day. Basically, this is one big chip.
GeForce FX 6800 is also NVIDIA’s first native PCI Express graphics solution. Follow-up GeForce 6 series parts will also support PCI Express natively. NVIDIA has also integrated a video processor on the graphics core, circumventing the need for an external chip.
Lets take a closer look at a few of the more important features found in GeForce 6800 Ultra, starting with the new 3.0 pixel and vertex shaders.
