NVIDIA GeForce 6800 Ultra: The Next Step Forward

The Card and The Test

This is our NVIDIA GeForce 6800 Ultra engineering sample. No, it's not one slot, yes, it has 2 molex connectors, and generally its actually not very loud.

The 16x1 GeForce 6800 Ultra will be clocked at 400/550 (core/mem) and priced at $499, while its 12x1 little brother the GeForce 6800 non-ultra will be priced at $299 (clock speeds to be determined).




Here's a quick rundown of the key features:

. Vertex Shaders
° Support for Microsoft DirectX 9.0 Vertex Shader 3.0
° Displacement mapping
° Vertex frequency stream divider
° 65000+ instruction length programs
. Pixel Shaders
° Support for DirectX 9.0 Pixel Shader 3.0
° Full pixel branching support
° Support for Multiple Render Target (MRTs)
° 65000+ instruction length programs
. Next-Generation Texture Engine
° Up to 16 textures per rendering pass
° Support for 16-bit floating point format and 32-bit floating point format
° Support for non-power of two textures
° Support for sRGB texture format forgamma textures
° DirectX and S3TC texture compression
. Full 128-bit floating point precision through the entire rendering pipeline (64-bit max precision to framebuffer and display)

The chip is 222 Million transistors fabbed on a .13 micron process. Currently a 480W power supply and 2 free completely independent connections to the PSU are required. 8x Rotated grid multisample antialiasing, and 16x (128tap) anisotropic filtering are available.

Our test system:

AMD Athlon 64 3400+
