NVIDIA GeForce 6800 128MB DDR (325/700 MHz)
This GPU is presented by Palit GeForce 6800 card.
- NVIDIA GeForce 6800 Ultra (12 pixel and 5 vertex pipelines), 325 MHz clock;
- 128MB DDR SGRAM in Hynix BGA chips; 350 (700) MHz max. clock rate.
- 256-bit bus;
- Peak fill rate in the multitexturing mode without optimizations is 3900 megapixels/sec and 3900 megatexels/sec.
By the end of the month the product costs $220-250, supports DirectX 9.0c (shaders 3.0).
This product, initially meant for the $300 niche, is getting cheaper now. It supports all innovations, including shaders 3.0. 2.8ns fetch indicates the actual 350 (700) MHz clock. AGP x4/x8.
This is a rather popular card with considerable GPU power and moderate price. Pity, but you might stumble upon 6800LE cards with 8 pixel and 4 vertex pipelines that are named the same. Or 12-pipeline 6800 cards with 4 of 5 vertex shaders. Therefore be careful. The new version of RivaTuner (available at www.guru3d.com) not only shows you the exact number of pipelines, but can manage them if not blocked in hardware.
RivaTuner utility will allow you to enable all 16 pixel and 6 vertex pipelines of NV40 bypassing the hardware lock. But this will be like a lottery, as only your experience will tell if they are operable or not.
