NVIDIA's Last Minute Effort
On the virge of ATI's R420 GPU launch, NVIDIA brought out a new card called the GeForce 6850 Ultra. This new card is to be sold as an OEM overclocked part (ala the "Golden Sample" and other such beasts), and will be able to run at 450MHz+ core and 1.1GHz+ memory clcok speeds. It is very clear to us getting this board out here right now was a bit of a rush for NVIDIA, and it would seem that they didn't expect to see the kind of performance ATI's X800 series can deliver. We were unable to get drivers installed and running on our 6850 Ultra card until about two hours ago, but we will be following this article up with an update to the data as soon as we are able to benchmark the card. The 6850 Ultra looks exactly the same as the 6800 Ultra (it really is the same card with an overclock), so we'll forego the pictures.
