NVIDIA's Last Minute Effort
On the verge 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 clock 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.
The other part NVIDIA is launching today is their $399 price point card, the GeForce 6800 GT. This card won't be shipping for a while (mid June), and NVIDIA cites the fact that they didn't want to announce the card too far ahead of availability as the reason for the timing of this announcement.
The 6800 GT is a 16x1 architecture card that runs at 350MHz core and 1GHz memory clocks. As we can see from the beautiful picture, NVIDIA is bringing out a single slot card with one molex power connector based on NV40. Even if its not the fastest thing we'll see today, it is still good news. We will definitely be trying our hand at a little overclocking in the future. Power requirements are much less than the 6800 Ultra part, with something like a 300W PSU being perfectly fine to run this card.
Along with this new card release, NVIDIA have pushed out new beta drivers (61.11), of which we are still evaluating the image quality. We haven't seen any filtering differences, but we currently exploring some shader based image quality tests.
The key factor in the ongoing battle is DirectX 9 performance. We will be taking the hardest look at games that exploit PS 2.0, but that's not all people play (and there aren't very many on the market yet), we have included some past favorites as well.
Our test system is:
FIC K8T800 Motherboard
AMD Athlon 64 3400+
1GB OCZ PC3400 RAM
Segate 120GB PATA HDD
510W PC Power & Cooling PSU
The drivers we used in testing are:
NVIDIA Beta ForceWare 60.72
NVIDIA Beta ForceWare 61.11
ATI CATALYST BETA (version unknown)
ATI CATALYST 4.4
We didn't observe any performance difference when moving to the Beta CATAYLST from 4.4 on 9800 XT, so we chose to forgo retesting everything on the new drivers. Also, the 61.11 driver does show a slight increase in performance on NVIDIA cards, so we retested previously benchmarked hardware with the 61.11 drivers. Old numbers will be left in the benchmarks for completeness sake.
As mentioned earlier, we will be updating our tests later today with number collected from the GeForce 6850 Ultra (and we'll throw in a few other surprises as well).
