NVIDIA Single Card, Multi-GPU: GeForce 7950 GX2

Battlefield 2 Performance
At the lowest resolution with and without AA, both the highest end ATI card we tested (the X1900 XT) and the NVIDIA 7900 GTX lead the 7950 GX2 in performance. In most other (non CPU limited) cases, we will see the new NVIDIA flagship part come out on top, but this is one case where the added overhead of multi-GPU management gets in the way. Hopefully anyone who has one fo these cards will also own a display that does much higher resolutions than 1280x1024.
Again, at 1600x1200 without AA we see the 7950 GX2 running into a CPU limitation. When 4xAA gets enabled, we see the 7950 GX2 jump to the front of the class. In fact, enabling 4xAA only causes the 7950 GX2 to drop an average of 2.6 frames per second from the non-antialiased benchmark.
Running at our highest resolution, both with and without AA leaves the 7950 GX2 solidly in the performance lead under BF2. It isn't surprising that the closest competitor is the 7900 GT SLI setup, followed by the X1900 XT. At the maximum quality setting, the 7900 GTX falls a stunning 36% (or 19.1 average fps) behind the 7950 GX2. Not every game delivers results this impressive, but BF2 is certainly a good title to perform well under.

Hello all,Just want to inform everyone that the article is now as it was intended to be. As has been mentioned before, we had some server trouble this morning which distracted me from getting everything posted up quite correctly.
Here's a short list of things added since the article went live --
1) Idle and Load power and power commentary
2) Analysis on each benchmark page for each resolution
3) a corrected typo wrt power draw between the 7950 GX2 and X1900XT
Sorry for the oversight, but all should be in order now. Please let me know if anything is out of the ordinary.

Any chance to include an Oblivion page in the review?I'm thinking of buying one of these beasts, but I'd really like to see that first.
Thanks!

Based on the rest of the results, looks like it should be just ahead of a couple 7900GT's in SLI... so... figure 5-10% better performance than a pair of 7900GT's.Regs - Monday, June 5, 2006 - link
I play HL2 EP One at 1600x1200 4x/4x Max and it's perfectly playable with a over clocked 7800GT with a 2.4 GHz AMD. Though other games at that setting it's a slide show...so I really have no point. But hey, I posted!JarredWalton - Monday, June 5, 2006 - link
We show 64.1 FPS at that setting, so yes, the game is imminently playable at 16x12 4x/8x with anything 7800GT/X1800 level or higher.JarredWalton - Monday, June 5, 2006 - link
"eminently playable" as well. ;)DerekWilson - Monday, June 5, 2006 - link
lets have a hand for our editor folks :-)Fenixgoon - Monday, June 5, 2006 - link
Where's the ATI x1900 XT crossfire? that would definitely make a more complete benchmark (people buying 7900GT SLI will probably also look at x1900 or x1800 crossfire)JarredWalton - Monday, June 5, 2006 - link
Considering this is a $600 single PCIe slot (double-wide) solution, its fair to compare it to single GPUs. The 7900 GT SLI is thrown in for reference, and you can see how other multi-GPU solutions stack up in other articles. X1900 XT CF (and 7900 GTX SLI) will certainly be faster, but both will also cost at least 50% more. If nothing else, the PCIe switch is an interesting development.MacGuffin - Monday, June 5, 2006 - link
That point is valid. This is available from XFX for $599 at NewEgg as we speak (in stock). X1900XT Crossfire is atleast $400+$450=$850+. But still, I'm sure it would make for a nice shootout (7900GTX SLI, X1900XT CF and this lone warrior).Quick question: does the 7950GX2 require games to have SLI-profiles for it to utilize both GPUs?
