Black & White 2 Performance
Unlike BF2, we see the 7950 GX2 and 7900 GT SLI solutions neck and neck for the top performance spot under B&W2 at low resolutions with and without AA. As the resolution gets increase, we see the situation change slightly.
Even if we increase the resolution a little bit, it still appaers that the 7950 GX2 and 7900 GT are a little CPU limited. No reason to waste time here today, let's move on to the heavy impact test.
In this instance, we see a huge performance difference between the 7950 GX2 and its closest competitor (which is no longer the 7900 GT SLI). The X1900 XT drops in on second place thist time around and I don't even get so much as a nod.

Yes, SLI profiles are used for full utilization of the GX2 card. (AFAIK - Derek can correct me if I'm wrong.)DerekWilson - Monday, June 5, 2006 - link
SLI profiles are used if availalbe, but SLI profiles are never required to enable multi-GPU support on NVIDIA hardware.there are some advanced options for enabling multi-GPU or single-GPU rendering in the control panel -- even down to the AFR or SFR mode type (and SLIAA modes as a fallback if nothing else will work for you).
in short -- required: no, used: yes.

haven't read the article yet as I didn't see reference to Oblivion benchmarks, and lets be honest, that's the only game out these days that's worth benchmarking (in terms of actually giving the high end cards an actual workout).DigitalFreak - Monday, June 5, 2006 - link
It's amazing all the cool stuff you can do with PCI Express.Sniderhouse - Monday, June 5, 2006 - link
The Voodoo5 5500 had two GPUs on a single card which did true SLI, not to mention the Voodoo5 6000 which had four GPUs, but never really made it to market.

The x24 was also a dual pcb video card, thats what he meant. Not dual chip or whatever.timmiser - Monday, June 5, 2006 - link
Exactly what I was thinking!DerekWilson - Monday, June 5, 2006 - link
Perhaps I should have said successful products ... or products that were availble in any real quantity :-)photoguy99 - Monday, June 5, 2006 - link
From page 1, what limitations are being referred to?Ryan Smith - Monday, June 5, 2006 - link
DX9 itself has a good deal of overhead in some situations, something Microsoft is changing for DX10. We'll have more on that in our upcomming Vista article later this week.
