Crossfire beats SLI in Doom 3?!

well the x850xt is a bit better than the 6800ultra, so it kinds works out, but there are hardly any big differences in the technologies.

its standard, surprisingly, yet it shows off no feautres the setups can do since its so easy at that. they should set 12 x 10 as standard and 16 by 12 as higher, then you get the performance hits.

well, it looks like they only had a 17-19" LCD to bench with, thus were limmited to 1280x1024.
Looks like LCD manufacturers are going to have to get cranking on the 24" 1920x1200 screens 😉
promising, but it is too bad we didn't have the crossfire option 6 months ago - competition for SLI and demand for more than one high end card very well could have driven prices down all around. Ultra and XT prices might have remained high due to low yeilds, but dual XL and GT setups could have been more of a resonable high end option (albeit not super elite highend)

Is it just me, or do those framerates seem a little low?
The ones for the 12x10 with 4x8x seem about what Anand and other sites were getting for 16x12 with 4x8x.
Yep definitely something strange there. Comparing to AT's findings on the X850 launch, those numbers are way off, Text. Figuring in driver advancements made between now and then and those numbers seem even less reasonable (the ones from the OP's link).

Those framerates make no sense at all if they were using the standard Doom3 demo:

I'm getting 67fps at 16X12 4X8X on 6800GT SLI, they're getting 50fps at 12X10 4X8X? Has to be they had the vsynch on, used a different demo, or have downclocked their FX CPU. It makes no sense.

Here is the same test in an English article. Yes, they used a different test then the standard D3 benchmark.

Since Nvidia have far better OpenGL support i would take them results with a pinch of salt, and its not normally Euro that gets stuff b4 USA, i see it as asia gets 1st, they can preorder amd64 dual core cpu's now and i get stuff from Australia well b4 i can get anywhere else, im in UK btw.

Okey, North America.
I wouldn't be surprise if ATi Crossfire had an edge over SLi. Nvidia pushed the technology out first. ATi had lots of time to groom and improve it. I can only assume Nvidia will try to improve theirs as well. Either way one can only expect a tougher decision on which GPU manufacture to choose from.
lol.. and the fanboys have something to grasp at....
seriously.. regardless of which is faster, at 1024 there should be little difference between running aa/af and not; the bottleneck at this point is the cpu, not gpu -- at that res, aa/af or not, it's not much stress on a video cards of this caliber (let alone 2 of them). take a look at the dozens of bencmarks available on the internet, and you'll see there is almost no difference at that resolution when running aa/af...
it's certainly possible that ati may have somehow gained a small edge (tho even if these benches are accurate, it's still more parity than anything else; xfire loses by the same amount at 12x10) an edge, but these paricular benchmarks are highly suspicious at best.

It'd be funny if 6800U SLI cards beat x850 Crossfire in Half life 2...lol....

Usually the X850XTs can be found for about $450 (the PEs are usually about $550). Figure in the extra cost of the X850 Crossfire card (is what $550) so they're really about even in price ($1000 total).
