wow.. thats not too bad! For a last gen card the numbers are pretty decent :)

Given the 7800GTX SLI a bit of scare :)

wow really impressive
its sad see how slow 6800U SLI is

The GA-K8AMVP Pro is based on the ATI's latest RD480 chipset paired with a ULi south bridge and features CrossFire support. We'll be taking a closer look at this board as well, as Gigabyte tells us that it can even support 2x 3D1 cards. The board looks very similar to Gigabyte's NF4 SLI boards, including the selector paddle for configuring the PCI Express ports. Flipped to single GPU, the first PCI Express slot gets 16 lanes, and flipped to multi GPU mode will run each slot at x8.
Does that mean what i think it does...quad GPU's ?

How so the games that ATi has a lead in is where xfire does better, and where its behind its behind with xfire.

Well if u think they just used the not pe for crossfire i think they would take a lead in anything
the only game were 6800usli is faster is d3
and in splinter cell crossfire is 25% faster than sli 6800U
hope that with 7800 nvidia will not forget old 6800 users
the X850XT is a faster card than the 6800U (well at least that's my impression), so no big surprise for me
Still, who will crossfire SM2 cards these days? Spending that much money but not getting the eyecandy?
It's the R520 numbers that will be important.
But it looks like ATI managed to come pretty close to SLI in performance and features.

The bigger problem is that the 7800GTX continues to drop in price. How much will the Crossfire X850 cost? How much for the mobo? How about power supplies? Single 7800GTX starts to look pretty appealing.
So yeah, nice scores for the games you would expect a dual ATI solution to do well in. It isn't shocking, meh. What it is is far too late...

With the Splinter Cell benchmark all the tests were done in SM 1.1 instead of SM 3.0(for nVidia)

Yes I agree this seems to little, to late. Hard to see how it will sell well. They need R520 out and soon.

Tell me this, how many games today actually use SM3 for anything important? According to this thread on the games boards, none, really. (http://www.nvnews.net/vbulletin/showthread.php?t=53551)
Maybe it's more correct to just say "advanced features" instead of SM 3.0 and there are several that use things such as HDR that aren't supported on ATI cards.

It's late in the sense that it took ATi time to come up with an SLI competitor but these things aren't created overnight. The fact that it puts out impressive enough numbers to give a 7800 GTX SLI setup a run for its money is VERY impressive - esp. when you consider how much a 7800 GTX SLI setup costs. If ATi drops the X850 prices to the $350 mark they will be sitting in a very good position. Anyhow this preview was more to show Crossfire's potential rather than advocating X850 Xfire. It's obvious Xfire will premiere when R520 shows up. However judging by the numbers the X850 is putting out, if I were nVidia I'd be scared.

I'm not entirely sure I trust those results for Splinter Cell: Chaos Theory. I want to be very specific by what I mean. In my experience SC: Theory scales about 75% with AA/AF. And the benchmark results for SLI here dont. Also a 6800GT SLI is always faster than a 7800GTX in Splinter Cell: Chaos Theory @ 1600x1200 with 4xAA/16xAF. So that makes me even more curious about whats going on with the representation of SLI scaling. Splinter Cell is actually one of the few games where I have seen nearly double the performance with SLI.
Also keep in mind those benches arent performed on identical systems. and the results were used from an earlier review. You guys really should wait for benchmarks to be performed on identical systems before jumping to conclusions about SLI scaling. Higher resolutions will now start needing to be compared as a 7800GTX SLI setup is CPU limited in most games @ 1600x1200 with 4xAA/16xAF.

Ideed it is far too late when it launch in Sept, Crossfire X850 cost $549, it is power hungry, it require around 600W PSU while 7800GTX SLI need just 500W PSU.

So why will ATi release this? Just to follow nVidia's lead in dual video card products?

Well I wish I know why, it made no sense for them to release X850 Crossfire in Sept, it will be sense if it were released last year. ATI made big mistake to make X850 Crossfire, it will not have the same success as 6800 GT/Ultra SLI did, accorded to many surveys in many forums that as much as 75% said it not worth buy it this year, they are better off buy R520 Crossfire this year.

Not sure if i understand this but if you have a Crossfire mobo wouldn't you be able to use either 2 x X850's or 2 x R520's or doesn't it work like SLI where you can put 2x6600, 2x6800, 2x7800 cards in the same mobo :confused:
Impressive performance ! .. if ATi just foucsed on the Crossfire tech & delayed the R520 developing further i believe they would have given the 7800GTX/SLI a run for its money or at least keep up with the performance race.
seeing these numbers makes you wonder what 2xR520 will deliver in terms of performance even if it ended to be a highly overclocked 16 piper!!

Yes you need Crossfire motherboard, a Crossfire X850 (Master) card and a regular X850 (Slave) card to work but 2 regular cards wont work like 2x7800 cards in SLI, it need Crossfire card to get it work.

No chance, it far too late for that in Sept when it launch for $549, it couldnt outrun 7800GTX at $450.

Yeah i know . i was talking about the case if they launched it earlier than the GTX , but getting busy with the R520 & the X-Fire at same time is what screwed them IMO.

What i was trying to say is is there a different mobo required X850's and the R520 X850 Crossfire, R520 Crossfire

Nope i dont think so. both geners should work.
