ATI's Multi-GPU Solution: CrossFire

Pricing and Availability
What ATI has here at Computex is a very early sample of what CrossFire can do. Much like NVIDIA has had, ATI will encounter growing pains of their own with CrossFire. Most motherboard manufacturers are telling us to expect CrossFire motherboards by the end of July at the earliest, but more realistically, we can expect retail availability sometime in August.The price point will be competitive with nForce4 Ultra (not SLI) motherboards, thanks to more aggressive chipset pricing on behalf of ATI. Also note that not all manufacturers will be producing both AMD and Intel CrossFire solutions. For example, MSI is producing an AMD CrossFire motherboard, while ASUS is currently only producing an Intel CrossFire solution. The problem is that most CrossFire manufacturers are also nForce4 SLI manufacturers and they have to be careful not to confuse their customers by offering two products that compete with one another. Choice is a good thing, but from a sales standpoint, it can sometimes be a difficult pill to swallow.
Despite the strong showing at Computex, most motherboard manufacturers have stated that they don't expect ATI's CrossFire chipsets to really make a dent in this year's shipments. ATI's high-end chipset market share will still remain very low in comparison to NVIDIA, but the long term outlooks are definitely positive. Much like they have done in the graphics industry, ATI will provide good balance to NVIDIA in the chipset business now that NVIDIA is king of the high-end AMD market.
The pricing of CrossFire X800 and X850 cards is listed in the following chart along with the existing products that each CrossFire part supports.
On the high end, we are definitely looking at an expensive upgrade. Those who want the ultimate in performance can be expected to shell out the cash. The X800 versions CrossFire are a little more compelling in terms of affordability.
It will be interesting to see how these CrossFire parts move in price as they are very targeted in application as opposed to NVIDIA's parts, which are marketed as standalone graphics cards that could be used in SLI.

Looks interesting to me, at least so far. I'll agree that we still have to see how things turn out.Eug - Tuesday, May 31, 2005 - link
Crossfire? Meh. About 0.1% of the population will buy dual GPU setups. Crossfire is essentially just a marketecture exercise.The really interesting part is the H.264 acceleration, which will have much, much more impact for the general computing world than Crossfire.

Interesting... They gave AT stock photos of a Intel based motherboard, but the benchmarking was done on an AMD rig. Anyone know if the chipset(s) support Athlon X2 and/or Pentium D?To the person that mentioned that Doom3 is not a good benchmark for ATi: My guess is that Doom3 is probably a good benchmark to use for this purpose. ATi is most assuredly GPU bound in Doom3, so any increase in GPU power will yield a positive result. Whereas in HL2 where ATi has really strong single performance, I would imgaine that the Crossfire rig is CPU lmited, so there is not as drastic of an increase.
Either way, Crossfire looks to be pretty interesting. Can't wait to see some in depth benches and some screenies of the super AA modes.
A request to AT: how about some benches in standard and widescreen resolutions. I know that SLI had compatibility issues with widescreen in the past, and it would be nice to know if those are still around and/or if Crossfire also suffers from this.
Nice article, especially with the limitation of not being able to run a full suite of benchmarks.

So what about the fact the new mode does not work in OpenGL? I happened to love playing with directX api but knowing that half the engines will not be able to use the new filtering? I like the idea of the new chip they are putting on the board, I'm disguested most of the ATI stuff is marketing not hardware I have to develope for the hardware in peoples machines and the baises that people have toward tech and i'm getting sick of finding a new way of doing something not being able to use it because it only works on nvidia and ati bashes till they sorta get it working then they claim it's the best thing since sliced bread. Lets try and force nvidia and ati marking people to focus on what is there not what there side has.DerekWilson - Tuesday, May 31, 2005 - link
I suppose we should add a disclaimer to the statement about Super AA working with everything ...From what we *hear* from ATI, all games will work with CrossFire. This means that all games will work with at least one of the performance or quality modes. Even if a game doesn't work under AFR, split, or supertiling, it should work with Super AA ...
But we will have to test compatibility for ourselves.

I can't see why they can't just use one PCIe card with a extra socket. Wheny ou ened to upgrade for more power then you buy just the chip and put the extra GPU chip in the socket to make a dual graphics card.SLI is a waste of time in that it's a direction in motherboard layout that isn't going to last, it's a dead end road for the future. So rather than was all the time developing cards that work in tandom, make the card to work with more GPU chip ont he same daughter board.

"all games will be accelerated under any Super AA mode"I hope Anandtech isn't pulling my leg here. I'd love to see Halo PC or Splinter Cell using AA. Currently no form of multisampling allows AA in these games. There are probably more games out there that have the same multisampling limitation, but these are the two I know of.

And should I had that investors seems to feel like ATI is taking its place back. NVDIA stocks already dropped 59 cents witht the announcement of ATI crossfire and R520 playback display...#37: totally agree, it is going to be a nice fight! If R520 is overall better than the G70, NVDIA will have to worry and counter it as fast as they can (which is going to be great for us).

I agree with #35. It is a little early to know which solution will be considered the best, even if it seems that ATI is bringing sone very interesting features along with their Crossfire. Not everybody care about playing Doom3 at 110 fps. I rather play at 80fps and have all the eye candies, and even more, since they are going to propose heavier FSAA.Since SLI and Crossfire will probably come to be close, it is going to see which one of the r520 and g70 will be the fastest with the most interesting features. But if ATI did as good with the R520 as they seem to have done with the Crossfire, they could take back the crown.
NVIDIA seems in hurry to put the G70 on the shelves, which seems kind of suspect, since there is are no real reasons to do so. They acually do have the most popular cards and the fastest configuration with SLI.
Did they heard about ATI R520 specs and fear to be at a disadvantage? Do they need two G70 to beat it?
Wait and See
#36 2PCI-E 8X -> that is exactly what SLI is right now with NVDIA.
Compositing Engine chip -> Do you remember the discussion about the PCI-E bridge implemented on GeForce 6 cards? Experience has shown no performance drop. Instead, in ATI's "SLI" solution, it seems even better since it is not part of the die -> less heat... It is not new to them, since there are using it in professionnals products

I think the next chipset king will be the one producing the best next-gen graphics cards. if NV70 is better performing than r520 then I wouldn't think that people are going to care about going ATI in the mobo department, but if r520>nv70, then nvidia may start losing the chipset market.this will be real interesting to watch, the first chipset war determined by graphics cards :P
