Meh.
We'll see how the next week develops. ATI may have wasted their time developing crossfire for the current generation. This all just does not make sense. I mean why go through all the trouble of coming up with Crossifre to counter SLI so long after SLI's release AND knowing that the G70 was ready. This has to be a "me too" markieting ploy to say that they have multi-gpu just so they say they have it, knowaddimean?
Regardless, the numbers aren't the silver bullet ATI has been hoping for by this early test, but can you call two weeks after the "product launch" early?. We'll see as more reviews come out. That reminds me, where are the reviews?
Edit: That sounded pretty down on ATI. Not my intent. Given they are beta drivers, beta hardware, but if Crossfire were to be available in July, this beta can't be far from the final product. Idunno. We'll see. I honestly hope it gets faster to prevent NVIDIA from resting on the SLI.

The only thing I find interesting is the SLI version "appears" to be scaling a bit better. But more or less they are the same with AFR.

With the recent release of crossfire, ATI is trying to prevent their enthusiast fans from switching to nVidia (G70).
If a (2 generations ago) two card crossfire solution is comparable with a G70 in FPS on current games, that might persuade the existing x8xx owners/fanboys to buy another $400-$500 x8xx crossfire card and motherboard to get G70 comparable FPS.
IMHO anyone who buys an x8xx crossfire card is a sucker.
The R520 may be an entirely different story and I hope it out performs the G70 in features and speed. I am not a fanboy. Competition is good for us consumers.

It no surprise, ATI are in a real BIG mess with alots of problems, Crossfire motherboards and videocards will start shipping in August, it over 1 year too late and overpriced with a X850 Crossfire Edition to sell for $549 each from August. Geforce 7800 GTX are much cheaper, all Nvidia's retail launch partners are already have Geforce 7800 series in stocks in advanced of 22nd June 6.01am that the time it will be available on sales when NDA will be lift. ATI will lose millions in revenues because they are lagging behind failed to catched up, soon they will be 2 years behind with Crossfire when Nvidia will launch SLi 2 soon.

That tells me you are not good at basic math. :nono:
From what we know already 7800 GTX is going to be between $549 to $600. Today Inquirer is saying that it is selling for $639.
In what way is $639 cheaper than $549. Things bias does to people. :eek:

Can you explain to me what nvidia is planning with SLI2? I've heard a bit about it, I'm not fully aware of what they are changing/adding though?
The main reason, I believe, Nvidia came with SLI was becuase it saved them a product refresh. That was a very smart move.. And while ATI was wasting time bringing out the x850, stumbling over their feet...Nvidia was killing them with SLI. Great strat...and it worked out perfectly for them.
The only thing I'm saying is, when I look solely at ATI's technology I see great potential, in crossfire..and the R520...they could have a real nice thing going. I agree they are in a bit of a mess right now, and are no doubt disorentated with all the R500/R520/Crossover buisiness...I'm sure that they will get their act together soon. I just hope by that time it isn't too late. Cause I'm very tempted to just get 2 7800gtx's..I already have an Asus AN8 Deluxe SLI board.
But I'm still waiting for ATI to show what they got before doing anything.

hmmm 2 video cards or 4 video cards...tough ?....and that fact that you can get the dualcore video cards and just run 2 video cards with 4 gpu on one board and still have 2 pciexpress video slots left....aegis?

You not quite get it, a Geforce 7800 GTX cost $357 to make (http://www.theinquirer.net/?article=23649), I bet it will be retail at $499 to $549 for 256Mb version and $649 for 512Mb version. A single 7800 GTX has same performance as dual X850 XT PE cards, a Crossfire X850 Edition card cost $549 and X850 XT PE slave card cost $500 (http://www.pricewatch.com/prc.aspx?i=37&a=165447) and the total cost will be $1049 in August then a few months after when R520 on sales, the X850 XT PE slave card price will fall by about $200. Geforce 7800 GTX will be still alot cheaper. :)

Thats the extent of what I've heard about it...and I dont really consider it much at all.
I need more info before I will comment further on it. For the time being...I see no reason for Nvidia to be really worried about increasing the bandwidth when ATI's crossfire seemingly has less already in certaint situations.
I think nvidia should mostly worry about card vs card performance between the G70/r520.
If Nvidia can lock that down...they will have another successful series.
And I do agree with you...that pricing for Crossfire cards is rediculous. I'm not sure if 7800GTx will be quite 2 x850xtpe cards...(dunno where you got that from) but the price/performance ratio will be much better with 1 7800gtx compared to 2 x850 cards.
Someone would be stupid to buy 2 x850xtpe cards at ~$1000 when a 7800GTx at ~$600 will give you pretty much the same performance with many more features.

Not to mention buying 2 of them and getting twice the performance in SLI for the same price almost

That's was 639 to have one installed in
a new PC.
We all know Everyone is going to jackup
the Nvidia price by 1 to 200 bucks for
the first month or 2. They always do.
I see nvidia with the 7800 and SLI2 being
a real winner into next year. :angel:

I think the biggest thing is nvidia has went back and tweaked
the board and made it more stable.
But if nvidia can bring it on out soon they will have
a Huge leap over ATI with SLI2 coming out even before
ATI can bring on there first Gen board. Plus with 7800 to boot.
Nvidia is looking good for the rest of 05 into 06 on sales for sure.
The biggest reason Crossfire will fail is that noone is going to buy an ATI mobo and they will also be hard to find.Nvidia has sold more than 1million SLI mobos and ATI's decition not to support them is plain stupid.Moreover launching Crossfire with X850 a month before nvidias next gen is another poor decition.
I disagree the Crossfire board seems excellent, without ATi's South bridge that is :D Anyway the crossfire boards are PASSIVE no noise and lower cooling needed also they are cheaper to make, and is a two chip soloution so as such yields should not be a problem. There is no switching boards or expensive digital switches. ATi are brining the X850 and X800 cards to crossfire as thats what everyone has at the moment not everyone wants the greatest and most expensive more so when you have buy both. Again as with SLi you buy one card now and buy an other down the road. Good thing is the cards don't have to use the exact same BIOS to work correctly and that to work. People have board two cards from the same manufature and still had problems *Cough* Leadtek, ASUS, MSI all come to mind. I was lucky my MSI cards worked without any problems but there was a hell of a lot people with the same cards that did have problems screen curuption missing textures etc.

I don't think that was ATi's decision not to support them... ;)
Why would ATi make boards for? nVidia doesn't they sell the chips not boards. ASUS, Leadtek, BFG and MSI etc sell the boards. ALso 1 million an't alot considering the lengh of time they have been selling.

Pulling these numbers from where ? :D 7800GTX will outperform two 512MB 6800 Ultras costing $1600. So ? The products you are comparing are previous generation versus new generation. The comparision is totally flawed.

I thought Crossfire was compatible with all motherboards even Nvidia Sli motherboards.

No, ATI has said that they will evaluate support for Nforce SLI in the future.Quite vaig isn't it!?

Yes but they didnt say that they wont support them, did they ? Wrong to assume that then.
Also I heard that ATI could lock their Catalyst drivers not to support SLi motherboard (if they decide not to support) and people will hack those drivers to make it possible. :D
Not untill they do support them outright will anything be clear.
Semantics

That, mi friend, is complete BS. It will be an achievement, if 7800GTX will Outperform 2x68GT's.
The only reasons why XFire will fail (right now) are,
1] The Master Card SH1T (ati certainly wont be able to supply master cards all over the world, its simply impossible)
2] investing in a x8xx now, isnt correct, that most of the people out there have quite clearly understood.
But i think, ati have already given up on x8xx series, they are more intrested in r520, xfire and r520's in xfire.
The
The reason they have the R4x0 as Xfire is due to most people have them cards right now. But i agree with the master card it will be hard at first till they get the compose engine yields higher.
