Looking over the net today I came across a few "news" posts on the Inquirer :o. Supposed "final details" and a "marketing slide presentation" for the HD38xx series, and a possible dual gpu graphics card named "3870x2" that's rumored to be coming soon. Anyway, here's the links

3870X2

3800 Presentation
 
going by that 3dmark06 the 3870 is only abit faster than the 2900xt. and the 3850 is far slower then the 2900xt... :eek:

Don't think your meant to hotlink Gareth.

So if that is a legit slide, basically it is just a die shrink with a few added (non-performance) related features. It's great that they have fixed all the issues, but really would have been good if they had raised the bar with a proper performance increase. As I see it the 3870 @ 775 is the ONLY reason it is ahead in that benchmark. The die shrink doesn't seem to bring any extra performance.

As I mentioned before I think this is really about reaping the development costs back from the R600 R&D, it is not about bringing a performance product to market.

The only hope really is that they learned lessons with the R600 and the R700 will be a massive improvement and worthy competitor of the NV 9 series when it is released.

Interesting about the x2 though (although picture looking fake), especially given that the crossfire performance is generally better than SLI performance (and more compatible from what I've read).

I am a bit skeptical about the picture too, it looks a bit like a photoshoped 8800 Ultra, Would be nice if it was real though, Also, with the 3800s, I think ATi are aiming at people going crossfire with them with the way they are pricing them. If the 3850s are a similar speed to a 2900XT then I can pretty much say I would buy two of them.
 
I wouldn't call it far, looks about 10% or so and I'd imagine they'd be able to overclock a bit at least to 2900XT speeds considering the original specs for the 3850s.
 
Gareth > I think so. Not heard the term "hotlink" until I came on ocuk though. Or you can just post the link :) I may be wrong btw, but I'm assuming an img link to another website is referred to as hotlinking (you'd think I'd know being a software developer lol).

Wonder how many full bus width pci-e 2.0 boards there are likely to be though? I wonder if there will be any 4 slot pci-e 2 boards, as Oct crossfire (4x 3870x2 boards) would be a laugh and a half, although I'm pretty sure you'd need a dual quad motherboard for that heavily overclocked!

hopefully in stock around november 19th.

It seems to be cheaper than 8800GT, quieter than the 8800GT, it requires less than 50% of power than the 2900, DirectX 10.1 (yeah, it is useless, whatever). It supports Full bitstream VC1 decoding, it is crossfireable and it blows the heat out of the case.
This card shoud be interesting for everyone but performance chart whores.

Depending on the price i might get one for my new system and later i will decide if i want to go crossfire or get a 9800GTX instead.

Oooo... I wonder if 8x cross-fire is even driver possible?

That board looks pretty nice :D That's not PCI-E 2 though is it?

EDIT: Dummy I am "quad PCIe 2.0 x16 VGA slots" lol.

Matthew
 
How do you know? Have you seen reference to this? To be honest, I envisaged a year ago about my ultimate system being 4 cards, 2 dual quad :) To have 8 cards would be a complete tickle, and probably completely hog the pci-e bandwidth lol.

in the future it will be possible for 4x dual cards to be crossfired

as long as they are running single slot coolers on the dual-die cards...... not likely.

the only 4x setup i've seen is with single slot coolers.

I have yet to see a mobo that has 4x PCI-E each 1 slot apart. Most 790FX are side-by-side with no gap, or with big gaps and only 3 PCI-E
 
gutting, the link for the 4x motherboard gareth gave me, the last slot is to close :( Such a shame. Maybe you can get a slot extender to move is sideways? lol

Even without it... 6x times cross-fire then?

Matthew
 
everybody knows new things get thiner and smaller as time pasts. in the future maybe they will start doing the high end cards as single slots.

as for drivers im sure they would do something to them to get 8x crossfire working

... That cooler looks crap. Had to be said, the 'sticker' on it looks stretched and distorted.

As for the 3850 not performing up to the 2900 XT, well to be honest that's not all that unpredictable, being it has 320 scalar shaders, and is clocked lower, and has a smaller memory bus. Really just is a die shrink. I think people forget the G92 did have a few genuine changes apart from the extra shaders, such as the increased texturing units, higher texture compression ratio and so on.
