You can read about it here...

I was hoping for two RV670s on the same package.

Do we know what the estimated price will be for that card? It's numero uno on my list of things to buy. I'm hoping for $400ish.

yeah 2x1gb for this beast surely....

but does 2x512 ram give you 1gb ram actually/useable?ie will it still get up to the 512 ram limit at high res/settings?:shrug:

does r680 force afr or what?..as it isnt a cf card? or is it?

might be cheeepa to get 2x3870?

I don't know, 2 3870's have 1gig combine and would cost more to make seeing how its two different boards. So while cheaper to make the question is will it be cheaper than 2 3870's.

yeah but it has the advantage of only requiring one x pci-e slot:shrug:...then agin if its cheaper to make and amd push for r680 cf then maybe it will be good price.
nyway more to choose from:)
but it not rly a mainstream card...so how many will they make?

There was, what looked like an AMD marketing slide, posted in the original 3850/3870 thread that said $800. I doubt it will stay at that price. I'd say between $400-$500.

the first mobo doing a four crossfireX is MSI K9A2 platium.

the second one is Gigabyte GA-MA790-DQ6. a mobo have 4 PCIe slot but too tie for four dual slot cards.

It's possible that the GPUs could snoop eachother's frame buffers if AMD did their engineering right, but I wouldn't count on it.

As for the amount of memory in each card, you can probably expect either 1 or 2GB. If you look at the pictures you'll see that AMD has also put memory on the back of the PCB, so if we could get a more high resolution image we might be able to make out the density of the chips.

I as well.
As for those Inquiring minds(bad pun I know) who think RV670x2 is R680, I made a post after pondering their constant statements of R680=RV670x2.

So there are quite a few possibilities here...
#1 These new cards are NOT R680 and are simply RV670x2.
#2 R680 has extra features/specs.
#3 R680 IS RV670 but RV670 has a few things disabled, I already speculated this once.
#4 AMD/ATi decided to disappoint me, join Nvidia in being extremely stupid with their codenames.

Depending on what these actually are, if they are new cores(R680) or 2x RV670, I am somewhat dissapointed(if these are just two RV670) AMD didn't take UVD out and put two RV670 under a single IHS.

Funny, AMD/ATI's performance in DX10 is nothing short of craptastic compare to their DX9 performance, yet DX10 will be where Quad Crossfire is utilized (DX9 has a frame buffer limitation so Quad SLI or Quad Crossfire will be more or less useless, Tri-SLI probably works though). I can see that the not optimized driver excuse for low performance will probably be used quite a lot until the next AMD/ATI's true next gen card.

3870 X2 + 3870 = tri-cf

possible ?

wonder if these are something to actually look forward to... or should i just stick with the 3870CF

try $200 each for a total of $800 :rolleyes:

Hmmm, interesting thought. I wonder if it would work.

IF this works out then there should be a wholesale price for all 4 cards instead of having consumers by them 1 by 1

I think these are just meant to make the 'crossfire-solution' possible on 'single pci-e x 16' slot mobo's, and quadfire-solution on dual pci-e x 16 slot mobo's (like the Maximus i have here waiting to become my next gaming PC).

RV670 times two, 512MB GDDR4 memory times two, DVI-HDMI adapter - times two, DisplayPort... erm...

As you can see, this longer board is on the trail of the 8800GTX/Ultra PCB. Unusually, there is no significant increase in the height of the board, meaning this dual-GPU card will fit it a more compact chassis.

The price of 3870 X2 will be between 399 and 499 USD/EUR, 249 and 299 quids (yes, life sucks in Bligthy).

RV670 chips are working at 750+ MHz each. 775 MHz should be reachable by launch time. Who knows, maybe even 800 MHz for the GPU. When it comes to overclocking, we have no idea at the moment, but the memory should be able to work at 2.25 GHz, yielding in combined bandwidth of 144 GB/s. Not too shabby.

... confirms my assumption. 2xRV670/512MB 'crossfire' on a single card, so still a 512MB solution and not a 1GB.
So, 2 x seperate RV3870's in my Maximus would be the same as but €99,- cheaper than this one.

lmafo @ the size of that card. it looks like a tower block and i bet they are noisy as hell

great, if AMD can sell them @ 300 $ with a bundled case and psu they're gonna kill the market

I've read that this (RV670x2) is R680, is it confirmed?

I'm torn... The GT is a nice enough card but isn't quite up to the job @ high res. I refuse to get an nvidia chipset due to fsb limitations.

I have the Blitz so CF seems like my only option atm.

Here is the predicament - get 2 3870's for £275 (usually you'd pay £320 for a pair here) now, or wait for these X2's...

Shame there are no X2 benchies!
