That's old news. It was at Nordic Hardware back on February 15:

I don't think the prices will hold because the latest from Digitimes regarding the prices for the two 3850 x2 models (512 and 1 gig) place it at $299 and $379.  
 
I can't see a 4850 less expensive or the 4870 priced the same as the lower end 3850x2. The 4870 is expected to be as fast as a current 3870x2, so that bodes well for the 4850 being as fast as a 3850x2. No one would sell a dual GPU card for more than an equivalent single GPU card.

@yipsl - somebody else said the same thing on that vr-zone page.  Maybe this is confirming that the specs from back in february are the true specs, not the 800+ shaders rumour thingy that was flying around a little while ago.  If the 3870 gets a 50% boost, thats gonna bring it into 8800ultra territory, at last....

If the 4870 can really push performance upto 8800 Ultra levels then Nvidia are really going to need to pull something out of the bag, otherwise the 4870X2 is going to absolutely whip their entire line-up. :)
'tis gonna be a good year for graphics cards!
I certainly won't be changing mine until AMD and Nvidia have release their new stuff!  :D

Ja, there's hope!  Those Idle wattages are what really impress me though.  I know my 2900XT still pulls something nasty even at idle.

OMG, WTF, can't AMD/ATI come out with something that will outperform an ancient ultra after almost two years???,  Heck that goes for Nvidia also, without resorting to glueing to cards in one slot.  so sad....

Yes. I think by the end of this year early next year we'll have 6 core Helmies and lots of gpu power to push threw them... then people will be talking about crysis II

i wonder how much processing power is inside that case next year!lol

250W? Thats what reasonably equipped computers draw in total...

RV770 is in production, 480 SPs and 32 TMUs indeed

some new info about the cards, looks like they are on schedule

That sucks about antialiasing though. I wish AMD would have stuck to the more traditional approach (AA in the ROPs (RBEs?))for at least one more generation.

didn't know it was old news, was it still considered a "rumor" back in Feb?

Just my two frames' worth.

Yeah the Hartware.de article mentions that it will double to TMUs to 32 but leave the ROPs at 16.
 
That will reduce the major bottleneck IMO, but with only a 50% change in shaders, then if the nV card is as big as predicted, then the RV770 won't be competing with it directly and will require the X2 configuration at least, and really that alone will be inefficient, so the R700 better be dual die single package for efficiency to match/beat one big chip IMO.

I'm still concerned with R600/RV670's poor transistor count to performance ratio. G92 creams RV670 while using only (relatively speaking) ~88 million more transistors. RV670 may be slightly more feature rich, but in the end these cards have to perform, and they just aren't for some reason. Hopefully it's a TMU bottleneck and we'll see a disproportionately large increase in performance with the doubled TMU count...

Tis already a great year for graphics card, at least pricing wise.  Our dollars get much more than they were a year ago.  Remember when best choices were $300 for 8800gts 320, $400 for gts 640, and $500 for GTX?

Agreed, looks like dual core in one package is where they might go for the enthusiast level chip.  I just hope they have the proper logic to circumvent reliance on drivers.  AMD can't afford to mess up R700 like R600.  
 
I hope AA is finally fixed, lately we can't trust anything AMD says until the products are 2nd party benchmarked.

I know, I am still stuck with my 8800GTS 320MB!  But not for long, just ordered a 8800GTS (G92) for $207 from newegg.  I went cheap so that I could hold out until RV770 and GT200 come out.
