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

http://www.nordichardware.com/news,7356.html

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....
March 28, 2008 11:33:27 AM

i cant wait untill Nvidia's next gen GT200 GPU comes out!!!!alot happening this year in both CPU+GPU
March 28, 2008 11:57:17 AM

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
March 28, 2008 12:00:57 PM

i wonder how much processing power is inside that case next year!lol
March 28, 2008 12:22:55 PM

250W? Thats what reasonably equipped computers draw in total...
March 28, 2008 12:26:05 PM

didnt you know graphics card draw more power then a cpu does!lol

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?

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.
March 28, 2008 3:41:44 PM

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.

That's hell of a bargain for a 8800GTS 512!

It sure is. I smell a rebate :p 
March 28, 2008 6:21:00 PM

only $30 MIR, $237 down isn't bad either!

God I know! I paid 400 for the old school 640 GTS, then $250 for its SLi twin brother a few weeks ago.

I'll get a 4850 for my wife's 690G board once I put a B3 triple core in. That should hold her over. If I go CrossfireX, it will be next year with AM3, Deneb and DDR3.

I just got an ASUS 780G board that's waiting for a Phenom 9850. That should be decent with a 3870x2 until February next year. Hopefully, 8.4 or 8.5 will improve over 8.3's crossfire performance. I see some serious boosts, but not in every game I play.

It's always a rumor until the cards are actually in the hands of Anandtech, Tom's, Xbit Labs and other benchmarking, review sites. It's all based on leaked specs, and specs can change prior to release.

It just sounds to me that the release of the 3850x2 is too close to the old release date of the 4xxx series. So, something's got to give there. 4850 sales would take away from the 3850x2. I'm guessing the 4850 won't launch with the 4870 and 4870x2.

Dude, no sh!t. The ultra is a dinosaur, I would sure hope that they can do better than that. That is setting some low standards on ATI's part if they launch a new generation that matches the ultra performances. :pfff:

I think the 3850x2 is just a short term product, just like 2900pro, it is only meant to get the rest of the rv670 chips sold before the launch of the hd4000 series

Ultra performance for 100 bucks might catch my eye if they can do it.

The 2900 Pro stayed around longer than I expected it to. The 2900XT is still at Newegg for $479:

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I couldn't see anyone getting that when a 3870x2 is $419 to $429:

http://www.newegg.com/Product/ProductList.aspx?Submit=E...

I think my MSI 3870x2 is okay. It doesn't overheat or anything. The fan's quiet. It just gives low 3DMark06 with the CPU I have. Yet, there's an open box at Newegg for $399. When I didn't have a PSU with an 8 pin connector and I contacted MSI to see if they had one, they said "return it". That sounded odd. I just got a new PSU and it's been running fine ever since.

Maybe I need to get a utility beyond CCC Overdrive or RivaTuner to take a look at it. What about ATI Tool?
