AMD Plans RV775XT To Compete GeForce GTX 285


We were told about a new RV775XT core which is essentially a fine tune version of the RV770. However, little information was revealed at this point of time but i can say AMD is concentrating their efforts on RV740 instead. We are speculating AMD has been collecting the higher speed bins over the months to make this card out to compete against GTX285 offering. It looks exactly the same as the GeForce GTX 280 card but comes with 2 x 6-pin power connectors instead of 8+6 pins. We are able to confirm at this point that it has 240 SPs, 512-bit memory and 1GB GDDR3 memories just like the current GTX280. Expreview has provided more insights on the GeForce GTX 285 like 183W TDP and 110% performance boost over GTX280.

regards

this is insane this cant be true

If it said compete with GTX265 then I might believe it, but with the GTX285? To compete with the GTX285 you need some very special cherry picked chips and they would never be able to deliver enough cards. Would be a paper launch if they tried something like that. So I'd say they want to compete with the GTX265 with it, seems more realistic.

Is the 285 just going to be a OCed 55nm 280?

If the GTX285 is only 10% faster than the 280 then it wouldn't be too hard for a tuned/higher clocked 1GB 4870 to compete. Of course as we all know it's incredibly hard to judge "competition" due to constantly changing performance as drivers mature and games get patched.... then theres always those game that favour 1 type of architecture over another.

Yup, and lower power consumption, which may also mean there is more overclocking headroom. They should be around 110% of the performance of a GTX280 and their TDP is about 50W lower.

Basically what this article is trying to say is that ATI is going to give the "Super HD 4870" another kick at the can. You may remember the last time they tried this it resulted in the failure-prone Diamond XOC Black Edition. Hopefully if this article turns out to be correct, ATI will be slightly more successful this time around.

ok i read the article wrong lol

so in a game that yield's 55fps with gtx280, 285 will give 115? that's 110% performance boost, and that's also high hopes!:p:

obvious mistake on the 110% sentence :P
Should be 10% more ofcourse.
But I'm glad they are at least calling the thing a GTX285 and nog just a GTX280, which would mean you would have to get lucky?

Does that mean there's gonna be a GTX265 aswell, or is the 55nm version just gonna be 260 aswell?

And good thing Ati responds right away, keeps competition up!

Don´t think this rv770 with clocks up can do much to retain the crown against gtx295

all of this will drop the price of the 4870x2 eh? up here its 650bucks at the local comp store and 550-650 online! if i can nab one for 399 that would be nice. And WTF at this?->"AMD is concentrating their efforts on RV740 instead" any word one y this chip?

I like it all, now the GTX280's will drop just enough to go SLI :woot:

I feel sry for these guy cause they just screwed up their source -.-

Of course not, that job is for R780.

R780? What the heck?

Now theres a RV790, a RV775, a R780, a RV870, etc.

I think most of u are just wrong ;)

Well there is only one respin of RV770 which has 3 different names; RV770xtx/RV790 and now RV775.
R780 was being brought up in B3d as just a way of naming a 4890x2 or whatever it might be with the new binning.
RV870 is still 40nm.

I know that, but thank u for ur thoughts :)

RV740 is supposed to be AMD's first 40 nm. GPU. It will be the test chip to see what they can do on 40 nm. and to learn all they can before implementing it on more revolutionary chips. A bit like what RV670 was for AMD, a test chip to check what the 55 nm. node is like. All rumors though, but seems plausible.

I'm confused is this how it is?

R740 ~ 40nm R730 (4670)?
R775 = high binned R770
R780 ~ 40nm R770
R790 ~ 40nm R775
R870 = 40nm new GPU with DX11
R800 = 2xR870

Could be. But put simply, there are no solid facts and many of those codenames are made up by some random guy and not by ATI. There are and have been many rumors of a RV740 coming, which would be ATI's first 40 nm. chip, but nobody knows (except ATI and some people whom are under NDA) what the chip will be like. It could simply be a RV730 done on 40 nm., but it just as well be something different.
Rumors on RV740 so far say it has a 128-bit memory bus and 8-SIMDs, which makes it rather similar to a RV730. But those 8-SIMDs could just as well consist of SIMDs with 16 shader execution units per SIMD. Which would mean the card has 640 SPs, unlike the RV730 which has 8 shader units per SIMD and thus 320 SPs. To me the version with 640 SPs seems plausible as this would slightly increase die size to make sure the chip does not get to small to not allow for a 128-bit bus. By that I mean that the current RV730 might get too small to still be able to put the 128-bit memory bus on there if they did a direct shrink. Just my speculation though.

arent more and more companies ramping gddr5 production?
the production capacity should be there to implement it on mass production cards (much more cards than rv770, adding to that demand)

64bit and that memory wouldnt be a problem... and even cheaper pcb's :D

If they add GDDR5 to it then it could become a HD4830/9800GT killer. They should make it 560 SP's instead of 640 to make it competitive with 9600GT instead of their own if they have plans to use GDDR5. later they can make HD5670 with 640 SP's and GDDR5 to replace HD4670. For now these are all my fantasies. We don't even know if they plans for releasing a RV740.

you all have seen the great strides r700 arch makes at higher clocks, if AMD releases a GPU the can do 950mhz at stock settings (nothing more than some voltage and cooling at this point for some cards) then I think it will give the 285 a run for its money. if it is lower clocks it will be a failed attempt :2cents:

I was more thinking-
RV740 = 40nm ~4830/4850 performance.
RV775=RV790= new RV770 revision on 55nm
R780= 2xRV775/790
RV870= 40nm nextgen evolution of RV770
R800= 2xRV870

useless, we need 2gb gfx cards to play gta4 on max settings :p

Why should they? The 4830 is made by disabling parts on the die, which is a bit of a waste once you do have good yields. By the time something like this (hypothetical RV740) comes along the yields on their RV770 should be well enough to not need the scavenged part (4830). So the hypothetical RV740 would be perfect for AMD to replace their by then silicon wasting 4830. Just my theory though.

110% increase in performance over GTX 280? Holy crap, eh? I'm down.

It offers 110% of the performance of a GTX280, 10% performance increase.

Should read the original source...
http://en.expreview.com/2008/12/11/5...gpu-cards.html

Cherry-picked RV770s with better cooling and better power regulation could hit the 1Ghz mark, making it highly competitive to the GTX280.

I just hope this is not another lame-and-bundled-watercooling-only edition, those always suck..

So what, kinda in the neighborhood of an 8800 Ultra?

As far as 40nm, I can see an RV740, but smack-dab midrange performance. However, I can't see a 40nm derivitive of RV770. I'm sure that shrinking the RV730 would be much easier compared to shrinking the RV770. It makes sense from an engineering standpoint.

I would imagine the RV740 is close to a 40nm RV770.
Shrinking RV770 to 40nm would put it in the 140-150mm2 range, even without the sideport it doesn't seem possible to fit a 256bit bus on there.

My Speculation for RV740-
40nm
~600-700mil trannies
~100mm2
700-800mhz core
480-640SPs
128bit bus
3.6-4.4ghz GDDR5 in 256/512mb/1Gb flavors
58-70Gbps of bandwidth
32-40TMUs
8-16ROPs
~100w TDP

RV730 was ~3870 performance, IMO they need something to fit between the 4670 and the 4830 which should be the RV740.
If RV740 turns out to be a near straight shrink of RV730 then I expect this speculation to be a RV830 in Q3.

fake.

It's a lot more easyer to start selling RV770 at 850mhz with a better cooler :yepp:


& in Anandtech review about RV770, AMD said they working to not get the halo in performance, but the halo in mainstream. Creating a RV775 would be a big mistake, and will cost a lot for nothing to gain :rolleyes:

RV870 not out before Oct of 09? I think that seals the deal, this is misinformation by AMD so Nvidia doesn't know what to expect.

This reply is necessarily not for you, but more for everyone.

I am quite sure Nvidia has a tad better people guessing whether or not the specs are fake and when it can be expected. Heck, these people have been working on this kind of stuff like over a decade and then there is this "Xtremesystems forums" where people suddenly know it better than engineers at Nvidia/ATI.

How good were they on the RV770/R700 launch, price, and performance? The indication is they were not. It wasn't until about a month before GTX 200 launch when AMD realized how well priced/performance their RV770 was. I am pretty sure they go off the same news reports we go off of, which are sources from other vendors in Taiwan, China, etc.

They still have a lot more knowledge and experience with marchitectures, especially VLIW ones than any of us has. They know what is possible and what is impossible by way more accurately than any of us.

AMD Sets RV775 to Chase Down G200b?


Sources tell Expreview that AMD is working on a new graphics processor (apart from the mysterious RV790), as an immediate reaction to the 55nm high-end GPUs NVIDIA is set to release. NVIDIA on its part is working on GeForce GTX 260 (55nm), GeForce GTX 285 (successor to GeForce GTX 280) and the dual-GPU monstrosity, GeForce GTX 295. To rival this, according to the source, AMD is working on the RV775 and derivatives based on its yields' performance.

These GPUs are slated for January thru March 2009. It has some very interesting specifications. To begin with, 840 stream processors. While stream processors on a current generation RV770 cannot be added/subtracted in quantities of 40 stream processors, perhaps, the increment of 40 SPs is derived from an extra ALU cluster the RV770 comes with by default (which helps in die harvesting, where the spare ALU cluster makes up for any damaged cluster, thereby improving yields). This would require near-perfect GPUs in the making (if re-engineering of the RV770 on a large scale is to be avoided). Another interesting point is regarding the smaller die. At this point we are clueless as to how that is possible without re-engineering the RV770 at a large scale. Treat yourselves to the specifications meanwhile:

can't add that little amount of shaders and get less transistors.

it would have over 1 billion and 900 shaders for a top part. adding half a row a shaders isn't going to do much t it's levels already.

Also, I dont believe AMD will ever launch a performance part with 512Mb from this point forward. As we have seen with the 4870, 1Gb gives definate performance boost. It is also good marketing along side a potential 285 w/ 1gb.

These numbers may very well be real. However, I didn't ask around myself lately, so I can't comment on their validity. I'm just saying that from my understanding a chip with these specs could exist with current technology.

Smaller die size is attributed to removal of UVD function, now that STREAM functions are online?:shrug:

Plus the possible removal of the sideport.

Confused by the 1400mhz, 2800mhz GDDR, clock. GDDR4?
Why? 90Gbps vs 64Gbps...

Have to agree seems like misinformation.

Well, the whole XT nomenclature guarantees this info isn't from a 100% "reliable" source...

A big piece of FUD in my honest opinion

110% of a card is just 10% better. And they are making this a huge deal?

I agree with the poster above don't miss interpret the numbers or maybe they wanted us to think of it that way maybe they could get a lot more ratings if they put 110% instead of 10%

RV770 -> slightly faster card is being considered, but no new core -> RV870

Most of the code-names in this thread are made up.

//Andreas

I hope they keep it simple and just call the faster revision 49X0 instead of calling it the 5000 series. Would be less confusing. The card won't have any new features and no drastic performance improvements and thus no reason to introduce a new family just for a minor revision.

RV870 will be out second week August 09. I'am Nostradamus.

ATi cut out sideport and I think they should've cut out the DDR3 controller too, just use DDR5 for both the Pro and XT versions since chip prices aren't that high anyways. This could easily make room for 960SPs, 48TMUs and still have less transistors than the original RV770.

Sideport will probably make a comeback with RV870 though.

heh :) Any of this info whether it's a disinformation campaign or not is really gonna be irrelevant come January. Disinformation campaigns only work if the other side is listening. They might see it, but it's not gonna have any affect on what they release and when they release it. nVidia doesn't have to guess anything. They already know what they have. They are focused on their own race. They aren't interested in what's happening in the other lane.

After AMD's big effort of spreading misinformation before the RV770 launch I don't think NVIDIA is listening to anyone right now.
