I trust that the clock speed is still very appealing to XS members. Whether it has extra units or not is just icing on the cake.
960 SP(and likely expanded TMUs) is 20% more than what you have in RV770.Add in the extra GPU clock(13%-850 vs 750Mhz) and extra BW(10% higher GDDR5 clocks) and you end up with much powerful GPU than RV770.Quote:

If this is true I might switch from my (as-of-yet unpurchased) 285 to this. I've been looking for a reason to switch to ATI, but with nVidia currently whooping them in the single-GPU scene (which is the only scene I'm interested in), it's hard to justify.
Maybe people should wait abit. Since it could just be a RV770 tweaked for higher clocks as much places suggested....
I dunno, i just thought ATi will try to keep their winning formula, making a small and efficient GPU chip, 1120 SP 55 nm chip doesn't seem to oblige with that paradigm. :shrug:Quote:

Wait, can't we extrapolate how fast this chip will be at 950mhz by other people's runs at 950 using current 4870s on water/ice/LN2? Provided we believe that there are no extra shaders etc.

Well, I agree with you if you mean the people who just bought the newer nvidia and ATI cards. But not everyone has new cards and depending on how this is priced it could be a great card to buy instead of the gtx285 so you don't have to deal with multi-gpu'sQuote:

They should put better VRM's on HD 4850 and HD 4870 ,overclock it and rename it to HD 5850 and HD 5870. At least that's what nVidia would have done in this situation.

ATI Radeon HD4890 and Radeon HD4890 X2: Rumors from the Cebit
At the Cebit PC Games Hardware had the chance to talk to AMD's board partners about the Ati Radeon HD 4890 and a possible HD 4890 X2.
http://www.pcgameshardware.com/aid,6...he-Cebit/News/Quote:
The board partners want to remain anonymous of course and thus we can't guarantee that the following details are one hundred percent correct.
Based on the information we received during our conversations it seems like the Ati Radeon HD 4890 (Single) will compete against the Geforce GTX 260 and not the GTX 285, since it seems like for the Ati Radeon HD 4890 only the frequencies of the GPU and the memory were increased. Accordingly the calculation units aren't changed. Basis for the increased frequencies is the 55 nm production process, which has been quite perfected by now. 850 to 900 MHz appear to be possible for the RV790 GPU; the RV770 of the HD 4870 is clocked to 750 MHz. As the GDDR5 memory of the HD 4890 (Single) is regarded, AMD wants to reach 3,900 million transactions/s - RV770 based cards reach 3,600 MT/s. Those numbers indicate an increase in gaming performance of 8 to 20 percent, depending on game and sequence.
PC Games Hardware also wanted to know the odds for and against a possible Ati Radeon HD 4890 X2. From a technical point of view such a card shouldn't be a problem, but it remains to be seen if AMD will really invest time into such a prestige object. A Radeon HD 4890 X2 might hit the markets only if it can noticeably beat the Geforce GTX 295. Probably AMD will leave it up to the board partners to build such a card or they are looking for exclusive partners like they did with the HD 4850 X2 which is available from Sapphire only.
The Radeon HD 4890 is supposed to hit the markets on April 6. This date, which has been brought up by VR-Zone initially, has been secretly confirmed by the board partners. But as usual such a date can easily be rescheduled ad hoc. We were also told that the cards will cost 230 to 240, although it is unclear if the cards will have 1 or 2 GiByte VRAM initially.................
Good news!
4890x2 would beat the gtx 295 easy right? 8-20% improvement on the single card... so?
Sandbagging...Quote:

I thought HD4870 does that already.
I'd imagine the biggest gain from RV790 is lower power consumption, along with higher clocks - they have been making RV770 55GP with fixed variables now for over 9 months. In the mean time, AMD shorely has tweaked the arch and TSMC has been busy optimizing 55GP to make 55GT. It would be reasonable to expect higher performance and lower power from RV790 @ 55GT, not just one or the other.
hopefully the 5xxx series with new architecture will be out by the end of octuber and be on 40nm
i might just get the x2 verision for know when it releases and then sell it and get 5xxx series
Looks like ATI is going for 2 directions here.
RV740- unprecedented density on 40nm (it's scarily small)
RV790- unprecedented clock scaling on 55nm (if 1Ghz OCs are common and true)
RV870- combining both?
You're right. One would have to be a bone head to purchase the 285. It just doesn't make sense. This new card is the new king of the hill in terms of price performance ratio.Quote:

They might be, they put 5ghz chips on one of the laptop cards.Quote:

CeBIT 2009: An entirely new chip
We learned some bits and pieces on ATI's upcoming RV790 chip and we can now happily confirm that his is yet another 55nm chip from ATI.
The company didn’t want to postpone the introduction of the new card in performance segment and therefore did it in 55nm, while RV740 remains the first 40nm. RV740 just launched as a mobile chip, and we’ve seen it up and running, while the desktop part should arrive in the next month or two.
The new chip is a new architecture, but with some basic concepts taken from the RV770, that is why the chip will be significantly faster than anything based on the RV770. It is not just a speed bump and a better batch of RV770 based Radeon HD 4870 and 4850 chips, it is a newer and better chip.
It looks like this new chip will beat the GTX 260, and it could even get close to GTX285, but at a much more affordable price.
PcGamesHardware is probably wrong, as it is ALREADY wrong that the 4890 could only compete with the GTX 260, as the 4870 1GB already does that. I was always thinking that with 960 shaders and 48 TMU's, the 4890 would blow the GTX260 out of the water.
gtx 285 at least
gnt
The difference is small, 21 watts at idle and 5 watts at load.Quote:

mmmm new architecture :slobber:
But not as new as we are going to see at towards the end of this year, right? :confused:Quote:

At least ATI will have the fastest dual-chip card for a few months, if there's not too much of a delay...
I wouldnt be surprised if ATI actually had even lower running clocks on the RV790XT, like 725MHz or so. Notice how the 3870 ran at 775MHz and the 4870 runs at only 750MHz?
Eh?Quote:

LOL, didnt know that. I read about this once a while ago, but forgot.. I just thought that with all of the heat and added transistors from a bigger chip, ATI just had a harder time running it at an equally high clock. Remember how the 6800 Ultra ran at only 400MHz compared to the 5800 Ultra at 500 MHz?Quote:

that would make it a round 1000...
Or 1280 SPs @ a lower clockspeed to conserve power at both idle and load?
Heh, just suggesting.
I hope that there will be a dual OC version.
Which they cannot currently due without a overhaul of the current shader core...Quote:

I was hoping for a 40nm RV790 that would up the shaders in a SIMD from 16 to 24 but I guess that will have to wait for RV870.
Will the AMD RV790 Architecture be Something Different?
http://www.pcper.com/article.php?aid...e=expert&pid=1Quote:
Initial rumors had the RV790 pegged as a speed optimized RV770, which currently powers the Radeon HD 4800 series of cards. Recent information has hinted that there is far more than a simple speed increase, and AMD could be catching us unawares with a potentially exciting new part. I take a look at AMD's releases over the past two years and make a few guesses as to what we might expect to see.

Problem 1: If it were 220W it would definitely need 8pin + 8pin.
Problem 2: 100Mhz bump does not justify 220W (50W EXTRA) neither.
I do not want to seem very doubtful or wishful, but couldn't it hapen that whatever he used to get the info from the card (unless it was in the docs) did not show the correct details ?
True to that. It may be launched as silently as the RV770.Quote:

Hornet331,
The thing with RV770's idle consumption is, GDDR5 is to blame. RV770 GPU chip is very power efficient in idle and manual downclocking of the VRAM will drop the consumption to sub-30W figures. HD4850 idles around 25W at stock, without manual tampering...
Here's Josh's take on RV790.
http://www.pcper.com/article.php?aid...e=expert&pid=1

A Bit of History
The other day Fudzilla reported that the RV790 was far more than a faster clocked version of the current RV770 which powers the Radeon 4800 series. Initial reports were that the RV790 was to be a slightly optimized RV770 which would run around 150 to 200 MHz faster in core clock speed. Nothing terribly exciting to see here. Or so we were led to believe...
AMD will simply look foolish if the new card requires 6+8 pin PEG connectors, considering nVidia's success making GTX 285 into a 6+6 pin PEG connectors compliant card. And unless GDDR5 gets worse as it gets ramped up, the added VRAM capacity shouldn't affect the TDP THAT bad. But commenting on an attention wh*re poster is just like feeding a troll, perhaps i shouldn't even write this post, huh. :down:
nothing yet, but on card is paper stick with frequencies, another info about TDP and SPs is from PR slide, but i dont know if it is true! facts are frequencies + (PSU pins, cooler) ... nothing more ...Quote:

This is the biggest piece I've seen on a product that no one knows anything about but it offers some great insight into the thought and design process of ATI's release relative to Nvidia.

Latest rumor from reliable source says nVidia wants to put a GTX275 against the HD4890. If true that also says something about RV790 performance.
Is that the card nVidia wants to launch the same day as ATI, OBR?
that doesnt matter... hows jo avarage suposed to fix the short comings from ati. :rolleyes:Quote:

its definitely interesting how they predict what a card would be like if it was built a little larger on the 40nm node, just by doing some math. AMD/ATI did something great with the R700s, now keep it up for dx11 and opencl, and maybe my stock will go back up a little.
What I honestly think is that if the new chip was just an overclocked RV770, they wouldn't give it a different codename.
AFAIK, ATI never did that with codenames.
So a slightly higher clocked 260GTX? :p:Quote:

I hate ATI rumors, so chaoticQuote:
Did we forget to mention that the RV790 chip is 40nm?
ATI is spreading FUD around RV790 like they did with RV770. Simple.
Anyone knows nothing about the GPU for sure. Each source says something different.
GTX275 against Rv790? Let`s see - Rv790 is probably about 5-10% faster than Rv770 so it will be so close to GTX285 performance. If NVIDIA want to win this part of the game they have to do card with performance of GTX285 and with price at the Rv790 level. Then NVIDIA is releasing something like GTX275. OK - but what GTX275 is supposed to be? There is no possibility to push GT200@55nm with specs we haven`t seen yet. 240SP, 216SP, 192SP - all these specs are already here. Moreover a name "GTX275" is saying that we could expect something slower than GTX285. So WHAT NVIDIA could release against Rv790? The only way is launching a new chip (40nm?) IMO but unfortunately there is no info about any GT2xx in 40nm.
Yap, FUD spreading.
No one knows what RV790 will be anymore, except that we'll have to wait another month to be sure about its specs.
since no one knows exactly what the details are, this is a breadbasket pretense for when the product is actually released. if its what the market wants (probably 40nm) then the stock price will hopefully shoot up.
maybe GTX275 is 240sp, but only 448bit like the ones on the GTX295, thats the only combination they didn't use yet
an SKU between the 260 and the 285 would just be a waste of time for NV if this card really does live up to spec of being 20% better than the 4870....
Yeah, i`ve missed it ;) That`s the only possibility we have not seen yet. But on the other hand could this combination give NVIDIA a victory over Rv790 if Rv790 will probably be 5-10% faster than current Rv770 and GTX275 (with these specs of "half of GTX295") is supposed to be slightly slower than even GTX280 (i suppose it because of a name GTX275 vs GTX280/285). As i said before - IMO if NVIDIA want to win this battle it should present a new GPU (in 40nm) - GT214, GT215 or whatever one.
Dang I'm in the market for a new card...and these are right around the corner, what to do?! ;)
makes me sick all this rumors and stuff.
wouldn't be surprised if ATI is planting this news, fooling everyone around,
even tough they might bring a surprised as they did with RV770, but
i don't think so... 40nm TSMC process node is delayed... too bad
for their upcoming series.
ati is probably doing this rumors to confuse people :) therfore bigger supprise more money if they beat the 2 nvidia cards easily
( i died inside when ati said no 40nm , is 58xx series for octuber or june?)
Well its plausible, with a return to the 512bit bus the RV790 could -just possibly- compete with a GTX 285... But that wouldnt be like this industry, where bending over and talking out one's.... err, talking big, is all the rage. 256bits of fail onward ho ATI.
Also, after all this time there ought to be a way to squeeze wider buses on a smaller, cheaper, although no less complex pcb.... so don't come at me with the cost effective philosophy, that was thrown out the window by GDDR4 and 5 use instead.

Said by whom? If Nvidia actually reacts to RV790 in such a clumsy and ineffective fashion they've really completely lost it. But at least it'll be consistent with all the other bonk they've been doing lately.
I dont get it.... the 256bit gddr5 4870 has an excess of bandwidth... even at 900 core I don't see improvements in even synthetics more that 1-2% by raising my ram clocks 50 mhz.Quote:

On the CeBIT 2009 us 6 April was confirmed as release date by the RV790 of several partners. Now us new information was passed on to the current consumption.
So less river is to need after our enterprisenear sources of the RV790 in the Idle mode, than the RV770Pro in the no-load operation and under load reach a level of the RV770XT or are even somewhat under it. This has to do with the fact that one worked at AMD strongly on PowerPlay and also on a new 55nm manufacturing process, which is not to be compared with the manufacturing process of the RV770.
We will see whether these information is confirmed.
Lovely!Quote:
