Hi all here some speculations I have for the not released GeForce GTX 790, since the GTX 590 & 690 were made, I think the GTX 790 will be made in a similar way. the GTX 590 like the 690 are Dual chip cads of their high end single chip series cards. GTX 590 = 2x GTX 580 with 2x 512 Fermi CUDA Cores & 2x 1536MB 384Bit GDDR5, but slightly underclocked than a stock GTX 580. GTX 690 = 2x GTX 680 with 2x 1536 Kepler CUDA Cores & 2x 2048MB 256Bit GDDR5, but slightly underclocked than a stock GTX 680. Hereby I see a possible pattern for the GTX 790, but then it would look like this: GTX 790 = 2x GTX 780 with 2x 2304 Kepler CUDA Cores & 2x 3072MB 384Bit GDDR5, but slightly underclocked than a stock GTX 780. If there is any GTX 790 news, please post here If any of you have an idea, please also post

I think you are right and I do as well see a 790 card boasting 2 underclocked 780's with 6 GB of memory. Im curious to know what the power consumption would be on these bad boys. Right now in my folding rig I have 3 590's and I have to use 2 power supplies (AX1200 + AX750). I would love it if I can get away with only using 1 power supply for 3 790's.

A 790 is not gonna happens for sevral resons. One is that 780 never gonna see 6GB Vram unless the card is named titan. The 7-series cant be compared to the 5 and 6 series as they did not take the 580 renamed it to 670 for the same price and letting 680 take a higher pricepoint and using different GPU than the next card in the line, the 670 as this time will tell the story with only titan and 780 having the badass GK110.

Yeah I think the 700 series will be very limited until 800 comes out and then will see the same series of cards as the 500 and the 600.

Wonder if the GTX 780 will be a short stop vs the GTX 880. Meaning we won't get a dual GPU card this generation but will see a GTX 890 instead..?

Well keep in mind it's 2x 3GB not 6GB the VRAM buffer is always half the total VRAM size on any Dual Chip card. But as the GTX 790 goes, I think it is possible, didn't we have a similar thought of the GTX 590? With it's very power hungy GF110-375-A1's ? Clearly I can very well remember that many did not think a GTX 590 could be done, due to extremely high power consumption. But as we have seen, nothing is impossible and GTX 590 was made, even it was made in very limited numbers. So due to that, nothing is impossible. This is something we have to be very aware of, AMD even made an official variant of the HD 7990, this thing consumes even more than 375 watts and still it made it to the market, so I reckon that a GTX 790 is very well possible, I think it will happen. It has one major purpose, which is to beat AMD's HD 7990 and take the number one place of the world's most powerful VGA card on a single PCB. It is obvious that it's not for the everyday user, it's to have the highest performing VGA card on the market, it's the pinnacle of the grill, you will pay a massive amount, but you will get the best, Dual Chip cards are ideal for system with only one or two PCI-E Slots and small factor systems if the user wants something very powerful in it, ideal for Lan systems which have the size of a barebone for example. 3dfx had this idea with their never released Voodoo5 6000, NVIDIA had this with the GTX 295 even many thought that a Dual Chip G200-400-B3 based VGA card would never take place, but it sure did, even in two different variants if excluding the ASUS MARS. Hereby I speak of the Dual PCB GTX 295 with HDMI connector and the cheaper produced single PCB variants without the HDMI. Personally I have seen many crazy VGA card designs as had over 550 of them since 1994, something like a GTX 790 is very well possible, we will just have to wait and see, I'm like If any of you have news or rumors of the GTX 790, feel free to post it here, just a reminder hehe

I for one am with you on this. They did the 590, they did the 690, why not do a 790? The power consumption on 3 590's is huge, I want to be able to power 3 x90 cards using only a 1200W PSU. I think 300W per video card isnt too much to ask.

Its not the power consumption but the turn around time needed. I'm sure they've been working on it but makes me wonder if they will or not. Guess we'll know in a month or so.

Completely possible- I think the 4XX series is the only card they didn't make a dual version of in quite some time.

Well aware of that, afterall i had two of the biggest failure on that side, but the way i read it was that it is a 790 based on two 6GB 780:s witch never gonna happen. I still see no point for it nomatter the need with some to have that kind of card but that is just due to their wrongpurchas that lock them to atempt compromises to pull things of rather than do it the right way with no strangulation.

It wont happen NVidia will not want to dip into their higher end market that is the Titian. If amd does not offer something of almost equal to better performance it defiantly wont happen.

So yeah, we''ll see and wait this off

Still 100% pointless when 2x780 will fair better and also has a combined TDP of 500W and a 790 MAX can have 300W as per standard even if 375W might be doable but we have reach the end of where doubleGPU is based on the biggest GPU and 790 might only be renamed 690 and price and everyone is happy as you get a doubleGPU card in the 7 series and it is cheap to do with a bioschange for nvidia. expect 790 to be like the old 460twincardthing but based on 770.. i mean 680.

Incorrect, it's not not pointless for those that only have one or two PCI-E slots most motherboards have 1 or two slots and no more, we all know that a Quad SLI setup always outperforms a 2-Way SLI setup of a similar GPU based card, as for them Single Slot PCI-E based systems, take barebones as an example, a Dual Chip VGA card is the ideal solution, I see market in this and I would even invest in it myself. When going High End most people don't care about TDP or price they just go for the best and that is it, this is how I think also, I just want the best for a Dual PCI-E setup, I am using two GTX 680's atm since I could not afford anything more, but you would not see me buy something cheaper like the castrated GTX 670 for example. I had Dual EVGA GTX 295 Red Editions before my GTX 680's and in Quad SLI they were always faster than 2-way SLI GTX 285's even 3-way SLI setups were often slower also, CUDA Wise they came to a similar GPGPU performance to that of four GTX 275/280/285 GPGPU's, since they have like those 240 G200 CUDA Cores per GPGPU. If I can afford 4 GPGPU's over two VGA cards I would do it any time over any Single GPU based design, because for my setup four GPGPU's of the same type is always better than two.

To make sutch compromise they have the wrong components for the purpos of wanting dual GPU:s and that make it their own fault when buying. But for the sake of it just take the 690 BIOS, rename the card to GTX790 and you got your card and you paid nothing for it. Perhaps i a period of 2-5 month they have even mord bad GPU:s that dont qualify tor GTX780 that they can nuke even more and use dor a short run of a GTX 795. As for long term card i see no market when 780 and titan filling the important part it that still make the profit.

All the Dual GPU users do see a use. Power wise two GF110's which were used for GTX 590, use more power than two GK110's ;) So Impossible? Absolutely not and money wise NVIDIA has loads of it, they can pull this off I am quite sure about. If there is a way to earn money on something big like a GTX 790 and also maintaining the world's fastest VGA card in a single PCI-E Slot, I don't see a problem with this The HD 7990 is today's most powerful VGA card, which in most benchmarks it beats the GTX 690, especially in Ultra high settings with high FSAA & AF settings enabled. The GTX Titan get's crushed by the HD 7990, majorly thanks to its new drivers, thus NVIDIA needs to take care of this and release a GTX 790, just to retake the crown Nothing is impossible in VGA land, I have seen that too many times man, I'm a true vet as that goes. Besides similar doubts went around about the GTX 295 & GTX 590, and still they appeared Oh well not that it matters, this topic is just about the speculations I had, they still make sense to me, as I have seen many strange designs to which I would never thought would hit the market, the XGI Volari V8 Duo was a very good example, they looked like this: Here a naked PCB shot which shows the layout of the ram and the XGI V8 Ultra GPU's: In 2003 XGI Technology replaced Silicon Integrated Systems which was SiS for short, more about that here: http://en.wikipedia.org/wiki/XGI_Technology

Now that could devastate the industry hah anything is possible but 2x GTX 780 chips and underclocked would eb more realistic, the Titan Ultra should be a fully fledged GK110 GPGPU with the full 2880 Kepler CUDA Cores :) If this won't happen I speculate that Titan II will be Maxwell based, GM110-400-A1 perhaps, just a mere guess. GM110 meaning Graphics Maxwell 110 ;)

Didn't we have this talk when you dreamed about a dual-Titan? Let get some numbers so we aren't guessing out of our butts too much: - GTX680 at 195W and GTX690 at 300W = 53.8% extra power w/10% GPU downclock.
- GTX580 at 244W and GTX590 at 365W = 49.5% extra power w/26% GPU downclock.
- GTX275 at 219W and GTX295 at 289W = 31.9% extra power w/9.9% GPU downclock -- best scaling per Watt.
- 9800GTX at 140W and 9800GX2 at 197W = 40.7% extra power w/12.5% GPU downclock.
The primary reason that power isn't double isn't due to downclock alone, it is due to the other shared circuitry on the PCB, which means the power on a single-GPU card isn't all coming from GPU and Vram. Anyway, the trend shows that the lower-wattage single-GPU means the dual-GPU counterpart gets to keep a higher GPU clock, but high-wattage single-GPU means a castrated dual-GPU card. Therefore a dual-GPU product using a 28nm GK110 will be castrated just to keep the power down: A GTX790 would have a 350W maximum graphics card power at reference speeds. GPU base clock would be 650-700MHz. It will be like 7950GX2, but faster by two orders of magnitude costing only twice the power, seven years later. How's that for perspective? So seven years from now, graphics cards will have 50 times the compute power of today probably at the same wattage range, Gawdayum! Anything is physically possible, it is always a question of money; and not just unit price, rather market demand and competition. Since GTX690 and HD7990 throw punches at each other, there is no need for anything faster. But, GTX680 and HD7970 also threw punches yet nVidia brought Titan anyone on the caveat of the $999 price tag. So if a dual-GK110 comes anyway, it will be very expensive because there is no competition for it. Be careful what you wish for, don't be one of those people that take competition for granted and complains about price... aka_STEVE_b I think the 4XX series is the only card they didn't make a dual version of in quite some time. Asus would have made the first GTX490, but it was canceled. It consisted of two GTX470 chips and rated for 375W. When nVidia improved the circuitry, they allowed GTX590 to not only outperform it but consume 10W less.

All the Dual GPU users do see a use. Power wise two GF110's which were used for GTX 590, use more power than two GK110's ;) So Impossible? Absolutely not and money wise NVIDIA has loads of it, they can pull this off I am quite sure about.
If there is a way to earn money on something big like a GTX 790 and also maintaining the world's fastest VGA card in a single PCI-E Slot, I don't see a problem with this
The HD 7990 is today's most powerful VGA card, which in most benchmarks it beats the GTX 690, especially in Ultra high settings with high FSAA & AF settings enabled. The GTX Titan get's crushed by the HD 7990, majorly thanks to its new drivers, thus NVIDIA needs to take care of this and release a GTX 790, just to retake the crown Nothing is impossible in VGA land, I have seen that too many times man, I'm a true vet as that goes.
Besides similar doubts went around about the GTX 295 & GTX 590, and still they appeared Oh well not that it matters, this topic is just about the speculations I had, they still make sense to me, as I have seen many strange designs to which I would never thought would hit the market, the XGI Volari V8 Duo was a very good example, they looked like this:
Here a naked PCB shot which shows the layout of the ram and the XGI V8 Ultra GPU's:
In 2003 XGI Technology replaced Silicon Integrated Systems which was SiS for short, more about that here: http://en.wikipedia.org/wiki/XGI_Technology
So what 7990 is a dualGPU card, i would be shocked if it did not beat titan but it is also the mother of all MS. Put a OC on 690 and problem solve for free or almost free after paying the enginer for his work to find the OC and create the new BIOS for the 690 that they name GTX790 to fit the renaming campain. Asa i said dualGPU user is locking them self in so they have to use a dualGPU or change platform to cover up the misstake of not buying the correct stuff from the start and i did the misstake twice to buy a dualGPU card and the way quadSPI/CF scales it aint worth it besideds a very few numbers of titles, for majority of titles triSLI/CF is the sweetspot and will remain to be so. By doing it for free they can continue to change 1000USD or better yet charge 1200USD for the renamed 690 and make a buck or two from the last souls that defend dualGPU cards.

Uhm as GTX 490 goes they made as it's GPU's go, if you look carefully at this photo: It uses two GF100-375-A3 GPGPU's which are the same GPGPU's the GTX 480 uses, the GTX 470 uses the GF100-325-A3 ;) It's actually a Dual GTX 480 in one hehe. As for me complaining about high prices? no man you might want to see my old VGA card collection: Thumbnails work, only some don't show since my gallery was hacked once :( The cards I still have are these, still a neat lot hehe As price goes hah I'd even pay more if I could get my hands on an Engineering Sample xDDD But I guess they are always the toughest to find As NVIDIA GX2's go I have had them all, kept my favourite ones the EVGA GeForce GTX 295 Red Editions of course :) EVGA 7900 GTX Duo / 7900 GX2 SC Edition - MSI 7950 GX2 - XFX 9800 GX2 XXX Edition - 2x EVGA GTX 295 Red Edition I have had all original GX2 designs, so as a Veteran Dual GPU & Quad GPU user, I sure know what I want, GTX 790, since it's not only games I do, CUDA I find extremely handy and if I can get four GPGPU's just over two PCI-E x16 slots I am happy as can be. Four GPGPU's is always better than Two When doing CUDA workloads

harrier808 Nvidia allegedly working on dual-GPU, GK110-based GTX 790 http://www.techspot.com/n...110-based-gtx-790.html It will be fun to sit back and watch how many of those rumors hold true. I wonder "If" this 790 happens if it will be able to run Surround 120Hz with the proper connections needed or not... If it does, I might get one. If not, second Classy 780 for me... ANd that second rumor about the so called "800" series... Interesting...

My $0.02: I think Hawaii-XT is built on 28nm and will close the gap between HD7970 GE and GTX780, but won't beat GTX780, evident by rumored price barely $50 less and not cause a price war. Doing so, if AMD pulls a Fermi 2.0 move to improve performance without a power increase, it would level the playing field where both nVidia and AMD have products in a similar price range ($600-650), similar power consumption range (250W) and performance range as well-- only this situation would allow for both companies to race towards making a dual-GPU product. It is anyone's guess on performance; historically the separation between GTX580 and GTX590 implied the latter had to be downclocked to save power and ended up barely 50-60% faster than GTX580, while HD7990 almost scaled equal to GTX690 in comparison with the single-GPU counterpart despite the power consumption level. GTX590 drew the same range as HD7990, 365W versus 375W; does this mean AMD is better at scaling than nVidia despite their drivers? I don't know, we'll see. Guess on specs: Dual 2304-CUDA product will have their base clocks 20% lower than GTX780 to compensate power, thus performing in between GTX780 SLI and GTX770 SLI. The dual Hawaii may have their total of 5120-sp running within 10% of Hawaii-XT's frequencies. Both cards will have 3GB GDDR5 per GPU.

Even if they do make one, which I doubt for reasons Lehpron mentioned (he knows his stuff"), I still wouldn't want one. Dual gpu cards have been garbage compared to single gpu cards in sli, from all of my experiences.

it seems that my speculations are going to be quite correct after all as the GTX 790 would lead http://www.tomshardware.c...titan-ultra,23988.html GTX 790 = 2x GK110-350-A2 with 2x 2496 Kepler CUDA Cores & 2x 3072MB 384Bit GDDR5 This is what I am speculating, a GK110-350-A2 as being the second GK110 revision as the new GPU will also be used for the GTX Titan Ultra but with the full 2880 Kepler CUDA Cores it's code name would be GK110-450-A2, just my speculation of that

Since the GTX 780 Ti aka GTX 780 Titanium is coming which has these specs: GTX 780 Titanium = GK110-450-A1 with 2880 Kepler CUDA Cores & 3072MB 384Bit GDDR5 Personally I think that the GTX 790 is still a great possibility, since AMD Might launch their new Dual chip card the speculated Radeon R9 290X2, to compete with this a GTX 790 would fit in very well but still with these specs: GTX 790 = 2x GK110-350-A2 with 2x 2496 Kepler CUDA Cores & 2x 3072MB 384Bit GDDR5 More cores than a GTX 780, but less cores per GPGPU than a GTX Titan & GTX 780 Ti, I think it can make sense, as for core clock down speed about 10% the same with GTX 690 compared to GTX 680. So yer due to this speculation I have, I think that the chance of a GTX 790 happening is very well a possibility.
