Damm i cant shift this headache so im gonna leave this info with u and have a kip and see later if it makes sense

The "rumour" if real is that GK110 is a dual gpu gk104, it is the successor to NOTHING because there wasn't an equivilent card before, it WOULD be a successor to a dual gpu 560ti(actually there is one but not an official Nvidia one, just a daft EVGA one iirc).

Yup thats what i said above and now i think its right when we look at the 7 series branding in the link i posted.There perhaps is going to be a filler in between the top end dual and single gpu cards called the 785 GTR using 2x GK104 cores which is the GK110. Its called the GTR 785 and is about 20% slower at most than the TOP end dual GPU monster.It sounds about the same as a card that today if it existed would be using 2x GTX 570 on one card and coming just behind the 590 but above the 580.So guys if you are using 570 GTX in SLI and wished it was on one PCB.In future u may just have your wish!

The 580 replacement seems to be a single GPU GK112 with 512bit ring bus.It cant be GK110 as thats listed for the GTX 790 – Dual Chip Flagship/2xGK-110 (Replacement for GTX590) but if GK110 is really 2x GK104 cores then thats 4x GK104 cores for the 590 which makes no sense and as i can grasp has never happened in the history of GPU's.

So surely its 2x GK112 GPU's for the GTX 790? Nothing else seems to make sense.

So in essence it would be

GTX 790 – Dual Chip Flagship/2x GK-112 (Replacement for GTX590)
GTR 785 – Dual Chip / GK 100 /(Offers dual GPU at lower cost)
GTX 780 – Single Chip Flagship/GK-112 (Replacement for GTX580)
GTX 770 – Performance Segment/GK-104 (Replacement for GTX570)
GTX 760 – Mid End Segment/GK-106 (Replacement forGTX560Ti)

A gk104 x2 card would likely be noticeably slower than a gk112 x 2 card. Much more than 20%, IF they have full clocks and no power trouble.

In reality both because of cpu limits being more apparent on high end sli/xfire and because of power, heat, throttling and tdp design limits it could be a heck of a lot closer than 20%, basically not noticeable difference.

Of course, a 2x gk104 is likely to have a heck of a lot less memory than a 2x gk112, meaning the area you might want to use all that power could be memory limited on one card, and not the other.

It's all daft though, and almost irrelevant. The first graph is almost certainly fake, and in all likelyhood there won't be a dual gpu gk112, because of power limits.

To get the performance improvement they want, you're probably talking about a gk112, being something like a 350W card, which would mean a "new" gtx 590 being something along the lines of a 600W card with lower clock speeds and reduced bus, and not nearly twice the performance.

Which is why seemingly early on the rumours are all about a dual gpu midrange card and not a dual gpu high end card.

I expect Kepler to comfortably outperform the 7970 which currently holds a temporary premium price. I also expect the GTX780 to come in at around $550 (£450) because it will not sell at $600+. The 7970 will drop like a stone, and AMD will lauch tweaked replacement (possibly with additional shaders) to make up some of the difference. AMD will because the budget choice at sub $500 and NVidia will be the performance choice above $500.

Pretty much bang-on what I'm expecting as well - although I wouldn't discount the chance of the GTX780 coming in at $599.

I actually wouldn't count on the GK112/780gtx actually arriving at all. Firstly it seems almost certain from a whole host of leaks that there is a dual gpu gk104. If so, this WILL beat a GK112, there is NO question of that.

Meaning, firstly, Nvidia have little reason to care all that much about a GK112 for gaming. The Gk104 will be faster, and will likely cost less. Because the GK104 will be faster, releasing their bestest single gpu later on will seem somewhat, muted as it will come in under GK104x2 performance, and will be CLOSER to 7970 performance. Considering AMD should certainly have a 7990 out by then that will also almost certainly beat the GK104x2...... releasing, months later a very expensive to produce likely 500mm2+ chip, that actually moves Nvidia performance towards the 7970 rather than the 7990........ won't look good. IE, 3-6 months later, they put out a card that is slower than something they already have, and less competitive with AMD, but also likely has worse power efficiency than the GK104x2, will cost a bomb and won't do much of anything for anyone?

AMD won't launch a tweaked replacement, the second Nvidia release anything, they'll simply release a 7970 with a new bios with 1150Mhz clocks and 300W tdp. Hopefully they'll do the right thing and allow 7970 buys to upgrade their bios without voiding warranties and let everyone have faster cards....... not too likely.

an overclocked gk104 will struggle badly to beat an overclocked 7970, IE, probably won't come close. The 8970 could quite seriously be very close to release before we even see a gtx780(if we see it).

As for price, well, the GK112 if it arrives will realistically have to be priced below a GK104x2, and after the GK104, 7950, 7870, 7850, 7770, 7750 are all out......... we'll have to see where prices are before then.


I think two things will happen, they'll find it hard to justify a Gk104x2 costing more than a 590gtx, especially when its not very close to a 7990, and this time I think AMD will have their dual gpu card be really good value again(like the 3870/4870) with the price significantly below the price of two separate 7970's....... even after those prices drop as the rest of the ranges come out and cause Nvidia/amd price fighting.

This isn't the rumour, and its complete rollocks, as ir your idea of two dies stuck together like a quad core CPU.

Neither are current rumours just something you've either completely misunderstood or are just talking crap.

The "rumour" if real is that GK110 is a dual gpu gk104, it is the successor to NOTHING because there wasn't an equivilent card before, it WOULD be a successor to a dual gpu 560ti(actually there is one but not an official Nvidia one, just a daft EVGA one iirc).

The GK112 as rumoured is the successor to the 580gtx, the biggest single core gpu, it has nothing to do with a 590gtx except for performance.

Is the 7970 the successor to the 6990, no the 7990 will be.

We'll see, of the several "sources" of info for a March launch, well, there isn't any, one guy on a forum saying they might launch on Feb, with no source.



http://www.chiphell.com/thread-346223-1-1.html

That is the post these rumours are based on today, look at all the stories, that through to the entire range will launch at the same time in March or April, off that.......... lol.

When was the last time AMD or Nvidia released the ENTIRE line up in the same month, exactly, when was the last time Nvidia or AMD launched a dual gpu card first.........

Is there a huge reason the GK100 can't come out at the same time as the GK104, not really.

Even worse is, comparing the performance to a 7970 means almost nothing right now.

If AMD release a 7975 tomorrow, with default clocks of 1150Mhz, will it be a tweak, a respin or a new core, no, it will be a 7970 with a higher default clock. The 7970 is underclocked to not break a predefined TDP(and one of the biggest mistakes AMD has made in years), it is a 300-350W beast that IS 70-100% faster than the 6970 depending on the game and very very good.

Nvidia's best hope is to come very very close to 7970 performance(real performance) with a similarly sized core, the chance of Nvidia going from largely uncompetitive in performance/mm2 to AMD for 4 years to beating them, in one generation seems optimistic at best, foolish at worst.


Expect an ARCHITECTURE Launch in March/April, gk107, and GK 104 hopefully not too long after, but could be delayed anywhere from there to June really.

Actually he's probably right. At any rate, his is the more reasonable assumption by some measure. If they're naming one of their cores GK110 = GK104x2 then the most reasonable assumption is that it's similar to a dual core processor. From reading this, the most reasonable conclusion I can draw is that they etched two GK104s on the same piece of silicon (on-chip) or it may be on-die, with some dedicated interfacing circuitry. Or (a less likely possibility is that) they may have a better thread scheduler in Kepler that allows them to simply double the GPU and have the scheduler take over from there, in which case it would function like a single monolithic GPU in many respects. (We don't have any info on Kepler's architecture, so who knows.) The thing that seems problematic to this second assumption is the stated 384bitx2 wide memory interface, as that suggests it would work closer to normal SLI. But if two GK104s are on-chip/on-die it may still function similarly to SLI, albeit potentially more powerful as there is no distance between both processors over a PCB or a traditional SLI interconnect.

IF it were any other way, including the way you're suggesting then they wouldn't be naming this a GK110. They'd simply release it as a dual GK104 part, but they're not doing that.

All of this is predicated on the rumour slide being true, of course.

Assuming both these are completely true (which is probably not the case),. here's what I think (and this is pure speculation):

GTX 790 – GK110 = GK104 x 2 - Dual GPU card with top performance
GTR 785 – GK 112 - Super-High end Single GPU card with a price premium to match, and no dual GPU issues.
GTX 780 – GK104 Full - High-end
GTX 770 – GK104 with 1-2 clusters locked
GTX 760 – GK106 Mid-range with slightly above GTX 580 performance

Thank you xsistor, at least someone gets my point

As for drunkenmaster's statement about my suggetion that the original Core 2 Quad core CPUs were actually two dual cores in one chip....

http://en.wikipedia.org/wiki/Intel_Core_2

Core 2 is a brand encompassing a range of Intel's consumer 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module.

...(in the nicest possible way) bite me

 

[xsistor]

if there is any truth to this chart (and I'm not saying there is) it shows 785 beating 790 which could only be explained by dual GPU vs single GPU coupled with SLI scaling that's less than perfect. The 500 series benches show poor SLI scaling in this game (looking at 570, 580 and 590)

 

[Rofflay]

Well i actually hope u are right Xsistor.If the 785 GTR is indeed the full 512bit ring bus single GPU GK 112 then it kicks some serious ass... AND I WANT ONE

PS

What does the R stand for is? Is a typo or is there some hidden reason as to why its GTR and not GTX?
