In response to bold; the 680 is, right now, right about 31% faster than the 580. Drivers do help older cards but newer cards obviously have much more performance to be milked from them.
The 700 series is a refresh of the Kepler architecture therefore I, too, think anything more than a 20% performance increase over the 680 is being overly optimistic. But as I've mentioned, I would not be surprised if my estimates are wrong. Technology surprises do happen.

yes, but if you actually read the article in the OP and actually THOUGHT about what you would have read instead of just making assumptions based solely on extremely short lived statistical trends about the names of the GPUs that ultimately have nothing to do with the OP...well then you'd realize something going on such as

GTX285 = 1.4B transistors, 240 shaders @ 1368MHz, 80 TMUs, 32 ROPs @ 684MHz, 512bit GDDR3 = 159GB/s

GTX480 = 3B transistors, 480 shaders @ 1400MHz, 60 TMUs / 48 ROPs @ 700MHz, 384bit GDDR5 = 177GB/s (gee, I wonder why this one was so much faster than 285...)

GTX580 = 3B transistors, 512 shaders @ 1544Mhz, 64 TMUs / 48ROPs @ 772MHz, 384bit GDDR5 = 192GB/s (gee, I wonder why this one was only a minor upgrade from the 480)

GTX680 = 3.5B transistors, 1536 @ 1006MHz, 128 TMUs / 32 ROPs @ 1006MHz, 256bit GDDR5 = 192GB/s (upgrade in performance pretty admirable considering the tiny nature of the chip)

now according to this article...

GTX780 = ~5+B (most likely) transistors, 2304 shaders @ 1100+MHz, (192)? TMUs / (48)? ROPs @ 1100+MHz, 384bit GDDR5 = 312GB/s

if this rumor is at all close to being true then there's simply no way the 780 doesn't deliver an easy 40+% performance increase

now if you want to argue that you don't think the rumor is feasible that's fine, and you should state that and give reason why, otherwise your talk of 15-30% is very out of place in this thread, it simply makes 0 sense based on this particular rumor

That's all good and everything, but the GTX 780 is going to be a refresh of Kepler much like how the GTX 580 was a refresh of Fermi, it'll be similar transistor count to GTX 680, or the GK110 transistor count of 7.1 billion at best.

These specs are likely fake unless nVidia is using GK110 with three SMX's disabled, which I doubt. (They have two Tesla's, one with 15 SMX's and one with 14, the numbers in this article are equavalent to 13 SMX's being enabled)

Hitting 1.1Ghz on GK110 is likely impossible on air, too. I could have worded that better.

To be honest, it is because of nVidia's stance on locked voltages that has me a whole lot of not really caring about "What might be" about their 7xx series card.

Now if they said they weren't going to do that, or maybe even voltage lock it, but show some real world demo's that it is REALLY 50% faster, I might get "excited", but the combination of their stance on voltage locks and no real proof the the 50% claim has me going "Meh, what ever. Wake me up with someone actually has one in their hands and can post real numbers."

Hehe, yeah, it was just the "at best" that had me confused biggrin.gif I'm inclined to agree with you, as much as I would love some kind of "zomg awesome" GPU for the kepler refresh, I can't see it happening.

Even if they voltage lock the 7xx series, it will only be a matter of time before someone brings out a hardware mod or modded bios to up the voltage. And EVGA and the like will probably still release upper-market boards with custom PCB and VRMs for us to use.

I still don't think we're going to see anything interesting from NV until Maxwell though. Although it might depend on what AMD release for the 8xxx series, if they blow the water out of the 680 NV might be forced to pull something out of their ass.

My current card is able to run Dark Souls in power saving mode. (P8, P5 always smooth) So I wonder what for would you need GTX 780. It's not like there are that many graphics demanding games.

all I hope is for the new card to be good a compete (ie max and maya etc) and in gaming like the 580 is. If it like the 680 then I dont care.

120hz monitor + SGSSAA = almost any recent game is demanding

^^ This. Not to mention for users who say single GTX 670s/ 680s or 7950s/7970s are overkill. Let them play Metro 2033 with everything maxed out at 1080p. I am sure they will change their minds ...
Dark Souls is a very weak measure of the capability of cards since this game is very undemanding, even my spare GTX 470 can get 60 fps almost all the time in it.
My GTX 670 wasn't able to max out Metro 2033 at playable fps, nor Crysis 1 (have to play without mods to make it playable at Very High 4x AA) otherwise the mods would kill it.
And Skyrim with ENBseries mods feel too choppy sometimes dropping to low 30s or 40s in places with so many trees/plants.

I will probably change my whole setup with the arrival of HD8000 or GTX 700 series of cards... so bring it on Nvidia thumb.gif .
