Yes it probably is different internally, so who knows about performance, but it definitely looks nice :)

Yeah it is 30-40W more than 680, but a 680 is very efficient compared to a 7970.

I bet my 59.3% ASIC 7970 eats about 30-40 more watts than what is listed there.

the following would be nice but not very realistic as the 780 would be too close to the Titan.

gtx780

2496 sp
208 tmu
48 rop
384 bit
3gb vram

gtx770

2496 sp
208 tmu
40 rop
320 bit
2.5gb vram


gtx760ti

1536 sp
128 tmu
32 rop
256 bit
2gb vram

If the specs are crap compared to my 680, I'll skip the 780 and Titan and pick up a 690 for a $1K. Price wise, that is still the best option and looking online, micro-stutter seems vastly reduced compared to previous gens. 2GB of RAM for each GPU seems like the only downside.

Why not go with GTX 680 SLI?

No room in the Storm Enforcer case I have. Essence STX on the bottom, 680 up top, little room in between to breathe. Much simpler single card.

If the 780 is 256 bit, its a definite go for the 690.

that will make the 780 look silly if the 770 can have the same cooler and be able to crank the clocks much higher. even out of the box the 770 will already have much higher clocks if its the 680. and the 680 could already hit well over 1200 mhz in most cases. it just does not add up that they will stick their best cooler thats being used on the Titan onto a mid range chip. I am thinking thats its probably a similar design with smaller heatsink and technically not the exact same.

It's important to keep in mind that if the rumors are true, that would make the GTX 770 the fastest GK104 card. It might be a "mid-range card", but it's still pushing higher speeds than the original GK104 flagship (GTX 680) did. So, I can see why it seems weird, but I think the fact that it's a high-end GK104 unit is why it works.

Why is that weird? Wasn't the GTX 570 straight up faster than the GTX 480 despite being the same Fermi architecture? In fact the GTX 570 had more units disabled than the GTX 480 and was able to make up for it solely in clock speed.

I said that it might seem weird at first that a weaker card would be getting a high-end cooler. Then I mentioned that it really isn't as weird when you consider that the weaker card is actually a faster version of the current top-end GTX 680, and it would end up being the fastest GK104 part (excluding the GTX 690). So, while it isn't the top-end card, if the rumors are true, it would be the most powerful single-GPU GK104 card. Hence... the reason to use a good cooler.

It's also worthwhile to consider that if the cards are coming out soon, that it's definitely going to be 28nm. That means they won't be able to gain any extra thermal headroom simply from a lower process (similar to what Intel does). So, to gain any extra headroom, they would need something to help offset any extra heat.

wow, not much of a performance gain from the 680s..

It might not even be a real refresh, it might be GK104 tuned slightly, or maybe not even that it might just be more mature process node improvements and binning of the DDR5/controller.

With what AMD said and current rumors, it wouldn't be in the market leaders best interest to reinvest in a respin when their competitor isn't.

All this will do is place Titan, and the 780 above the GHz and probably put the 770 on par or slightly above the GHz.

My guess is both are going to skip a real refresh and go for the next node to cut overall generation costs.

Toyota actually probably has the right of it that it is a cooler in the same style as Titan, but not the same internally. Titan is a longer card than 680 and I doubt we are going to see the 770 on a PCB that size. Likely the 780 will use the same PCB and cooler minus the light, but the 770 could very well be the 680 PCB with that cooler style.

It does have the same big fan as Titan though from the looks of things and is no doubt a step up from what is on the 680 right now.

That chart is running Furmark. Both companies artificially cap power usage for Furmark. nVidia more so than AMD.

power_peak.gif

This is the highest peak power draw while gaming (Crysis 2). Far more accurate a measure of what the real world maximum power draw would be. Not trying to say Tahiti is efficient, or Kepler isn't more efficient, just trying to show more realistic figures for all of the cards. TPU's max figures aren't any indication of real world figures.

Exactly. You have to measure performance and power draw at the same time.

I'd use average over peak, the 680 is more efficient than the 7970 while being slightly faster. Compared to the GHz the 680 is slower but it gains in efficiency.

AMD slapped voltage onto cards, presumably with some tweaking, namely undervolting you could probably shorten the difference, maybe even overcome it in some cases. With kepler you don't have that option at all.

Titan is considerably more efficient than the GHz while stepping up a few brackets on performance.

So instead of talking about off topic nonsense related to prior gen GPUs, here's some real gtx 700 news:

GTX 780 will indeed be a 3GB 384 bit card. I presume 6GB will be available later as well. I personally think this is great, because consumers have a choice between an exorbitant 6GB card and a more reasonable 3GB card for single screen users. Very few use surround where 6GB would come in handy, so it turns out the 5GB rumors may be false. Going on, GTX 770 will be a GK104 card, presumably identical or close in performance the existing GTX 680 (I wanna say this is similar to the GTX 480 > 570?). Not quite sure where the 760ti will fall in performance - although press slides indicate that it will be slightly slower than the existing 670.

The real question is whether custom cards and custom PCBs are allowed, it is my hope that they are. But with the direction nvidia has been going (eg full control over the product), i'd say it isn't very likely.

Press slide:

The 780 is portrayed to be between the 770 and titan and 'above' the 770. Maybe that's an indication the price rumors are true ($700-750+). :S

Of course that can be reading to far into it. :D

It would pretty ridiculous for nvidia to price the GTX 780 at 750$ for a 3GB card.

Well it's a fair bet to say that the 780 will be somewhere between $399 and $999, but it's not exactly helpful.

Yeah I don't fully believe it fully myself, just a thought. I hope it's $500. :D
