Still all guess work.
Even that firestrike extreme performance slide that has been doing the rounds looks very much like something a GTX 690 would do with a mild overclock (I did similar the other day).

Yeh if legit that score wasn't impressive. A mildly overclocked Ti or Black would beat it. I doubt there will be any big jumps. Even with 20nm, the gains are now outweighing production costs. Its time for some lateral thinking, or we might be in for a 2 year wait everytime for the high end cards.
I think the way to go is multi GPUs on a single board. There is no reason why you can not put 4 mid range GPUs on the same board with about 3 billion transistors on each one and it should be easy enough to keep cool, you could even scale up by adding extra cards for anything up to 16 way SLI or CF. We can already do 4 way setups so there is no reason why this can not be extended to higher numbers.
Wouldn't it be about bandwidth over anything? As bandwidth increases with memory speed and bus width, increasing one or the other should impact performance at higher resolution. Granted the most beneficial way is to increase the bus width though hence why I suggested they would need some silly fast vram over a 256bit bus

The 290(X) does better at higher resolution in comparison to GK110 due to its increased ROP throughput (64 vs 48 at similar clock speeds). The bandwidth is just one piece of the puzzle. If the bandwidth is the same the actual make up of the memory bus etc won't make a massive difference.
2 or even 3 years currently.
gains be abysmall, like a new cpu.
28nm is just a gapstop for some benefit for those 4K screens people.
gamers overall with a 290/780 wont buy.
I think im out of the PC market for now. Give the horrid ports PC's are getting the £1000's I have spent on PC parts etc over the years and for what? Higher resolution and a few extras on the Graphics.
Given that UBI are now going out of their way to make PC games = to console so not to show up the consoles, and the fact 9 weeks into watch dogs I still suffer horrendous jerks when driving. Steam's ever tighter EULA etc etc, I am about ready to leave to PC and take the easy route on my PS4.
I love my PC, its High End does nothing but play games all optimised but is letdown by the software. There was a time when PC gaming was beyond amazing! But now IMHO its a joke. Look at steam...First 28 games coming soon are all indy or Early Access games. Nothing wrong with indy Early Access but come on give us a AAA game thats not just a port.
Also UBI's new £49.99 for PC games makes me laugh..Ill just buy on PS4 and have no issues. I think PC gaming is being marked for either death or a radical change.
I just can't keep spending on the latest hardware when its either ignored by devs and all I get is a console port or its full of bugs and does not work.
Its all Fail sadly.

It does not seem to work like that when tested for real, wider buses trump high memory speed at high resolution.
You also see the same thing happening with 4 cards and the difference between PCI-E 2.0 and 3.0. In theory there should be enough bandwidth there to run PCI-E 2.0 at 4K but when switched to PCI-E 3.0 the difference in performance can be dramatic.
It don't work like that a GTX 690 has 64 ROPs compared to 48 on a GTX 780ti yet the later card is far superior at high resolution due to using a 384bit bus compared to a couple of 256bit buses.
Shame the reference 290X only comes with 4gb of VRAM.

Videocardz.com seem to be fairly certain on the bus specs. It's looking to be as some rightly describe - the 680 all over again. We're probably looking at a reasonable(ish) price and possibly just a touch faster than a stock 780Ti and Titan Black, whilst not treading on the Titan, quite possibly not only due to the bandwidth but the lesser 4GBvram. If I had to guess, 8Gb variants won't arrive from AIBs until or possibly after Christmas.
8GB 256bit.
If I could photoshop an Audi R8 with a hamster wheel on my phone.

At 1080p the 780ti is around 10% faster than a 290x but at 4k they are around equal. The 780ti has more Bandwidth and a smaller bus. Is this proof of the wider bus benefiting the 290x at higher resolution?

As the 290x has less Bandwidth compared to the 780ti then it must be the Rops on the 290x helping at 4k.

Guess my 7950 cards will have to do for a wee bit longer. I've been hoping all year a card is released with better performance than my crossfire, annoyingly it looks pretty meh for this year. Do love my cards, but really getting excited at the prospect of a super powerful single card solution that gives me more frames than I currently get.
I don't think the 870/880 will be worth while for 780/290 owners but for those of us still on 670's/7950 etc they could very well be a nice step up.
If it really is 3200 cores (780ti 2880cores) then with the enhancements that Maxwell has shown with the 750 vs the 650 it could be a bit of a monster (512 core Maxwell 750 beats a 768 core Kepler 650ti) that's third less cores.
I do agree that at higher resolutions the bus speed will hold it back just like it did with the 680/770, but at 1080p this could be rather decent.

Nothing wrong with the memory bandwidth on a 290X, 1625mhz is not too hard to do.
I don't think you will be seeing many 780ti's with that bandwidth not even EVGA Kingpins.

I refuse to be milked on 28nm anymore ! 
It does work like that when the cards have otherwise similar memory bandwidth....

Yea i was comparing both at stock. I know once memory overclocking comes in the 290x should end up with higher bandwidth.
