[VR-Zone] No NVIDIA GeForce GTX 780 before March 2013, Maxwell Only in 2014? - Page 5  

post #41 of 87
from what i read it sounds like there wont be a gf110 for geforce cards, only for tesla. the 700 series will be like the 500 series. minor improvments, same architechure. there wont be a 380bit bus 780... the bigger bus will wait till maxwell.

I think there will be, maybe they will turn off part of the chip (2304SP, 1/6 or 1/12 FP64), and maybe cut ram bus to 320bit (5*64).

Even though I would really like to upgrade my current 6950 we will have console refreshes coming soon and I think I'll wait for Sea Islands at the earliest, new hardware to take advantage of the new games that will come out after the console refresh. Hopefully we will see a new golden age!

I'm not going to change cards until after the new consoles are out.

The GK110 silicon will make for a new series of cards next year, along with a GK104 refresh to take up the "bottom end".
Based on what? GK110 will not only have a 384-bit bus, but the memory controller will be improved.
Expect ~300Gb/s stock and ~350Gb/s over clock... This is I/O bandwidth. Internal bandwidth should be several times higher. And I believe shaders have nothing to do with bandwidth, its the ROPs that matter, and we have no evidence that the ROPs will be limited internally.
It'll be at least 50-70% faster than a GTX 680.
Let's consider:
GK104 is mainly liimited by it's ROPs, the 256-bit memory bus is balanced quite nicely so that it provides enough bandwidth in most cases to feed those 32 ROPs.
GK110 will have 50% more ROPs than GK104.
GK110 will have more than two times the amount of transistors, it's very likely it'll have to deal with a slightly slower clock speed, about 90% compared to the GTX 680 is where I'm thinking.
50% more ROPs at 90% speed will mean an increase in performance by 35%, and that's assuming perfect scaling with more ROPs (the GTX 660 Ti points to Kepler not really scaling that well with more ROPs.)

So the most likely estimate for the GK110 in terms of gaming performance will be in the ballpark of 30-35% faster than the GTX 680. It will, on the other hand, crush 3DMark11 scores as 3DMark11 is the only bench that actually scales well between the GTX 670 and 680 in terms of theoretics.

I thought the GK110 is for tesla cards only?

I think gtx780 will have something like GK114 in it.
Will hav more bandwidth than GK104 may be, but similarly castrated compute performance.
GK110 probably won't make it to gamin hardware. And there's no way tor put 2 of those on 1 board for a feasible gtx790.

I really hope that the 7xx series isn't anything like the 6xx series..

You want the 700-series to not be power-efficient and have great performance?

GK110 is already being tested for professional Tesla use. As far as gaming, there's no word on if the GK110 will be used. It may be the same chip and it may not. Basically I'd expect GK110 based on its specs and size to probably be a good 50% better performance than a GTX680 if the chip is suitable for gaming.

It's worth the wait for me, but I think we might see another level of toaster ovens in our PC's when the GK110 is out...its so huge!
