I never said otherwise, so I am not sure why you are bringing this up.

Yes and no. On the one hand, in bandwidth limited scenarios, the extra ROPs are not really useful. On the other hand, you are rarely bandwidth limited 100% of the time in actual games. Furthermore, the ROPs in Fermi are tied to memory channels. While Fermi could have used only 24 ROPs instead of 48, it is likely that the additional die space was negligible.

Then you were not completely bandwidth limited, so more ROPs would actual benefit you there.

Now, 9750 / 12.3 = 792 frames per seconds with 3 monitors and 9750 / 24.6 = 396 frames per second with 6 2560x1600 monitors. Thus, I would guess that whatever the bottleneck is, it probably isn't the ROPs.


Anyway, I've made my point here. If you are sincerely interested in the truth of the matter you can simply carry out the aforementioned test at your own leisure. Goodbye.

I know that it's still a truckload of fillrate no matter what, but it isn't enough for the theoretical maximums that the chips are rated for, in terms of available memory bandwith, and the Fps calculations you made aren't quite right, since there's this little thing called triple buffering, so there's 2 extra frames already stored in memory ahead of the one that's being displayed on the LCD that very moment, so cut that by 3.


Then add antialiasing when each frame has 12 megapixels across 3 screens to begin with, and let's go with SSAA( super sampling AA), to force the GPU's to render at a higher internal resolution than the display resolution, and really push them to their limits fillrate wise.


Yes, i like to torture hardware, and i enjoy finding the breaking point...For instance, let's try the heaven benchmark at 7880*1440, and at up to 2X antialiasing, it can still play back normally, though the FPS figures are pretty low thru the entire benchmark(20~30 FPS).


Jack it up to 4X AA(and it's the MSAA variety to boot, not SSAA), and it displays a new frame every 30 secs....Nope, 3 water cooled GTX580's can no longer handle it anymore.

Ahaha... Looks like Nvidia has to spread false rumors about kepler to try and derail the 7900 sales. LOL. So the $299 price is fake, and who knows what else is fake now. Maybe Kepler doesn't even exist yet.. O_O

Several media are a variety of domestic Kepler low prices, HD7900 will follow the diving like the article, take a look at the foreign media, who did not even reported, along with some media editors forum explosive in the major so-called "material "It is clear that a variety of moves NV's marketing activities in the water behind the army to suppress the HD7900 as well as leading the sales momentum, CHH to see these posts I will lock posts, I hope the members can self-load.

There's probably no kepler, you should convince all your friends to buy 7970s Roadie!

Why would I want to convince anyone to buy a 7970? People should choose what they like.

I figured you'd post some immature reply to it.

My 4 cards just arrived earlier today, so now i'm just waiting for the EK water block's, parallel link and adapters...


Whatever Kepler turns out to be and whenever it gets released and however it's priced, enjoy the wait, i'll be playing with these cards in the meantime...

I would have considered the 7970s if they were not a side-grade. For the same reason 6970 owners largely didn't buy 580s, 580 owners largely won't be buying 7970s.

So by that logic, those that already bought HD7970's won't buy high end keplers since it'll also be a side grade right, since they won't be that much faster anyhow, just like the GTX580 wasn't that much faster than the HD6970....

To give you an idea of what i'm aiming for looks wise, it'll be something like this:





This one is a quad GTX580 setup using EK gear....

That's at least two weeks old.
