Finish website plaza.fi has used the clock speeds leaked last week by sweclockers.com (see post) to estimate the performance of the GTX 590.

Maksimi = Max

Keskimaarainen = Average

Minimi = Min

Depending on how much Nvidia down clock the GTX 590 this could be slower then a 6990 by a wide margin and by an even bigger margin due to frame buffer limitations at higher resolutions.

Maybe 650Mhz core speed to match a 6990??
 
I really dont see this being correct, the 580 out performs the 6970, the 6990 is two 6970 and the 590 is two 580. So transitive property would show that the 590 would thus out perform the 6990. I also do not think they would release it with a 600 Mhz core speed.

A down clock is guaranteed as the PCIe slot and 2x 8 pin PCIe power connectors cannot supply enough power for two full speed GTX 580 cores.

You're looking at 375watts max for the GTX 590, for reference SLI GTX 570 requires 400watts to run so the GTX 590 will be quite crippled to keep in line with the power requirements.

You're making a bunch of assumptions there.

Each manufacturer supplies something to the effect of a 2xMolex to 1x8pin adapter. Reason for doing so is not only to makeup for those psus without the connectors, but that 2xMolex can "normally" supply over 100w each.

Many an overclock will fail due to not enough power going down the 8x or 6x pin pcie connector. This isn't 'always' because the "limit" has been breached - some psus just aren't up to it - not even all the 'quality' ones.

There are many great psus out there that will let the pcie connector take as much power as it likes - well, until the wire gets too hot cos it's not thick enough to cope. Others will be either limited or shutdown.

But, hmmmm, manufacturers supply these adapters, even in this day'n'age... I wonder why ?

Those results were clearly compiled by an ATI fan boy. lol

No seriously i beleive the GTX 590 will be much better than the HD 6990
 
I'll wait till I see 100% legit benchmarks on Anandtech and Tom's review before I believe anything.
 
I agree with most that those "predicted" results are utter cr@p.

Look Evga claim the 460 Win2 has better performance than a single gtx 580, that's a massive jump in performance, because as I understood it 2 x 460's in sli was about as good as a single 570. So I think I'd hazard a guess at the 590 being along similar lines and out performing 2 x 580's in Sli, which I'm pretty sure would also outperform the 6990.

But I think my main concerns are how noisey is it? how hot is it? how much juice does it use? and how over priced will it be?
 
Fudzilla is just reporting based on that post linked in the OP

i really wouldnt trust it

IF the 590 preforms worse than a 6990 then it will only be by a couple of frames per second (if that)

and if NV really wants the preformance crown (which they do) then it would make more sense for them to put 2 570 chips at a higher clock speed on one PCB than 2 580s at a slow 600MHz

having said all that PCI-E standard was not followed with the 6990 it can use more than 150w over the maximum so why would NV stick to the PCI-E standard?
 
It's all about the architecture of the chips which could perhaps change. Also how can we be sure that it'd be two 580 chips rather than 570 ones? Also bear in mind scaling on a single PCB would be tonnes better than SLI.

Agreed.

Just look at the 295 when they released it. They put 2 275 gpu's on there, not 2 285's.

Realistically, you'd expect it to destroy the 6990 seeing as the individual gpu's are better, but we'll wait and see if they've had to cut corners or not.

I sincerely hope not.

The performance is going to be very close imo

Though it does seem the clocks will be c. 605-615MHz

We are only going to find out when the card is actually released I guess

Can tell you thats NOT correct. ---- Goes back to playing with his 590's
