GTX485 Spotted :)

Really? :S I don't even think it's feasible to expect that, all things considered.
A 7%~ increase in shaders, also it's not really a GTX485, as has already been said.
A similar image was going around on Techpowerup a few months ago, it's just a third party board.

If I'm negative about these things it helps when things turn out to a false dawn, and if I'm wrong I'm pleasantly surprised!
The 470 also has less ROP's, Texture units, lower memory bus and less physical memory.
Not to mention it is also clocked slower 607/1215/3348 vs 700/1401/3696.
Assuming this '485' just has the extra SP's with everything else staying the same it would be safe to assume it would be a maximum of 7% quicker.
I could be getting users mixed up here, but if you're the guy who used to have an ATI sig then wasn't heat and power consumption your main issue with the 480? If so, I reckon you'd be telling every soul on here that it'd be madness not to wait, that is, if you hadn't recently bought a 480.

Nah that was a refresh. The 8800Ultra was the top end speed binned 8800GTX with a heavy overclock. This 485 looks like the premium speed binned 480 with out any of its cores disabled.
The 8800 Ultra was an A3 revision G80 and also had better memory. Clocked like a beast, 722/1800/2300, on air.

IF it blows past 300W(real wattage, not their "our 480gtx does 250W, no really, it does" rubbish) then they've not really got much reason to limit clocks to keep within the 300W bracket, I can imagine it beingmaybe 750Mhz, 775Mhz might be pushing it, its not coming close to a 5970 though, and it will be a close call on if the 6870 will trump it on its own, no one knows how much more speed they'd get out of it.
Much like Nvidia, AMD might simply gain a bit of speed if their new design ups ROPS/TMU's vs shaders as it still seems a touch overkill on shaders and lacking in ROP power, as theres so little difference between the 5850/5870.
You've got a little leeway to go bigger, but not much, some room for more effective direction of what they want in the core, and potentially some small efficiency increases from reworked, and more efficient individual parts. IF it gains 40%, Nvidia's boned, 20-30% and it will be ahead in some games, behind in others, I don't much mind to be honest.
For the vast majority of people who have bought 5870/5850's the best upgrade in pure performance and probably value will likely be a 2nd card for xfire as 5850/5870 prices drop.
The 5850 is currently better value than the 460gtx, its faster to a higher degree than its more expensive, if the 6870/50 pushes a 5850 down towards £150-160, a 5870 at £190 6850 at £220 and 6870 at £300-350 then Nvidia will again be back in the position of nothing effective at any price point.
Nvidia would likely make a loss on every 460gtx 1gb at £150-160, they'll price a 480gtx 512sp at £450-550(right now) but likely be forced to around £300-350 on 6870 launch. Still think the 480gtx 512 will be a limited edition, even if its not marketed as such.
I think the 485 has a good chance of coming close to the 5970 seeing as a well overclocked 480 can, I'd guess that a 485 at 750-775MHz will equal a stock 5970

Nvidia are going to find it hard to knock AMD of their perch as manufacturer of the fastest video card in the world they need about 25% additional performance over a GTX480 and only have 50 watts to play with before they break the ATX spec.
In all honesty a GTX485 is just going to be a direct replacement over a GTX480 with it's purpose of giving Nvidia best single card clear daylight in performance between it and the HD5870 to justify it's price tag.

I know what it was.
What I meant is that the ultra wasn't just a speed-binned GTX, it was a respin, A2 to A3. So a different revision core to the GTX.

Nvidia do have the fastest SINGLE card GPU. That's all we really count. A single GPU is never really going to beat two GPUs together. So your comments means nothing really. They aren't going to try and make a 485 beat a 5970. It's pointless, as it most likely cannot be done!

Nvidia and AMD have 300 watts to work with, how they get the most out of those 300 watts is up to them so it doesn't matter how many GPU's you use 1,2,3,4,5,100 it's about the overall result and that's what counts. So yes Nvidia do have the fastest single GPU but don't have the fastest single video card and that's what counts and that where the premium and high profit margin is for these companies.
