I dont speak about performance, but as what is the architecture... this is why i was made a comparaison with AMD who have show us GCN architecture in June 2011... Im sure a lot of peoples in server, computing, professional graphism will be interested to know what this new architecture can bring as feature on the table.. ( starting by me for my job... ( well im a DAO, CAO designer Autocad )Quote:

GTX 680 45% Faster (Radeon HD 7970)
Wow, 45% faster is nice, but priced at 649?Quote:

@BHD
And your source is? Not that I don't believe you or anything,but 7970 is ~34% faster than 580GTX in 25x16 with 4xAA/16xAF. In order to be 45% faster than 7970,single GPU 680 needs to perform around 1.93x better than 580GTX which even though is not impossible ,is highly unlikely. You have 2x the "stream" processor count but you have roughly the ~2x less shader clock which is now in sync with the rest of the GPU. You have almost 84% more memory BW though so there is close to enough of it for this to be true. But SPs have to be massively more efficient to net such a huge gain over GF110.

That would be the GTX660Ti, and it looks it will be priced U$S399. Based on what BHD said, if a GTX680 is 45% faster than HD7970, that would mean a GTX660 will be ~5-10% faster.Quote:

That's why a new AMD sku makes sense. Every HD7970 is clocking 1200Mhz easily, thats 30% more clock, that usually translates to 25% more performance. That hypothetical "HD7980" would perform between GTX670 and GTX680. Just what AMD has been doing all these last years...
[/Speculation]
Looks really good. I hope it's true. Still, only 2 GB memory :(
a chip with 1024 SPs would be probably 20% bigger than a 580, and that took a year to come out and why we had the castrated version called a 480
Interesting according to the website GTX660Ti and up all are 550mm2 so that means its the same chip, 7970 is about 365 mm2. GTX660Ti does seem to be the logical fighter for 7950 not 7970 that 10% better than 7950 might be on specific tests. I do expect GTX670 to exceed 7970's performance and GTX680 to destroy 7970 "If the charts on the website are true"
In theory, I don't think it's that unreasonable for it to approach double Fermi performance (Say +80% ) with those spec's (and accompanying huge die size). What I do think would be a problem in reality is thermal headroom. whilst you can double up your shader count from one node to another, it usually accompanies a marked power consumption increase, and even fermi 2 (GTX580) is pushing the boundries of what's acceptable (With the GTX480 clearly demonstrating what's not acceptable)Quote:

I think 60-70% faster would be more realistic expectation, which would still make it considerably faster than the 7970. I don't think AMD would respond with anything wild though of course. They have no interest in pushing limits in die size and power on GPU's.. Their strategy seems to be release something early, and enjoy a comfortable lead for ~6mths, then sit in the sweet spot when Nv finally releases their monster.
A modest successor / refresh to the conservativley clocked 7970 would be enough to maintain them in their previous position for single GPU I think (6970 vs 580, (5870 vs 480) (4870 vs 280) etc
Really hard to believe. Too much information about the entire line up too soon.
We have never known really that much information about a a lineup this early. Especially performance numbers and most importantly, accurate numbers.
Not to mention Nvidia suddenly being ultra-coy about their amazing performance :rolleyes:
I'm impressed if this stuff's true. Still, two months in advance of launch, seems... suspect?
Come on really, if they had this kind of performance they'd show it. Just one official benchmark - they did it with Fermi 4 months before the 480 was released, showing how it pwnd the 5870 in Far Cry 2. Surely they can show how amazing they are in any title right now? Just 1 official benchmark, that's all we ask.
Whatever if this is true or not, the TI version is what the TI version was for the 560TI, a 470 or if you like more a castrated 570-580.. I doubt they want to launch something like that, the 560TI was a card for use bad cores who cant be used on 570-580. other than that, this is a serious waste of money, take a 550mm2 chips cost and laser cut a good part of it..Quote:

GTX 680 45% Faster (Radeon HD 7970) :D But 1000$ price for DUAL GPU :rofl::down:
Seems too good to be true! :p:Quote:

If those specs are true, it looks nice, but again, whats with the low VRAM? Seems like NVIDIA did not learn their lesson from GTX 580.
64 ROPs thats alot
7970 is only 32 ROPs I think AMD needs to up those and not wait 4years like they did going up from 16 rops in the past
