How do we know what they will be doing to the rest of the architecture?Quote:

By getting rid of one shader in an group that goes mostly unused and spreading the remaining functionality between the other shaders they can increase utilization. That could result in better performance/watt to not have some mostly idle units.Quote:

Whew, didn't mean to rile people up with my response, but usually most reviews I've seen show a 25+% gap between 5870 and 480 @ 2560x1600 (which is the only resolution I really watch nowadays and have for awhile), ESPECIALLY in crossfire/sli modes with two cards it's even wider. I could be wrong, and if I am misremembering the reviews, just carry on to my next paragraph...
My figures may be off a bit, but if Cayman XT is for argument's sake 10% slower than a 580, I would expect it to be more than 10% off of the 580's price overall (more like 15-17% less) since they need a bigger incentive to settle for less (same goes for if Cayman XT is faster than the 580, of course...). The top card always carries a bigger premium in respect to price/performance, and I expect amd/nvidia will capitalize on that whichever way the pendulum swings here.
P.S. I'm in for 2 of whichever is faster... ;). Frankly I'd love for them to come in nearly even, and spark off some nice price cuts.
Apparently he knows the score, but he doesn't leak on AMD.Quote:

Anyways you will most likely be waiting a bit longer 1-2 months at least for GTX 580 due to paper launch. Of course you can always be an early adopter and get in on the premium price in November.Quote:

I just hope that they will have Cayman Pro at or slightly above GTX480 levels of performance.Quote:

But i digress, perhaps Cayman does suck and nVidia have a pile of GTX 580 in warehouse begging to be released, we'll see.
Interesting point. GTX 580 was kept very secret til less than a month before release, so its also possible they were waiting to release something quickly to stem the tideQuote:

I have the opposite feeling. If they are going to launch it, launch it early, even if they have no quantities to sell. That way the hype of the 6970 is derailed because it can no longer claim fastest GPU crown.Quote:

This release is a pure marketing move. If the 6870 was launched before the gtx 460, the release of the gtx 460 would have been a crazy disappointment.
I think you have to ask yourself? Why would NV release a card that not going to be for sale immediately ahead of it competitor if at the very least it didn't beat it. Their is no logical reason to release it later.
Well, then why didn't Nvidia do so with Fermi v1.0? It works both ways hereQuote:

The only reason NV would release it early is to get positive reviews, otherwise you would just be hyping your competitors up.Quote:

Even with the current edition of the gtx 480, considering what the card is, it was released to early and should have been fixed before it came out.
You could say the gtx 480 has a very beta feel to it and was released too early as quantities were bad and their was some obvious flaws in the chip design(no card should have a hole for cooling).
It can go both ways, like Zerazax suggested & i admitted. :yepp:Quote:

Either way, it doesn't really matter in the end, since the release dates aren't too far off beetween them, as consumer, just wait till the dust clear & prices settle, then pick the one that suit your needs & preferences best. I think we all can agree on that. :)
It wouldn't only have the best light if they had card to sell. By the time the gtx 580 becomes commercially available, if cayman xt is as good as some of you think, the hype would be gone and for naught.Quote:

Didn't hurt them all that much when GTX 280 came out and a week later the 4870 made its $649 tag look like a jokeQuote:

Releasing a completely inferior product that can be used only for marketing at this point in time would be simply pointless.
It would be better to spin and not release a card at all(just say a card is coming, like they did with the gtx 480) to hold back sales of cayman. They can't do this if gf110 is released already and people already know its performance.
Giving performance details when your card is not released yet and your competitors card are out with quantity is like showing your cards at the first turn on poker. Your just giving your competitors the advantage because people will know whether to wait for the cards or not. I think NV has confidence at this point on the performance of gf110 to pull such a movie.
If NV cards is 600 dollars and cayman xt is 500 and faster, NV would have just done AMD a favor. Worse yet, you didn't even sell any cards before the arrival of the cayman xt because you didn't have any. That just sounds like a notoriously dumb marketing move and would just help AMD.
One more thing that has lead me to believe NV is not completely screwed anymore is their stock.
http://www.bloggingstocks.com/2010/1...es-downgrades/
It has been upgraded from neutral to buy by analysts and the stock has risen 20% in the last month too.
If NV was completely screwed, I don't think this would be the case.
you mean as in 3x faster than we need? ^^Quote:

i think the real dealbreaker for both nvidia and ati right now is the lack of killer apps, ie games, plus the high cost of 24"+ displays... if displays were cheaper AND/OR there would be at least 2 kick 4ss games that NEED a highend gpu to be maxed out, highend would actually sell some actual volume and not be a corporate e-peen contest :D

thats 16-17% difference between the 5870 and the 480 on average according to anandtech, which i think chose a very good selection of games...
the 480 has MUCH better min fps than the 5870 and 68xx... but av fps is in no way 25% faster on average, and 25%+ on average, thats just ridiculous man, i wanna see those reviews :D
n-zone? ^^
been waiting for that answer since AprilQuote:

Basically, for Nvidia, it's either release the card and at least make some money, or not release it at all and make no money. It's pretty obvious which choice is the best.
Not releasing the card at all would only hurt share holders. You've already sunk cost into researching the card, and since this card is likely based on the full GF100, it makes no sense not to release it after you've spent all this time trying to fix GF100 to have the full 512 units.Quote:

And who's to say how many GTX 580's Nvidia actually has? The only paper launch rumors out there are from a few sources. In all likelihood, Nvidia has enough to get some buyers, especially the die hard Nvidia fans, and generate buzz. Plus, being a 5xx generation, even if it's just a rebrand, makes money with OEMs and wins points from less knowledgeable shareholders.
And you aren't giving the competitors any advantage if your competitor is tight-lipped about performance. Now, this may well be a repeat of GT200/RV770 - if GTX 580 performance is underwhelming, AMD may push Cayman out (or at least leaks out) earlier, just like RV770 where they saw that the 4850/4870 more than beat its expectations and we saw reviews authorized for release a week before they were supposed to be.
Again, you're assuming Nvidia has none in stock. There's clearly pictures of people with them for reviews, so the card does exist. And pricing it at 600 dollars then lowering it to 400 once Cayman hits, if Cayman is faster, is nothing that Nvidia hasn't done before.Quote:

We ARE talking about the company that rebranded G92 130598130980158 times, the same one who is naming this the 580 when it's looking like its more of a 485... you don't think they'd do something like this?
Stocks hardly mean anything. Everyone bought stock before the release of GTX 280 thinking it was going to be great, and it went downhill. How many investors actually know what the 580 is going to be about? Or what AMD's plans are? Few to begin with. Now how many know both?Quote:

Edit: One last point
Remember those GTX 580 performance slides from Nvidia PR? They're being benched against the GTX 480, the 6870, and the 5870.
Now imagine if the 6970's already out on the market. What does Nvidia PR do if Cayman is significantly better? Can Nvidia still say "fastest GPU on the market?" Of course not, it would be an utter PR disaster, and ultimately hurt your relations with shareholders. Everyone knows those PR slides (starting at 80%) are complete BS, but they please shareholders.
Frankly, the safe thing to do is release this card early, because if you release it late, you run into Fermi 2.0's scenario - late to the game, and possibly underwhelming. Release it early, and at least you can claim you've got the fastest GPU, even if it lasts only 10 days
AMD is trying to balance DP, Tesselation and keeping shaders fed is a priority due to the lack of efficiency on cypress.Quote:

Cayman will be a good balanced card with shader and geometry output.

Now, AMD or rather, Richard Huddy states, well our cards have enough tess (damage control) with image/fps quality.(not true)
A game developer thinks, Gee, tessselation allows me to build a cheaper set of textures, due to less time is needed to create the art assest, but they have to build for people who can run the game, which isnt the case with 4800 series from amd, not with their 5800 series and not their 6800 series.
Maybe the adress this in their 6900 series, but then its a 400+us cash game. For that you can buy both a xbox360 and a ps3 with motion gaming for the family.
Fermi is unbalanced card for the moment, the 580gtx shows how its done and it is still on 40nm, with 28nm they be rocking due to what they have learned from their implementation and yes, they still build big chips.
Faster dosnt allow small.
Its like guys and their e-penis, if its big and powerful they feel really good about themself, if its small and efficient they can fool themselves until they met a girl, who knows big and powerful when she see one.
In the technology you need money and resources, Intel got those in spades so does Nvidia.
AMD is still a low budget company with horrible marketing.
People dont buy that often with wellinformed decisions, they buy from benchmarks and just walking into the store buying a computer.
They buy what they know off and it isnt AMD.
Intel inside, the way it meant to be played with NVidia.
Now, where is AMD in that arena?
Nowhere....
