Yes but I personally think it is somewhat unlikely, at least for the highend GPU.Quote:

I think honestly they are going for bankruptcy, on purpose.
It seems to be a fad these days.
You go bankrupt so you can ask for more money from the bankers.
I got a hint of it looking up the euro crisis, somewhere I heard on the news that amd was talking to certain bankers.
I don't remember where or anything but at the time, I thought they was going towards that direction because of who they were talking to.
I'm betting that they will try to count as to big to fail, being in all the new consoles, and having the rights to x86-64.
I mean really, x86-64, how could you even get a patent for something that is so simple lol.
Eh whatever though ^^.
The next gen of consoles are a joke anyways, I personally wouldn't back those.
But whatever floats your boat.
LordEC911 - blah blah, it is absolute nonsense. On 28nm is impossible to make a bigger chip then Tahiti. it would not be cost-effectiveQuote:

Get real. AMD is not a bank. AMD hasn't most of government on their payroll, the scam can go on without AMD.Quote:

AMD can't afford to make a super high end big chip. They don't have a big enough foothold in the super computing/professional market to make it financially feasible. That being the payoff from such a heavy r and d move and the number of wafers at 20nm these take up, would be wasted unless they sell a lot more professional cards.
With the cash reserves so close to the breaking point, its a move AMD can't afford. AMD will not take the huge monolithic chip route unless they have more guarantees in the professional market. The only way AMD is getting a 60 percent performance increase is through 20nm. It isn't happening at 28nm.
It seems convenient for AMD that these rumors pop up just when the gtx 7xx series is coming out.
I never said they were a bank lol.Quote:

Again I'll repeat myself.
I'm only guessing, I don't know, but this is my guess.
They'll run the company into the ground, and a bank will bail them out.
Increase sales in there professional line lol..
Yeah right, not gonna happen yo.
No one is gonna buy amd for professional use.
They make consumer parts, there professional parts, all though labeled as such they are not that's for sure.
That's where I would say get real lol...
I don't mean no offense dudes, I don't think I'm pissing in the wind either.
Exactly, is Tahiti even 60% faster than Cayman?Quote:

Depending on how well it actually performs in compute tasks, Titan is actually efficient with its size and compute performance. Titan is actually 100 percent faster than a gtx 580(at 2560*1600), which hasn't been said about any flagship over the prior in a while, even with a new architecture, even on a new node. I think the last time this was actually the case was the gtx 8800, because 5870, 6970, gtx 280, gtx 480, gtx 580 don't fullfill that requirement.
And even still AMD needs another 15-25 percent faster card than titan to reach 60 percent faster than tahiti.
I remember you saying similar things about the 6970 over the 5870 and we all know how that turned out.
Well at least you are thinking in the right direction now... though not making the right calculations.Quote:

tech powerup tends to reduce averages(e.g the 7970 originally tested only 10 percent faster than the gtx 580) because of the amount of games they use and older games and even they got 85 percent at the highest resolution. look at the comparison chart between the 4870 vs its predecessorsQuote:

Although the comparison isn't perfect because during the 4870 the only chart there is the combined chart, take the combined chart from titan and the difference between titan and old cards is still alot larger than the 4870s.
If nvidia didn't price titan as it did and it came earlier, it would have been the second coming of the gtx 8800. The more impressive thing about titan is it demolishes similar sized monolithes from last gen. Not tiny cards like the 3870. Basically for the 4870 to do something similar, it would have to double the performance of the gtx 8800. This is from a pure performance point of view(the most impressive thing about the 4870 was the value, the least impressive thing about titan).

This is probably the best time for AMD to gamble big.
Pros:
1) They know the 700 series will be slower than Titan, even with rumours of a Titan ultra on the horizon AMD can predict it's specs and work beyond them
2) They've already got developers on their side due to their work on next gen Consoles, thus games will be optimised more for AMD and they can insure their drivers are good for these games before launch. (A position nvidia used very well)
3) With access to these developers they can release their new cards with nice game bundles that take the sting out of the price.
4) Nvidia are distracted by the mobile market.
5) The fastest card on the block sells, the slower card has to take a price cut.
Cons:
1) Yields: On 20nm it'll be risky to go all out with a huge chip this early, on 28nm it would be crazy to go with what would be GF100 sized monolith. Possible but crazy.
2) Timing: Any delay would allow nvida to react with a chip outside of AMD's plans, the 8970 would have to land early enough so nvidia would effectively stay silent about the 800 series to protect 700 series sales.
3) Drivers: The driver team would have to be spot on, right out of the gates, it took them too long to realise the potential of the 7970.
4) Demand: Titan is selling because people think that the 780GTX will slower, thus they think there won't be a faster card on the market until Maxwell. It's an assuring investment, a super fast but super expensive 8970 will have Maxwell on the Horizon just as the 7970 had the presence of the 680GTX looming behind it.
It's tight, but I think the Pro's outweigh the cons this time around. It's rare to see nvidia unfocused on the GPU market, but to be honest if any company needed to diversify it would be nvidia. Right now the PC market is shrinking, every idiot wants to make a phone, and too many people just do facebook, and twitter. And Nintendo has been outshone by Gungho entertainment with the release of a single mobile game.
Not a bad analysis, however, I would not say that Nvidia is unfocused on GPU Technology or their GPU business. They're full aware that they need to keep it rolling and rolling fast if they're going to maintain the profitability they have. Without professional graphics and gaming graphics, nvidia is a company that loses money.Quote:

Plus, after the disastrous HD 7990 launch, their driver team needs to focus on a number of key issues before they even think about announcing anything.
Personally I think this is damage control time since GK110 is pretty much untouchable right now.
"Already"? If they hope for a 2013 release, the first batch of ES cards would have to be "out of the oven" so to speak a good 4 months ago, if not earlier. For example, NVIDIA had working Kepler cards about a year before the GTX 680 was officially announced.Quote:

As for Maxwell, AMD will either try to get a 6-9 month headstart (unlikely) or hope Nvidia don't do another GK104 with Maxwell, preferably both. I wonder if AMD themselves work on 2 designs this time around.
We will see what happens. There might be something else in the works to compete with Maxwell...Quote:

I think with AMD locking up next generation consoles it forces Nvidia to focus on making GCN's current strengths their own for future generations. Forward+ rendering, for example, is something they very badly to catch up on.Quote:

In the end I don't see a tangible performance advantage or disadvantage for either brand because the hardware needed to run console ports will have the bar set much lower than pc hardware is capable of already today. We already have PC hardware more than capable of handling anything next gen consoles would need to run.
I have not seen a post by anyone on the forums about their 7990, it may be the worst selling high end launch of all time. So I checked at newegg, all out of stock, but only about 20 reviews for all five cards.Quote:

The 7990 seems to truly be The Card That Time Forgot.
You'd think AMD would have lots of these on hand as the chips are 17 months old, but no one has them and no one seems to be buying them the few that exist.
Contrast this with NV's last two $1000 chip launches: Lots of vendors had the cards, product going in and out of stock daily, lots of people on the forums posting about their new cards.
AMD could learn something about timing from this. If they put out a quad 7970 card next year as their high end, people will give it the same reception.
Don't know if they were duped by TSMC on 20nm process availability, but two whole years without new high end parts is disastrous for them. About the only way they'll be selling 7970s at any decent price is if they throw in a FX8350.
amd never needed a card like 7990. my guess is they just launched it for getting attention but if they really thought it will sell well then this means they have a really big problem in their way of thinking.
