AMD Cayman info (or rumor)

[zerazax]

I don't see how a delay has to mean AMD is not confident in their product. There are so many factors that can cause a delay. And think about it, what exactly can AMD do with another 2 weeks? The GPU is what it is, they can crank up the clocks somewhat, but that's about it. However Cayman turns out, it is what is is, two weeks is not going to change that. The only thing that could possibly give a large performance boost is currently drivers are broken or have some kind of show stopper problem that is hobbling performance.

Exactly right. A 2 or 3 week delay isn't going to do much in the grand scheme of things - the silicon is ready, and cards are supposed to be in production.

The most likely answers are drivers, finalizing clocks, or delayed components in the final product.

All this talk of redesigning etc. isn't just flawed logic... its serious-delusional-fanboy-level logic

It's too early to say it for sure, but it seams to be the case.

If that news holds true, then AMD will probabley go for "stunning value for money" solution, which the resent Geforce GTX 570 comes soon seams to be comfirming the same point too. nVidia seams to be preparing to drop the GTX570 on it.

I've been speculating about these delays, as a possiable indication of performance-trouble in AMD-camp. It seams to be getting more clear now, but we have to wait and see he final reult to make sure.

This makes zero logical sense. First, you brought up the GTX 580 as a surprise in performance for AMD earlier in this thread and in other threads, and now you bring up the 570

So lets take a look at these facts:

1) Everyone knew the GTX 480 was supposed to have 512 SP's and higher clocks. These specs were leaked a year earlier, but Nvidia obviously had trouble and couldn't do it

2) AMD projects where their competitors are, so it should be no surprise that 5970 is close to the 580, as that's where they thought Nvidia's highest competitor's performance would be

3) Why would AMD release their flagship 2nd gen DX11 card (which they labeled it as such in the analyst day PR) with inferior performance to a card they thought was supposed to be released a year ago this month?

So please, keep talking about how AMD has performance troubles. They've already ruled out the issue that its yields, and from Dave Baumann's post over at Beyond3D it looks like changing clocks isn't the issue either.

And based on Occam's Razor, the most likely scenario is a simple one:

However, the issue is not yields or such, but just too low availability of one specific driver-MOSFET from Texas Instruments, which is "so new there's no info about it available, not even from TI"
HD6800 uses the same, and apparently there just isn't enough of them at the moment

But please, go ahead and entertain us all with your grand conspiracy theories and "educated" guesses based on such credible sites like FudZilla and Kitguru, the shining examples of journalism

Hmm delayed a month. We can be pretty sure its not yeild or anything major, if it were we would have heard of it before.

It is most likely delayed because of the 580...... amd didnt see that one coming. So my personal feeling is atm cayman and 580 are really close with possibly cayman being a tad slower, amd want fastest single gpu title back so maybe they will up the clocks a bit, go at the drivers hard and deliver the fastest single gpu card a month from now.

The flaw with that premise is... why would AMD not know where the 580's performance would be? Keep in mind that Nvidia was supposed to releasing a 512 SP higher clocked Fermi a year ago this month....

So tell me why AMD would release their 2nd-generation DX11 card with a performance target lower than where their competitor was supposed to be a year ago?

Neither company has ever shot their next generation's flagship at a target lower than where their competitor was supposed to be from the last generation. And if all the architectural changes are to be believed, Cayman isn't meant to be a simple refresh / stop-gap
