What needs explanation? Nvidia being surprised of RV770's 800 SPs? No way. People working on the field for over 15 years for sure know about pads and the limitations they yield for small chips. So no, they were aware that 480 SPs core would be padlimited if using 256-bit bus, they had to expect more.Quote:

They did overprice their GPUs to milk. The only thing which probably surprised was AMD's aggressive pricing. Not the RV770 chip itself. I remind, they have people working there who have been designing the GPU architectures for some 15 years, if not more. I refuse to believe that random chaps on forums could come up with better guesses/explanations than those people with their expertise.
Specs of upcoming GPUs are frozen typically a year if not more before they are even announced.Quote:

The September 10th event seemed to mainly showcase Eyefinity and the new technologies available with the 5xxx series, not so much the cards themselves. This is normal marketing procedure and the timeline makes sense - showcase some really cool techonology, let the buzz build and many news outlets report on it, let it reach all streams (especially mainstream consumers), then have the products available in (less than) two weeks. Because enthusiasts like ourselves obsess over it and knew all information practically as soon as it left AMD's mouths doesn't mean there's anything wrong with AMD. The leaks and all of that are NOT what's supposed to happen - that's NOT part of the marketing plan and is an example of people jumping the gun before AMD is ready. These last two weeks are vital for dotting i's and crossing t's to make sure the launch goes smoothly. Now of course, if AMD doesn't release by the end of September then I'll agree - they really missed the peak of the buzz and a good launch.Quote:

I'm certain it is compared to when things are going at their capacity. Also the number reserved for 40nm wafers also will include all 40 nm chips, not just the 58XX series. I'm pretty certain that the availability will be greater than the 4770, though. I can recall an article saying the 4770's run was extremely limited and short in duration.
Jen Hsun Huang categorically stated that RV770 took NVIDIA by surprise.Quote:

Where has this been stated? I find it hard to believe, Jen Hsun himself being an EE and has been working with chip architectures, I find it hard to believe that they would have been surprised. Maybe they did not expect the 800 SPs core, but clearly they knew it was possibility. And knew it was the reality way sooner than anyone ever speculated about it on these forums.Quote:

We underestimated the price performance of our competitor’s most recent GPU, which led us to mis-position our fall lineup. The first step of our response was to reset our price to reflect competitive realities. Our action put us again in a strong competitive position but we took hard hits with respect to our overall GPU ASPs and ultimately to our gross margins. The price action was particularly difficult since we are just ramping 55-nanometer and the weak market resulted in taking longer than expected to work through our 65-nanometer inventory.
I am fairly sure that engineers at Nvidia were able to predict the performance of 800 SP chip well enough, so that they could price their cards accordingly. Yhey decided to milk. Of course they did not want to admit it though.
Seeing as how RV870 has had final silicon in production since about June/July, they are obviously going to have MORE units available than RV740. Not to mention the fact that RV740 also had a mobile bin. Let's not forget that TSMC actually shut-down 40nm production for a week or two to try and fix the problems.Quote:

Nope, their underestimation of RV770's "price/performance" translates into their gross underestimation of it, as there's not much left of it to "estimate correctly". Price/Performance estimation requires you to know 1. performance, 2. price.Quote:

In all reality, we will see what happens in the months after launch. Maybe things will change and maybe they won't. Until that time, nothing is certain.Quote:

And for the record, the HD 4770 was never meant to be a limited production production card. It was just hampered by some serious yield issues on the part of TSMC coupled with high demand.
As I said, we will have to see what ends up happening. Beyond that, I can't comment without giving away sources.Quote:

Nvidia might not have expected this to happen at first, but for sure knew about this way before than anyone was speculating this on forums.Quote:

Great way to exaggerate. I was talking about Nvidias chip architects and engineers having a clue about what RV770 might be, what rumours might be true, what to expect from it etc., not about the companies itself. You really seem to want to take this as NVIDIA vs ATI arguing, in that case nothing can come out from this. Thanks, I'm out.Quote:

Uh, first of all, maybe instead of throwing out terms such as pad limited, you should realize that 480 would not have been for the RV770. Seeing as how they were on the same 55nm as RV670 which also had a 256-bit memory but *gasp* 320 SP's.... how in the world would 480SP's be pad limited?Quote:

a) Know exactly what their opposition is going to do
or
b) Know how that opposition will perform
If that were true, then R300 vs. NV30 never would have been a surprise
I can't remember the exact reason behind the pad limit then, if it wasn't the too small die. There was a review or an article about it, and RV770 was supposed to have 480 SPs, but was pad limited so they had "free space" to fill up and slapped 800 SPs to it. GDDR5 uses more pins which caused the bigger die to be pad limited, as far as I can recall.Quote:

That is true , just because you an expert even for 15 or 30 years , Does not give you the power to predict or know about everything .
I mean look at what happened to the Unsinkable ship .
And you have to always remember there is always some one that knows more and better ways to make something than you even if you have been in the business for more than 20 + years . Granted he could also not know what you know .
And I could be wrong but since Nvidia has been top dog and they are all humans , as we are all humans, we tend to underestimate or overestimate our knowledge and skills .
Aside of all of this , man they need to give us some real benchies and such .
: (
Uh you're the one hypothesizing, completely, and pretending to know things "for sure" :rolleyes:Quote:
