[SA]Did Nvidia have to spin their 28nm GPU shrinks?

Did Nvidia (NASDAQ:NVDA) have to do a spin on their shrink of GF11x from 40nm to 28nm? It sure looks that way, and there is where the troubling bits begin.

Meh, while not an unbelievable hunch, its a jump to conclusions.

The big problem for Nvidia is that the first batch of 28nm parts isn’t a new design, it is a shrink of the GF11x parts currently on sale. There should be no logic changes to it this late in the game unless something is really screwed up, something we really doubt happened. That leaves the dreaded problem of indeterminate problems with a new process.
This is assumed. Doesn't have to be really screwed up for them to decide to make changes. Die shrinks are straight forward processes, but if nVidia learned anything, they have real competition now from ATI/AMD. They need to be competitive and simple die shrinks are not going to be upping performance huge amounts. Power draw reduction, absolutely, but there is nothing stating that they are not actually revising their plans to increase performance. Or even decrease performance to distinguish the models coming out.

Would they not do that before the die shrink?

Let it be another gtx 480 for all we care... With good coolers, even gtx 580s cooler performs great wrt gtx 480s heat pipes, it will be enough. As long as we have some great performance and overclocking from the cards, we are A OK.

We aren't OK if AMD decides to unleash their 7970s with XDR2 VRAM. That's a game changer.

Unless we see die shrunk 500 series with at least 250MHz bump in stock clocks I don't see this going very well. I'd love to have a 1GHz stock clocked 580 @ 28nm with an awesome vapor chamber design.

I'm still hoping these are all intricate lies spun by Nvidia to cover up Kepler advancements.

It depends. If they already have engineering samples of 28nm and realize its not enough yield, or whatnot, then tweaks will begin. We know its not anything dramatic but minor revisions are allowed. This scenario is far more than likely, but it would be still be my assumption till release.

The fact that they screwed something up is their (SA) conclusion which I think its a leap / stab at nVidia. Concerning their architecture plans and based of the performance per watt roadmap of kepler/maxwell etc, something tells me that performance will not be a problem.

The 5xx generation was mightily impressive and could have easily been the 4xx generation had there not be a massive push for market share and releasing GPUs. Call it a mistake or what not, I personally see that even the performance of the 4xx generation was far greater than the 2xx generation. I could anticipate either the same mistake of greater performance at a cost of heat or power usage, or possibly straight to the equivalent 5xx release, and bypassing a similar 4xx release. Either way, transitioning to 28nm has been hard for both sides from everything I have picked up. I would suspect that its not cut and dry die shrinking as anticipated and its more complicated then we would like to believe.

Honestly I could give a **** how hot the card itself gets (as long as its healthy). It's the heat it pumps into my room that bothers me. So please, no more gtx480's.

And yet the NVIDIA GPU's are much better than ATI Counterparts,the 5xx series sold as hotcakes.

The rant from this guys is just getting old.
