Despite the fact that NVIDIA is frantically seeking out other semiconductor foundries for high-volume manufacturing its 28 nm chip designs, and despite some looming irritants, NVIDIA appears to value its relationship with TSMC highly. NVIDIA's senior vice president for Advanced Technology Group Joe Greco, in a recent company blog post, credited close collaboration with TSMC for the stellar energy-efficiency (performance/Watt) figures NVIDIA's Kepler architecture has been able to achieve.

What a confusing relationship these two companies seem to have.

'love-hate'

on topic, I have always wondered if power leakage improves as the process(in this case 28nm) matures.. in which case 2nd iteration of kepler will have better perf/watt

Maybe the headline should read "We learned from our Fermi mistakes"

...It was published that they (NVDA) didn't do a great job working out the production kinks with TSMC when they slapped Fermi together.

Anyway, good for them, and good for us!

It does, but Ive only seen it make a difference in the final product in the case of CPU steppings - the best examples are the B3 vs C0 Q6600's. With GPUs i have never seen the same series of cards go through two different steppings... i.e. the later versions of the 480s were not substantially better than the earlier, etc.

If the process matures enough to squeeze more power out of the chip, it seems like NV's strategy is to tweak the design and release a new model line. Otherwise the differences seem to be minor.

My 480 I used as a toaster
My 580 was better
My current 7970 is a ice machine in comparison to the Nvidia´s....

Is AMD using TSMC or Global Foundries?

heat and power draw are directly related how hot a chip can get while keeping a cheap/hopefully quiet cooler attached is up to the company.

and a 7970 vs 680 power draw is about the same, meaning they both generate the same amount of heat in a closed area.

The stock 7970 just has a more aggressive fan profile then a 680 so it's cooler under load but generates more noise.

Except the 7970 doesn't performs as well as a 680 so if anything you're producing unnecessary heat when compared to nvidia, that whole performance per watt crap which is really only valid when discussing efficiency rather irrelevant if you're just talking about performance, top dog is top dog.

They produce around the same amount of heat is what i'm getting at for the most part.

also amd's dedicated gpus are produce at TSMC GF is not nearly up to snuff for that work.

When are 680s expected to graduate from paper launch status? This is getting pretty annoying.

Oh yea. Performance/Watt is nVIDIA's new focus now. They are so proud of what they have accomplished with Kepler, they want to continue on that path.

Nobody is perfect, and if anyone is a sports fan, then you know all streaks come to an end. Jensen himself said at the time that (one of) nVIDIA's motto was, "Go big or go home", and I can't help but respect him for that.

NVIDIA got lucky with GK104 and they are making a killing on it.


NVIDIA needs to get on TSMC ass and get some kick ass cheaper mid range cards out ASAP.
