Although many analyst and observers claim that Nvidia Corp.’s latest code-named GF100 graphics chip, which powers GeForce GTX 400-series graphics cards, cannot be produced in mass quantities due to exceptional complexity, Nvidia itself claims that everything is under control and the company still has opportunity to release a graphics solution with 512 stream processors.

Nvidia gave the first glimpse onto the code-named GF100 chip (NV60, GT300, G300) and Fermi architecture in late September 2009 and with fanfares said that the graphics processing unit (GPU) had 512 stream processors inside. However, in a bid to improve yields of the GeForce GTX 400 product line, Nvidia disabled 32 out of 512 stream processors even on flagship GeForce GTX 480 graphics board. Nevertheless, after the product was formally launched on the 12th of April, it is still rarely available and where it is in stock, it costs much more than its recommended price of $499. Despite of this situation, Nvidia claims that a GPU with 512 stream processors may see the light of the day in the future.

“Nvidia does not comment on unannounced products; however, we have a chance to launch a graphics chip with 512 cores in the future,” said Drew Henry, the general manager of GeForce business at Nvidia, in an interview with DigiTimes web-site.

Nvidia GF100 chip – which powers both GeForce GTX 470 and GTX 480 graphics boards and will eventually power the Tesla C2000-series computing cards – is the most complex GPU to date, it consists of 3.1 billion of transistors and is made using TSMC’s 40nm process technology known for its insufficient yields. According to certain financial analysts, the yields of the GF100/Fermi chips was between 20% and 30%. Nonetheless, Nvidia claims that the yields are much higher.

“TSMC's yields for its 40nm process has met our expectations and market rumors about the yields being lower than 20% are completely untrue. We currently have everything under control,” said Mr. Henry.

Right... Because we've never heard that one before.

even if they manage having 512 sp. what will the power consumption be.

seems the 512sp part would be new silicon, sans GF100 problems.

maybe the rumored GF104 ?

why do you think TDP should rose up? or why do you think it must be a new respun stepping?

it could be more niche than gtx480 part with extremely cherry picked gf100 silicon parts. but somehow i'm in disbelief that will ever happen except that they cancel current gtx480-480 and start gtx480-512 series when they run out of little failing chips just for sake of marketing.

but then again that kind of practice was never seen in top end products just mainstream ones.

maybe will increase more than 300 watt ???

The current 480 sp parts have 1/16th of the shaders disabled and all of the rest of the chip active. Why would and of you think this would consume more then 1/16th more power at most.

The current gtx480 consumes around 250 watts so the 512sp product would consume around 265 watts max which is still bellow the ATX specifications for max power usage by an add in card and lower than the power consumption of a gtx295.

They wouldn't make a new silicon revision for this, but just cherry pick gf100's that all 16 shaders work well on. If they were going to spin new silicon it would most likely be a 1/2 shader version to increase yield and deliver parts to OEM's where most of the money is made in gpu's.

The GTX 480 already eats almost exactly the same power as a GTX 295 according to Xbitlabs, and more according to some other review sites. A GTX 512 will just eat up to 1/16th more power. The 250W TDP is a rather low estimate, even if officially stated by Nvidia. In some games, true consumption goes way higher than 250W.

LOL ... like they'll ever admit critical fail that they still have with current jumbofailure product. it leaks more than rotten wood ships.

btw. it's great thing that everywhere we see praises how complex this wanna-be-gpu-chip is really are. it's just larabee's second incarnation born into life by other designers.

I never thing the GPU now can EAT power Consumption 2 Times than OTHER part of system

Anyone buying a GTX 480 is clearly a nVIDIA fanatic. You have a lot cheaper and better performing solutions from ATi.

Forget eggs I'll upgrade to bacon if I ever got one of these.

They might as well design another pcb to use two 8pin connectors and a all copper cooler with a gold electroplated base.

It is funny that they deny imaginary rumors about the yield being under 20% while infact the rumor was that the yields were between 20% and 30%.

Exactly what i was thinking. Thats proof alone that it must be 20-30% if they only deny <20%. lol

Nvidia is probably basing their comments on the fact that the "bad" chips will be used on future GTX 460 cards (hence the denial of <20% yields).

I hope NVidia kicks Radeon's ass.

Nvidia does not need to kick Radean's ass.
AMD will do it to themselfs with better product release soon.

Everything is under control, eh nVidia? Hmm, here in Canada, there is an extremely low availability of the GTX 480 and 470 parts. Many of them are STILL pre-order and/or just not in stock yet. This is April 28th. The launch was (if you can call it a launch) was April 12th.

Pricing right now is ok, hovering above suggested retail pricing but good luck getting your hands on one.

Furthermore, there are better alternatives from ATi for lower power consumption, lower heat output, and a very good performance/price ratio. And if you want the ultimate in single card performance, partner cards such as the HD 5990 are there.

I wonder how nVidia or its partners will make a dual GPU version of Fermi? I guess not since they can't even get a proper 512 SP part out, a part they have been yelling about since the Fall of 09, bringing outstanding performance.

10-15% increase of performance on average vs the HD 5800s while making your room warmer and louder and making your wallet much more lighter doesn't make a Fermi purchase logical, unless you want raw sing card/single gpu performance (for those who don't want a 5970/5990 for some reason). Or even SLi performance which creams CrossFire in many situations at high resolutions (ATi, might want to get those CrossFire drivers worked on more).

So no, nVidia doesn't have everything under control. Now they have to think about Fermi parts for Quadro, Tesla, AND their mobile segments (laptops). By the time they get their shit together, Southern Islands would be out and Northern Islands already being tested for.
