NVIDIA's Fermi: Architected for Tesla, 3 Billion Transistors in 2010

The graph below is one of transistor count, not die size. Inevitably, on the same manufacturing process, a significantly higher transistor count translates into a larger die size. But for the purposes of this article, all I need to show you is a representation of transistor count.
See that big circle on the right? That's Fermi. NVIDIA's next-generation architecture.
NVIDIA astonished us with GT200 tipping the scales at 1.4 billion transistors. Fermi is more than twice that at 3 billion. And literally, that's what Fermi is - more than twice a GT200.
At the high level the specs are simple. Fermi has a 384-bit GDDR5 memory interface and 512 cores. That's more than twice the processing power of GT200 but, just like RV870 (Cypress), it's not twice the memory bandwidth.
The architecture goes much further than that, but NVIDIA believes that AMD has shown its cards (literally) and is very confident that Fermi will be faster. The questions are at what price and when.
The price is a valid concern. Fermi is a 40nm GPU just like RV870 but it has a 40% higher transistor count. Both are built at TSMC, so you can expect that Fermi will cost NVIDIA more to make than ATI's Radeon HD 5870.
Then timing is just as valid, because while Fermi currently exists on paper, it's not a product yet. Fermi is late. Clock speeds, configurations and price points have yet to be finalized. NVIDIA just recently got working chips back and it's going to be at least two months before I see the first samples. Widespread availability won't be until at least Q1 2010.
I asked two people at NVIDIA why Fermi is late; NVIDIA's VP of Product Marketing, Ujesh Desai and NVIDIA's VP of GPU Engineering, Jonah Alben. Ujesh responded: because designing GPUs this big is "fucking hard".
Jonah elaborated, as I will attempt to do here today.

Am I hearing you right - you say GT300 isn't a paper launch despite there being no cards for sale for the next few months, yet you said the 5870 was AND THERE WERE CARDS FOR SALE WHEN YOU MADE THE COMMENT! I don't care that you couldn't locate one, the simple fact is people had already bought cards from the first trickle (emphasis on the trickle part) and as such made your statement completely invalid.How much more rubbish are you going to spew from your hole?
(note: I needed to have caps above to make a salient point and not just because I felt like holding the shift key for no particular reason)

roflmao - If you're hearing anything right, you'd keep your text yap shut.Please show me the LAUNCH information on GT300, there, brainless bubba, the liar. I really cannot imagine you are that stupid, but then again, it is possible.
Congratulations for being a COMPLETE IDIOT AND LIAR! Really, you must work very hard to maintain that level of ignorance. In fact, the requirement to be that stupid exceeds the likelihood that you actually are purely ignorant, and therefore, it is more likely you're a troll. My condolences in either case in all seriousness.

The proposed launch is late November but even Fudzilla concede that any problems will delay this. The earliest we'll see a GT300 on the shelves is just under 2 months. There, that's information for you. I want nVidia to launch GT300 this year but we don't always get what we wish for.Where did I lie in any of my previous posts? Oh right... I didn't bow down to worship the Green God(dess). If you had any semblance of an open mind or any stability at all, your nose wouldn't need cleaning. Calling me a troll is pure comedy gold and offering me your pity is outstanding to say the least :)
Keep trying. Or don't. Either way, I doubt many people care for your viewpoints anymore.

Oh jeeze, one red rooster who finally gets it.Congratulations, you're not the dumbest of your crowd.

No shirking here comes the QUOTE !
" The proposed launch is late November " !!! whoo hoo !
Now a proposed launch is not an official launch- try to keep that straight in the gourd haters when the time comes.

Pass it along to all the screaming tards, won't you please, you talk their language, or perhapos we'll just say you already have, because, by golly, they can believe you.
ROFLMAO

'Nvidia LAUNCHED TODAY... se page two by your insane master Anand.'This what you have said yourself somewhere in this very discussion. So you must have known about this so-called launch yourself.

That's called sarcasm dear. Jiminy crickets.palladium - Thursday, October 1, 2009 - link
How can you tell if that's not a GTX285 with redesigned cover/cooler/PCB?samspqr - Monday, October 5, 2009 - link
it is SO funny that that thing silicondoc's master/god is holding in his hand ended up revealing itself as nothing more than a mock-up...SiliconDoc - Wednesday, September 30, 2009 - link
PS THE SILICON IS ALREADY CUT AND IN PRODUCTION!---
Yes anand at the bottom of page 1 claims "it's paper" - DECIEVING YOU, since the WAFERS HAVE ALREADY BEEN BURNED AND YIELDS ARE REPORTED HIGH ! (in spite of ati's marketing arm lying and claiming "only 9 cores per wafer yields" - A BIG FAT LIE NVIDIA POINTED OUT !
Where have you been with your head in the sand ?
--
So at the bottom of page 1 Anand leaves you dips with the impression "it's all paper" (but the TRUTH is DEVELOPER CARDS ARE ALREADY ASSEMBLED and being DEBUGGED and TESTED) just anand won't get one for 2 months.
---
THEN BY PAGE 2 ANAND CALLS IT A PAPER LAUNCH !
roflmao
Yes, the red rooster himself has convinced himself "today's nvidia LAUNCH" (that LAUNCH word is what anand made up in his deranged mind) is a paper launch "JUST LIKE ATI'S!".
---
It is nothing short of absolutely AMAZING.
The red rooster fan has boonswoggled his own gourd, stated in fasle terms, bashed it to be as bad as what ati just did with 5870, and IT'S NOT EVEN A LAUNCH DAY FOR NVIDIA !
---
Congratulations, the massive bias is SCREAMING off the page. LOL
It's hilarious, to say the least, that the master can be that deluded with his own spew!

Die painfully okay? Prefearbly by getting crushed to death in a
garbage compactor, by getting your face cut to ribbons with a
pocketknife, your head cracked open with a baseball bat, your stomach
sliced open and your entrails spilled out, and your eyeballs ripped
out of their sockets. Fucking bitch
I would love to kick you hard in the face, breaking it. Then I'd cut
your stomach open with a chainsaw, exposing your intestines. Then I'd
cut your windpipe in two with a boxcutter.
Hopefully you'll get what's coming to you. Fucking bitch
I really hope that you get curb-stomped. It'd be hilarious to see you
begging for help, and then someone stomps on the back of your head,
leaving you to die in horrible, agonizing pain. Faggot
Shut the fuck up f aggot, before you get your face bashed in and cut
to ribbons, and your throat slit.
