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.

Here in SE Asia, 5870 GPU is available in abundance in retail channels. If you PayPal me USD450, I can go straight to any of the computer shops I passed when I go to work, so that I can buy the card (and a casing that will fit the full length card), then I can take pictures and show it to you.Stop it with the claims that the 5870 launch is just a paper launch. That patently isn't true, and will only make you look stupid.

I'm sure your email box is overflowing with requests, and I'm sure your walk to work will serve all the customers around the world.Thanks for that great bit of information for those walking to work with you in SE asia, I bet they're really happy.

Maybe you should get a Reseller ID, and make that millionaire dream of yours come true, and soon when rooster central flaps it up again, you can prove to the world dry as a bone ain't rice paper.

No, one cannot really fathom the insanity, and red rooster doesn't describe the thickness of skull properly at all, merely the size of it's contents.

Nope, my inbox is not overflowing with requests, because after all, anyone who wants a 5870 GPU, will be able to get it.If you cannot prove that 5870 is a paper launch, maybe you should shut up your shop?

If we are "red roosters" what does that make you? The green grizzly?SiliconDoc - Thursday, October 1, 2009 - link
Actually the first person to offer any thought on the matter suggested green goblin, which was a decent attempt, since grizzly bears aren't green, and goblins have a much better chance of being so.Howver, if you'd the actual nvidia equivalence of what you ati red roosters are, I'd be happy to provide some examples for you, which I have not done as of yet, and of course you're all too stupid rah-rah to even fathom that. That's pretty sad, and only confirms the problem. I'm certain you can't understand, so don't bother yourself.

What sort of rooster are we talking? I mean, a Sussex rooster is almost exclusively not red. Can I be that one, please?Now THAT's trolling.

If you even believed your own pile of fud, you'd go to page 2 I believe it is in the article and see where anand says " sorry that's all we know about the GT300 the game card, nvidia won't tell us anymore"What he was told is IT'S FASTER THAN 5870, and the cores have already been cut, and the cards already under test.
So we already know, if we aren't a raging red doofus, and of course, that is very difficult for almost everyone here.
Also, this was not an official launch date for NVidia, they never declared it as such, just Anand delcared it in his article.
The official launch date for GT300 already spoken about multiple times by the aithors of this website is !!! > THE RELEASE DATE OF WINDOWS 7...
Now, wether nvidia changes their official launch date before then or not, or where the authors got that former information, one can surmise, but changing their AT tune about nvidia in an article title, for a conference and a web video atttendance, in order to appease the shamed and embarrased 3rd time in a row paper launching ati, 4870,4770, 5870, is not "unbiased" nor is it honest, no matter how much you want it to be.
If a person wants to claim it's a planned LEAK to showcase upcoming tech ( nvidia did this AFTER the GT300 gpu cores reported GOOD YIELD) - and combat fools purchasing the epic failure 5870 instead of waiting for the gold, ok.

WOw wow wow!! You sir must be the most ignorant, manipulative, underappreciating, bastard.. sorry for tearing your world but you deserve such credentials and a lot more that can be given to people who display your kind of behaviour.You have been crying bias for no reason at all. If Anand says its paper launch, and if tgdaily says its paper launch (http://www.tgdaily.com/content/view/44157/135/)">http://www.tgdaily.com/content/view/44157/135/) and fudzilla (http://www.fudzilla.com/content/view/15762/1/)">http://www.fudzilla.com/content/view/15762/1/) which seems to be your favourite source so far doesn't even speak of anything but a display model that only confirms that GT300 is under construction.
So the only source you can come up with is yourself and you said it here and I quote "If you even believed your own pile of fud, you'd go to page 2 I believe it is in the article and see where anand says " sorry that's all we know about the GT300 the game card, nvidia won't tell us anymore"
What he was told is IT'S FASTER THAN 5870, and the cores have already been cut, and the cards already under test. " Those are your words, not NVIDIAs, no Anand, not Fudzilla, not from any other reviwers but yours.
Therefore, can you please STFU and stop trying to label everyone a red nosed rooster or whatever the f*** u call them.
P.S Not everyone appreciate your level of stupidity and before you can go and say geez there goes another one, FIY I'm running my system on Nvidia card and will buy ATI and snould NVIDIA "Physically Launch" GT300 and prove it to be better then already launched and benchamrked 5870 then you can come back and start your ranting. Until then plug that sh** hole of yours

Dude, you take this way too personally. Do you have the same burning passion for real problems?
