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.

rennyathe one I was going to buy on the 24 was from ncix.com but shipping and handling was gonna be a bit too much. The fact that they had the cards on the launch date, 23 goes to show how a big liar silicondoc is. Plus his link on fudzilla, just like I said before, betrays him since it does not say that the model being shown is a working model. I can say I'm making a remote that can trump all other remotes on performance levels and will be the next big thing for gadget lovers. But if I come up with a supposed model and just flash it around, it doesnt mean that it's a working model unless I can prove that it is by using it. So until Nvidia shows the card at work and gives us numbers based on such task then we can talk about it. Hey don't forget that we also go for bang for buck, reason why I got the 5870. I have a feeling that when GT300 does launch, it will be big but also would like to see how ATI responds to that.

rennyaI think we all get it. This guy is mentally ill. So I posted those links to refute his argument and he hasn't touched any. He knows he's lying and that his fudzilla link betrays him. So he'll keep on ranting. silicondoc has to remember this, all big companies that have a working model of an upcoming product do a demo and show the figures and they don't just give you paper work (which is what Nvidia is doing right now.) And it doesn't take a genius to see that GT300 w/e they wanna call it is not even close to be released unless you would want to call many sources such as tgdaily, the inquirer (http://www.theinquirer.net/inquirer/news/1052025/g...">http://www.theinquirer.net/inquirer/news/1052025/g... and ofcourse anand big liers then go ahead silicondoc..So until it comes out ( be it Nov, Mid Oct or Jan) then we can come back and talk performance. Have fun silicondoc and when GT300 performance trumps HD5870 then I'll sell 5870 for Gt300 card but don't forget we also need to see how much power that monster will be drawing. I call it monster because so far the on "paper" performance puts it that way

by the way sorry I forgot to pass you the link where I got mine.. here you go http://www.canadacomputers.com/index.php?do=ShowPr...">http://www.canadacomputers.com/index.ph...=pd&... and here is another site they have had them in stock since the 23rd of sept just like predicted. Man you are full of shit..was gonna buy mine from there but decided to save the money on shipping and boom 3 days later it was in a store right next door.wwohoo..I just said bye bye to my nvidia card and if you wanna know it was yes you guessed it GTX 285 and glad I got almost full value for that!!siyabongazulu - Friday, October 2, 2009 - link
Here SD..And that's where I got mine you dumb prick.. now stop fussin and if you ask when I got it, well so just you know it was on the 29th you idiot and that is simply because I'm in Canada. So if Nvidia had it launched, wouldn't it be somewhere on the web now. by the way here is an article that refutes your claim that Radeon HD 5870 was a fud (http://www.engadget.com/2009/09/24/4-000-alienware...">http://www.engadget.com/2009/09/24/4-00...-benchma... Dell had it already. Here is another (http://www.engadget.com/2009/09/23/maingear-cyberp...">http://www.engadget.com/2009/09/23/main...-desktop.... And all of those pc makers had the cards prior to launch date. So I don't know how you can argue that. So if you Nvidia was to have its card as you claim by using fudzilla pictures, then please provide us with a link that shows any manufacture that is already selling a pc with your GT300 and here is another link that shows how dumb you are http://www.engadget.com/2009/09/23/ati-radeon-hd-5...">http://www.engadget.com/2009/09/23/ati-...o-the-sc... hope that helpsTA152H - Wednesday, September 30, 2009 - link
I agree, it shows sooooo much intelligence and class to curse! It's so creative! It's so wonderful! It's a real shame we don't have more foul mouths in positions of power, because it's just so entertaining!Yay!

I'm with you. Oh wait, don't forget the bold to make sure no one misses it!TA152H - Thursday, October 1, 2009 - link
Admin: You've overstayed your welcome, goodbye.I am beginning to think this site is lost. One thing I always liked about Anand was his tone was never harsh, even if I didn't agree with the content.
Now he's cursing. Yes, and as you said, in bold. Ugggh.
This and their idiotic pictorials of motherboards, then the clear bias towards Lynnfield. Again, I'm not complaining they liked it, so much as the way they lied about the numbers, and it took a lot of complaints to show the Bloomfied was faster. They were trying to hide that.
Their unscientific testing is also gotten to the point of absurdity.
I like their web page layout, but it's getting to the point where this site is become much less useful for information.
It's easy to get to the point where you do what people say they want. Yes, the jerks like to see curses, and think it's cool. I'm sure they got page reads from the idiotic pictorials of motherboards. Most of the people here did want to be lied to about Lynnfield, since it was something more people could afford compared to Bloomfield. It's tempting, but, ultimately, it's a mistake.
I'd like to see them do something that requires intelligence, and a bit more daring. Pit one writer (not Gary, he's too easy to beat) against another. Have, point and counterpoint articles. Let's say Anand is pro-Lynnfield, or pro-ATI card, or whatever. Then they use Jarrod to argue the points against it, or for the other card. Now, maybe Anand isn't so pro this item, or Jarrod isn't against it. Nonetheless, each could argue (anyone can argue and make points, because nothing in this world is absolutely good or bad, except for maybe pizza), and in doing so bring up the complexity of parts, rather than making people post about the mistakes they make and then have them show the complexity.
You think Anand would have put up those overblown remarks in his initial article on Lynnfield if he knew Jarrod would jump on him for it? I'd be more careful if I were writing it, so would he. I think the back and forth would be fun for them, and at the same time, would make them think and bring out things their articles never even approach.
It's better than us having to post about their inaccuracies and flaws in testing. It would be more entertaining too. And, people can argue, without disliking each other. Argument is healthy, and is a sign of active minds. Blind obedience is best relegated to dogs, or women :P. OK, I'm glad my other half doesn't read these things, or I'd get slapped.

Don't let the door hit you in the ego on the way out.the zorro - Wednesday, September 30, 2009 - link
this is a catastrophe.really, nvidia is finished.
this means four or five months of amd ruling.
seriously nvidia has nothing, nothing,zero, nada,
kaput nvidia is over.

Huh? Is that really all the troll you could muster for this article? SiliconDoc has you beat by a mile.
