NVIDIA GT300 ''Fermi'' Detailed (http://www.overclockaholics.com/104942/NVIDIA_GT300__Fermi__Detailed.html)
NVIDIA's upcoming flagship graphics processor (http://www.overclockaholics.com/forums/#) is going by a lot of codenames. While some call it the GF100, others GT300 (based on the present nomenclature), what is certain that the NVIDIA has given the architecture (http://www.overclockaholics.com/forums/#) an internal name of "Fermi", after the Italian physicist Enrico Fermi, the inventor of the nuclear reactor. It doesn't come as a surprise, that the codename of the board itself is going to be called "reactor", according to some sources.
Based on information gathered so far about GT300/Fermi, here's what's packed into it:
Transistor count of over 3 billion
Built on the 40 nm TSMC process
512 shader processors (which NVIDIA may refer to as "CUDA cores")
32 cores per core cluster
384-bit GDDR5 memory interface
1 MB L1 cache memory, 768 KB L2 unified cache memory
Up to 6 GB of total memory, 1.5 GB can be expected for the consumer graphics variant
Half Speed (http://www.overclockaholics.com/forums/#) IEEE 754 Double Precision floating point
Native support for execution of C (CUDA), C++, Fortran (http://www.overclockaholics.com/forums/#), support for DirectCompute 11, DirectX 11, OpenGL 3.1, and OpenCL

These are beginning to seem like a nice GPU, hopefully we will not have to bend over to buy one, or 4 like Kal does HAHA

Wait cuda is coded in C? Why don't we have more CUDA apps? We must have more than a few aspiring programmers in the enthusiast arena.

Think 8800Ultra Prices and grab yee ankles. My gosh I can't even fathom paying that out. I'd sooner pick up art paper, coloring pencils and a stop watch. We'll see who renders images first :taunt:

Considering all we have seen about the GT300 has been created with paper and coloring pencils, I would say your chances are pretty good :)

K I am confused now. The thing they were talking about in december of last year was GT300 as the Tesla card.
Considering everything so far has been talking about GPGPU, does this mean there is no GT300 desktop card expected?
also the price point of 900 dollars is probably going to be seriously low. If these are tesla cards I believe they START at a few grand a pop.

Though I dont believe charlie as such, but this time, he seriously has a point, even if its not all true but atleast they dont have a working card still

WHAT DO YOU DO when you have a major conference planned to introduce a card, but you don't have a card? You fake it, and Nvidia did just that

So fanboys were trashing Charlie about his 2% yield article over at OCF. Saying that "it was already proved to be a false statement"
Considering this guy used to write for INQ, I am not going to comment on the guys credibility, one way or the other, but that faked Fermi board is definitely interesting.

This just in, any references to Fermi in the recent Nvidia Press Release by CEO Jack Fruit Hung, are to be disregarded. Apparently, the press misunderstood the CEO's Korean accent. He was not talking about the anticipated "Fermi" launch but actually releasing information in regards to his imaginary friend "Kermi" that helps him count to 30 when brushing his teeth in the morning.
Apparently with the new "Kermi" he is able to fold the number of seconds it takes to brush the bs outa his mouth by half, bringing the total bs washout time down to 15 seconds.
Little is know about how effective the cleaning really is but we do know this CEO loves imaginary things.
That is all, carry on.

Oh that was too funny.
This is the same guy that said "How much faster can you run the Blue Screen of Death" isnt it? (In reference to the nv_______ 8800 series BSOD issues...)

Charlie got me laughing good this time. And yes, I think he touched a sore nail on Nvidias foot this time. I'm keeping an eye on the nvidia site atm to see if they worry enough to issue a statement during the weekend :laughing:
Also ther are some reasonable thoughts by nordicjedi over at 411 (http://www.411overkill.com/forum/phpBB3/viewtopic.php?f=142&t=6340&p=86743#p86741)

Not sure but apparently Nvidia did issue a statement
http://www.fudzilla.com/content/view/15798/34/
Nvidia confirms
Fermi that was running PhysX at Jensen's GTC keynote was real but the one that we all took pictures of was a mock-up.
The real engineering sample card is full of dangling wires. Basically, it looks like an octopus of modules and wires and the top brass at Nvidia didn't want to give that thing to Jensen. This was confirmed today by a top Nvidia VP president class chap, but the same person did confirm that the card is real and that it does exist.
Charlie was surely right about this one here. The card that Jensen showed and we all pictured is not a working sample. Some key people at Nvidia have promised to show us the picture of the real one. Stay tuned.
