nVidia GT300's Fermi architecture unveiled: 512 cores, up to 6GB GDDR5 - Bright Side Of News*
Vidia GT300 chip is a computational beast like you have never seen before. In fact, we would go as far out and state that this is as closest as GPU can be to a CPU in the whole history of graphics technology. Now, time will tell whatever GT300 was the much needed revolution.

GPU specifications
This is the meat part you always want to read fist. So, here it how it goes:
3.0 billion transistors
40nm TSMC
384-bit memory interface
512 shader cores [renamed into CUDA Cores]
32 CUDA cores per Shader Cluster
1MB L1 cache memory [divided into 16KB Cache - Shared Memory]
768KB L2 unified cache memory
Up to 6GB GDDR5 memory
Half Speed IEEE 754 Double Precision

never heard of the source website 'brightsideofnews.com', although i'm seeing the same link/specs propagating all over the net. how reliable is it?

it would be ddr5. And yea 6gb not for consumers its for scientific/tesla cards...desktop cards would expect 1gb, 1.5gb variants or maybe 2gb.
 
To my understanding GT300 might be like GT200 on Steriods.. Those 16 Shader clusters might be 16 TPC up from 10 on GT200, and 32 Cuda cores are SPs up from 24 on GT200.. and this beast might have die size > 500mm^2..:)
 
nvidia will get the performance crown but what important is whether it can get profits......i mean just by the specs it looks that this chip is going to be bigger than its gtx 2xx series.....
 
Just like we disclosed in the first article "nVidia GT300 specifications revealed – it's a cGPU!", nVidia GT300 chip is a computational beast like you have never seen before. In fact, we would go as far out and state that this is as closest as GPU can be to a CPU in the whole history of graphics technology. Now, time will tell whatever GT300 was the much needed revolution.

Beside the regular NV70 and GT300 codenames [codename for the GPU], nVidia's insiders called the GPU architecture - Fermi. Enrico Fermi was an Italian physicist who is credited with the invention of nuclear reactor. That brings us to one of codenames we heard for one of the GT300 board itself - "reactor".

When it comes to boards themselves, you can expect to see configurations with 1.5, 3.0 GB and 6GB of GDDR5 memory, but more on that a little bit later.

BSN is a new site that has recently been launched by Theo Valich. He is ex-Inq. Got pissed off with the Inq's management and a few people there as well (charlie) and decided to branch out on his own.

lol

JUST GOT THIS..

says NV faked the whole fermi thing

SemiAccurate :: Nvidia fakes Fermi boards at GPU Technology Conference

REPS NEEDED :)

SemiAccurate on the other hand, is Charlie's personal website :rofl::rofl:
 
nvidia has confirmed that the card they showed in the pictures was a mockup. but they did have one demo at the conference working on the real fermi card.
