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.

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

Read the article :D

The line-up is consisted out of high-end consumer part [GeForce], commercial [Quadro] and scientific [Tesla]. You can expect memory sizes from 1.5GB for consumer GeForce 380 to 6GB for commercial Quadro and Tesla parts.

well could be 6 gb for consumer side.... :)
although the price might be pretty high for that wish, but hey say bb to crashes or low memory issues :)
