NVIDIA's GT300 'Fermi' GPU Architecture Leaked
Theo over at Bright Side of News published some updated information on the upcoming NVIDIA GT300 GPU this morning that is well worth a look. Theo claims that with the GT300 you can expect to see configurations with 1.5 GB, 3.0 GB and 6.0 GB of GDDR5 memory!
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.
- 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
