GT300 announcement is going to be in December – NVIDIA head during October will visit TSMC for checking the readiness degree of this video chip for mass deliveries according to several sources.
NVIDIA will simultaneously discuss the prices of 40 nm production , which is released by TSMC. During July the last company was possible to raise the release level of suitable 40 nm chips from 30% to 60%.
GT300 will be the most powerful CUDA chip ever. Based on technicad data about NVIDIA GT300 shader units frequencies, memory speed and other, people fom Hardware-Infos (Germany) have decided, that G300 performance will be 2,4 TFLOPS. It’s more than twice GTX280 cards 0,933 TFLOPS. Comparision is not direct, as G300 supports MIMD architecture, but GTX280 only SIMD. GPU is rumoured to have rather tremendous die area of 452mm², which means that only about 104 – 105 of such dies can fit onto one 300mm wafer.
Nvidia received first working samples from TSMC (Taiwan Semiconductor Manufacturing Company) in the beginning of September.
