The GT300 video chip is a 40 nm GPU with 2,4 billion transistors over the area of 495 sq. mm. The speed level will be determined by the 512 stream processors and 512- bit bus, which is nearby with GDDR5 memory works at the frequency of approximately 4000 MHz QDR.
Yesterday associate report that the GT300 models stepping A1 already exist. At present, NVIDIA reveals possible deficiencies in this chip in order to decide about the release of new stepping or the passage for mass production.
GT300 announcement was originally planned to the fourth quarter 2009, but it can be reported for a later period due to the new stepping or in case of problems with the 40 nm technical process from TSMC company . The video card GT300 models can be shown to a limited circle of persons already in the beginning of June, in the exhibition computex 2009. Related Products :
