According to associate the GT300 will be made on 40 nm video chip with about 2,4 billion transistors over the area not more than 495 sq. mm. Let us note that the first revision chip GT200, which was released on 65 nm technology, contained 1,4 billion transistors over 576 sq. mm area. The passage on 55 nm technology allowed GT200 to decrease the chip area to 490 sq. mm.
With comparable sizes GT300 will possess a much denser layout. The quantity of transistors increased by 70%, while the quantity of shader processors grew from 240 to 500 pieces. The memory bus remained as before, 512- bit, but now it works with GDDR5 memory . GT300 Chip promises to support directX 11, its announcement is supposedly planned for the fourth quarter 2009.
AMD Company will also release its version : RV870. Concerning other competitors, Intel company can release larrabee video chip on 45 nm technology, and it will occupy the area of approximately 600 sq. mm. In this case NVIDIA has a certain advantage at the production cost of GT300. Related Products :
