NVIDIA GT 300 October
NVIDIA's GeForce GT 300 video hardware won't show until October at the earliest, a leak of its talks with partners may hint. They tell the Inquirer that the first actual production models will be ready October 15th following a tape out, or a first submission for manufacturing, in June. The new technology would represent the first significant update to NVIDIA's line since the GTX 275, which itself is a minor upgrade of the older GTX 260.
Whether or not NVIDIA will make its target is nonetheless called into question. The company is likely to have the first revision of fully testable silicon on August 1st but may take as much as 3 months after testing to manufacture enough for the first batch, putting an actual release in mid-November at the soonest. Any need to significantly revise the card would likely push the actual release further.
GT 300's feature set hasn't been fully leaked, though it may introduce support for DirectX 11 and newer OpenGL effects and will likely use NVIDIA's version of 40 nanometer manufacturing to improve performance and reduce heat versus today's 55nm parts.
