Graphics titan nVidia has announced that its new line of GTX 400 GPUs will be launched on the 26th of March.

nVidia has been tight-lipped about the technical specifications of its new GPUs, which are based on the company's new ‘Fermi' architecture. The only known fact about the forthcoming GPUs is that they will be fully compatible with Microsoft's DirectX 11 3D graphics API. This would put the GTX 400 series in direct competition with ATI's DirectX 11 compatible Radeon HD 5000 series. The Radeon HD 5000 series was released in the second half of 2009.

Rumors suggest that the Fermi-architecture chips will consist of 3-billion transistors and will be manufactured by TSMC using a 40nm fabrication process. The Fermi chip is also said to offer 512 stream processors, while single-chip GeForce cards could be equipped with as much as 1.5GB of GDDR5 memory.

The high-end cards in the new series are expected to carry the GTX 480 and GTX 470 model numbers. A XFX GeForce GTX 480 graphics card has already been listed on American web retailer Sabrepc's website, carrying a list price of US $699. No other specifications were attached to the graphics card's information page.

The GTX 400 series was originally slated to go into full production in November 2009.
