Nvidia is expected to launch its 90nm GeForce 7900 graphics processor unit (GPU), in GT and GTX versions, on March 9, according to sources at Taiwan graphics-card makers. In addition to the GeForce 7900 series, Nvidia plans to add the GeForce 7600 (codenamed G73) by the end of next month, the sources indicated.

Nvidia’s upcoming GeForce 7900 GPUs will have more competitive pricing than the Radeon X1900 from ATI Technologies, the sources noted.

ATI launched the Radeon X1900 GPU in January 2006, with the XT version priced at US$549 and the high-end XTX line priced at US$649.
