Nvidia today launched its first 90-nm GPU, the GeForce 7300 GS, a low-end part sporting full Shader Model 3.0 support. Other specs include 550 MHz core clock, four pixel pipelines, three vertex shader units and 64-bit memory interface. The GeForce 7300 GS also sports TurboCache technology, which means that the 128 MB version will be able to reach 256 MB borrowing capacity from the system memory, while the 256 MB one could go as high as 512 MB.
