It turns out that NVIDIA has been a Crouching Tiger and a Hidden Dragon. While the main eyes were on ATi's upcoming 80nm GPUs, it seems that 80nm G73s are going to be on the loose soon. The first nVidia 80nm chip seems to be coming in mid-September. Codenamed G73-B1, it’s a mainstream product manufactured by TSMC (Fab12), targeting on ATi X1650 family. The new chip has two versions, G73-N-B1 and G73-H-B1. Besides manufacturing process improvement, G73-N-B1 is very similar to the 90nm variant. It’s pin-to-pin compatible and shares the original P345 PCB design. Manufacturers should be able to shift to these new cores quite easily. Another version, G73-H-B1, is designed for the home theater. It features built-in HDMI and HDCP support. G73-B1 will probably be named Geforce 7650.
