HKEPC have posted up details of an upcoming 80nm GPU from NVIDIA, codenamed G73-B1. Apparently it's due around mid-september as a possible "GeForce 7650" stamped offering to compete with ATI's soon to be X1650 family of cards.
The new chip has two versions, G73-N-B1 and G73-H-B1. Besides manufacturing process improvement, G73-N-B1 hasn't got much changes to the 90nm version. It's pin-to-pin compatible to 90nm version, sharing the original P345 PCB design. Manufacturers are able to shift to new product at the first time. Another version, G73-H-B1, is designed for home theater. It has build-in HDMI and HDCP supported, and hence lower the cost for HTCP graphic solution.
