RV380 and RV370
RV380 and RV370 will be very familiar to you. Simply RV360 with native PCI Express interfaces, with RV370 being built on TMSC's 110nm (0.11µm) process and capable of 64-bit memory bus running (like low end 9600 parts currently do), the new chips retain all of the existing characteristics of the parent parts. 4 pixel pipes, two vertex processors, the full compliment of Hyper Z technologies and the same clock speeds (bar the X600 XT part, which is based on 9600XT, getting an official memory clock boost) as before are the defining characteristics.The interface means no power supply connectors needed for either GPU, although none was explicitly required with AGP. The RV380 has been mass produced for a while now and you'll probably have seen it unnamed as a PCI Express validation part, shown off by motherboard vendors looking to show working PCI Express boards at various trade shows.
