The current PCI Express Integrator List states ATI's R520, R520 GL, RV515 XT and RV530 XT for desktops have successfully passed validation procedures. Additionally, the lists also indexes new mobile chips based on the R520 architecture: the M52GL, M54GL, M56 and M58 which are all PCI Express compliant.
According to executives of ATI Technologies, the R520, R520 GL, RV515 are to be made using 90nm process technology at TSMC. The company said during the most-recent conference call that it did not expect to ship its new generation product family for revenue before August, 2005. Given that the chips were production ready by the 25th of July, 2005, when the PCI-SIG Integrators List was last updated, graphics cards makers may receive final VPUs sometime in August. Sources close to add-in-board partners of ATI confirmed this information earlier to X-bit labs.More details at X-bit Labs
