AMD XGP
AMD XGP (eXternal Graphics Platform) is brand for an external graphics solution for laptops and notebooks by AMD. The technology was announced on June 4, 2008 on Computex 08 trade show, following the announcement of the codenamed Puma notebook platform.

Development
Originally reported by Hexus.net as a side project to the R600 series graphics cards. Codenamed Lasso, the project is an external graphics solution using desktop video cards, and data is sent via two cables as defined in PCI-E external cabling specification (version 1.0). The project would later fall into development hell with unknown development status. In June 2008, near Computex 2008, rumours surfaced over the Internet about AMD is preparing an external graphics solution for notebook computers, but using a proprietary connectivity solution instead. The ATI XGP was officially announced on June 4, 2008 during the course of the Computex 2008 exhibition.
