ATI made another big announcement at Computex, a new external video card platform for notebook computers called the ATI XGP (External Graphics Platform). The ATI XGP is an external PCI Express 2.0 graphics device.
ATI says that the device is externally powered and externally cooled so it won’t place demands on the notebook. Bandwidth in both directions is reported to be 4 Gbytes/s; ATI says that other external graphics solutions were limited in bandwidth.
The XGP platform is optimized to work with the new AMD Puma notebook platforms. Initially according to ATI, the XGP will use Radeon HD 3800 series graphics cards and the first units will utilize the Radeon HD 3870.
When using the XGP with a notebook featuring integrated ATI graphics, CrossFireX is available to enhance performance further. The ATI XGP also provides additional USB 2.0 connectivity for attaching other USB devices like Blu-ray players and more.
This technology allows users to choose notebooks with slim, lightweight and elegant designs, yet enjoy the full performance of a traditional desktop gaming rig wherever it’s convenient.
A specially designed PCIe 2.0 self-attaching cable connects the XGP to the notebook. The cable is designed by Japan Aviation Electronics Industry, Limited. The graphics muscle from the HD 3870 should allow users to buy a lower performance notebook including ultra portable units and then attach the ATI XGP for gaming. The XGP also allows the attachment of multiple displays as well.
