Codenamed lasso, AMD's external graphics solution will use the external PCI-e connection announced last week. This solution is targeted at both desktops and laptops, but obviously will make the biggest difference in the latter. Laptops are not known for their high powered graphical solutions, but with an external unit, you may be able to enjoy high quality, portable graphics without sacrificing battery life when on the go. A crossfire implementation is also said to be in the works. It is not yet known whether these devices will utilize a seperate power supply, but I'd say it's a safe bet.
