Now that AMD seems to have given the 40 nm Juniper GPU (on which are based the Radeon HD 5700 series models) a new lease of life, manufacturers can continue to get innovative with the Radeon HD 5770 GPU. One such board partner, Yeston, designed a Radeon HD 5770 X2 graphics card, which simply put, is a dual-GPU graphics accelerator that makes use of two Radeon HD 5770 GPUs, each with its own 1 GB of GDDR5 memory, that share the PCI-Express interface using a PLX-made bridge chip (perhaps the same one used on the Radeon HD 5970).
