Designed by SAPPHIRE, the new HD 4850 X2 comprises two complete HD 4850 graphics systems on a single PCI-Express card connected by an on-board PCI Express Gen 2 bridge chip. Each GPU has 800 stream process units and a 256-bit memory interface driving 1GB of GDDR3 memory, making a total of 2GB on-board memory. Four Dual Link DVI outputs are provided as well as TV-Out. This provides a choice of Multi-monitor operation or CrossFire mode in which 3D applications such as games use both on-board GPU’s together to deliver a single accelerated output on the Primary display with industry leading levels of performance.
