Rambus XDR2 to Operate at 8GHz.
XDR2 memory interface is targeting apps that have tremendous memory bandwidth requirements, such as 3D graphics, advanced video imaging, and network routing and switching applications. XDR2 will work at 8GHz and above, which, in case of 16-bit interface provides 16GB/s bandwidth. By contrast, similar GDDR3 memory chip at 1.20GHz can pump up to 2.40GB of data per second. Rambus engineers work closely with chip and system companies to optimize the DRAM controllers to take advantage of the performance benefits that the XDR2 solution provides. The XDR2 memory interface is available for licensing now and could be shipping in products by 2007.
