Beyond DDR3

XDR™2 Memory Architecture

The XDR™2 memory architecture is the world's fastest memory system solution capable of providing twice the peak bandwidth per device when compared to a GDDR5-based system. Further, the XDR2 memory architecture delivers this performance at 30% lower power than GDDR5 at equivalent bandwidth.

Designed for scalability, power efficiency and manufacturability, the XDR2 architecture is a complete memory solution ideally suited for high-performance gaming, graphics and multi-core compute applications.

Initial systems can achieve memory bandwidths of over 500GB/s into an SoC. Each XDR DRAM can deliver up to 38.4GB/s of peak bandwidth from a single, 4-byte-wide, 9.6Gbps XDR2 DRAM device, and the XDR2 architecture supports a roadmap to device bandwidths of over 50GB/s.

Capable of data rates of 6.4 to 12.8Gbps, the XDR2 architecture is the latest generation in the award-winning family of XDR products. With backwards compatibility to XDR DRAM, the XDR2 architecture is part of a continuously compatible roadmap, offering a path for both performance upgrades and system cost reductions.
