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.

To be certified or not to be certified?: DEBATE

With uncertainty in job market and with no "definite word" from campus recruiters students are bit worried but have started exploring possible ways forward. One of the paths they wish to explore is earning some certification such as SAP,DB2, CCNE to name the few. In this context, we have initiated a debate and consider the following questions.
  • Should one go for certification at all ?
  • If so when, while he/she is still a student or after graduation?
  • Which certification to be considered ?
SAP
DB2
CCNE etc
