Chip capacity is another way in which Samsung’s DDR5 will enable technological advances. Samsung’s 10nm-class process and EUV technology permit DDR5 chip units to ultimately double from 16Gb to 32Gb. Doubling chip capacity means that a single module can contain beyond 512GB. These 512GB modules can fluidly handle huge simultaneous workloads. This will allow for improved scalability in datacenters and reduced footprint across all applications.
30% More Energy Efficient
Finally, DDR5 achieves 30% better power efficiency than DDR4. Many of the attributes that make DDR5 faster also lead to an increase in energy efficiency. For instance, DDR5 increases burst length to about double that of DDR4, improving both command/address and data bus efficiency. In addition, DDR5 doubles the number of bank groups, thus improving overall system efficiency by allowing more pages to be open at any given time. DDR5’s on-DIMM PMIC further boosts power management efficiency. Taken together, these factors make DDR5 not just faster but also more energy efficient and cost effective. For example, replacing a data center’s DDR4 with DDR5 will save up to 1TWh of electricity annually.
DDR5 represents a major opportunity for businesses and organizations in diverse sectors looking to increase computational power, improve scalability, and reduce both costs and power consumption. While DDR5 might not improve our intuition, it will unlock the power of the next generation of processors and allow us to handle the demands of information technology as it continues on the path of exponential growth predicted by Kurzweil.
