Data Center Evolution: DDR5 DIMMs Advance Server Performance cover

Data Center Evolution: DDR5 DIMMs Advance Server Performance

Driven by a confluence of megatrends, global data traffic is increasing at an exponential rate. For example, 5G networks are enabling billions of AI-powered IoT devices untethered from wired networks. Nowhere is the impact of all this growth being felt more intensely than in data centers. Indeed, hyperscale data centers have become the critical hubs of the global data network. DDR5 DRAM will enable the next generation of server systems providing the massive computing power of hyperscale and enterprise data centers. Learn about the benefits of DDR5 memory and the design considerations for implementing DDR5 DIMMs.

High Speed Memory Interface Chipsets Let Server Performance Fly

High Speed Memory Interface Chipsets Let Server Performance Fly

The demands on server performance continue to increase at a tremendous pace. New requirements from large in-memory databases that are powering today’s cloud services and advanced analytics tools are arriving just as the impact of Moore’s Law is starting to slow. One key new opportunity is for high-speed server memory interface chipsets, which enable high-speed memory performance without compromising on memory capacities. Companies looking to optimize their server memory architecture designs, and improve their overall server performance and reliability, should give serious consideration to optimized DDR4 memory interface chipsets, which enhance the performance of server memory modules.
