Micron DDR5 Reminiscence Now Accessible for 4th Gen AMD EPYC Processors


Micron Know-how has introduced the provision of DDR5 reminiscence for the info heart that’s validated for the brand new AMD EPYC 9004 Collection processors. As fashionable servers pack extra processing cores into CPUs, the reminiscence bandwidth per CPU core has been lowering. Micron DDR5 alleviates this bottleneck by offering larger bandwidth in comparison with earlier generations, enabling elevated reliability and scaling. The mix of 4th Gen AMD EPYC processors and Micron DDR5 delivers as much as two occasions reminiscence bandwidth on the STREAM benchmark and as much as two occasions efficiency enchancment on choose HPC workloads similar to computational fluid dynamics (OpenFOAM), Climate Analysis and Forecasting (WRF) modeling and CP2K moleculardynamics.  

“Micron continues to steer the business transition to DDR5,” stated Raj Hazra, senior vp and basic supervisor of Micron’s Compute and Networking Enterprise Unit. “Extracting insights from big volumes of knowledge requires more and more memory-bound algorithms that want considerably larger reminiscence efficiency with improved reliability. DDR5 supplies the following important development in system reminiscence capabilities required to allow these algorithms, thereby persevering with to advance the worth of subsequent technology information heart infrastructure.”  

“4th Gen AMD EPYC processors proceed to lift the bar for workload efficiency within the fashionable information heart whereas concurrently delivering distinctive vitality effectivity. 4th Gen AMD EPYC processors will rework our clients’ information heart operations by accelerating time to worth, driving decrease whole price of possession, and serving to enterprises to handle their sustainability objectives,” stated Ram Peddibhotla, company vp, EPYC product administration, AMD.  

Micron in contrast the efficiency of the STREAM benchmark on a single 4th Gen AMD EPYC processor system populated with Micron DDR5 at 4800 MT/s to a 3rd Gen AMD EPYC processor system and Micron DDR4 at 3200 MT/s. With the 4th Gen AMD EPYC processor system, Micron achieved a peak reminiscence bandwidth of 378 GB/s per socket in comparison with 189 GB/s with 3rd Gen AMD EPYC processor system. This resulted in a two occasions enhance in system reminiscence bandwidth 

In partnership with AMD, Micron evaluated three HPC workloads (OpenFOAM, WRF and CP2K) on 3rd Gen AMD EPYC processors with Micron DDR4 and 4th Gen AMD EPYC processors with Micron DDR5. The 4th Gen AMD EPYC processor platform with Micron DDR5 improved the efficiency of OpenFOAM by 2.4 occasions, WRF by 2.1 occasions and CP2K by 2.03 occasions.  

“The continued progress of modeling & simulation, and machine studying workloads in HPC and AI implies that our clients are demanding reminiscence options that maximize efficient bandwidth. Our collaboration with Micron all through the event and validation part, with these performance-intensive workloads in thoughts, permits us to ship next-generation platforms with a brand new period in reminiscence efficiency accelerated by DDR5,” stated Scott Tease, vp of HPC & AI, Lenovo Infrastructure Options Group.  

Micron has performed a pivotal function in JEDEC’s creation of DDR5 reminiscence specs and was one of many first to pattern DDR5 to clients. Micron’s Know-how Enablement Program (TEP), the primary of its variety within the business, gave system designers early entry to key inside assets to help their DDR5 validation and qualification processes. Micron is dedicated to partnering throughout the ecosystem and can proceed to put money into our management know-how and product roadmaps.
