Rhea-AI Summary

Micron Technology, Inc. (Nasdaq: MU) announces the availability of DDR5 memory for data centers validated for AMD EPYC™ 9004 Series processors. The combination provides up to two times memory bandwidth and performance improvements for HPC workloads. Benchmarks show a peak memory bandwidth of 378 GB/s, doubling the previous 189 GB/s. Micron emphasizes its role in the DDR5 transition and partnerships with AMD for enhanced memory performance in AI and HPC sectors.

Positive

• Achieved up to two times memory bandwidth for select workloads.
• Validated DDR5 memory significantly enhances AMD EPYC 9004 performance.
• Drives improved performance in HPC workloads like OpenFOAM, WRF, and CP2K.

Negative

• None.

The combination scales up to 2X the performance for select HPC memory-bound workloads

BOISE, Idaho, Nov. 10, 2022 (GLOBE NEWSWIRE) -- Micron Technology, Inc., (Nasdaq: MU) today announced availability of DDR5 memory for the data center that is validated for the new AMD EPYC™ 9004 Series processors. As modern servers pack more processing cores into CPUs, the memory bandwidth per CPU core has been decreasing. Micron DDR5 alleviates this bottleneck by providing higher bandwidth compared to previous generations, enabling increased reliability and scaling. The combination of 4^th Gen AMD EPYC processors and Micron DDR5 delivers up to two times memory bandwidth on the STREAM benchmark and up to two times performance improvement on select HPC workloads such as computational fluid dynamics (OpenFOAM), Weather Research and Forecasting (WRF) modeling and CP2K molecular dynamics.

“Micron continues to lead the industry transition to DDR5,” said Raj Hazra, senior vice president and general manager of Micron’s Compute and Networking Business Unit. “Algorithms that are increasingly memory-bound need far greater memory performance and reliability to extract insights from huge volumes of data. DDR5 provides the next significant advancement in system memory capabilities required to enable these algorithms, thereby continuing to advance the value of next generation data center infrastructure.”

“4^th Gen AMD EPYC processors continue to raise the bar for workload performance in the modern data center while simultaneously delivering exceptional energy efficiency. 4^th Gen AMD EPYC processors will transform our customers’ data center operations by accelerating time to value, driving lower total cost of ownership, and helping enterprises to address their sustainability goals,” said Ram Peddibhotla, corporate vice president, EPYC product management, AMD.

Micron compared the performance of the STREAM benchmark on a single 4^th Gen AMD EPYC processor system populated with Micron DDR5 at 4800 MT/s to a 3^rd Gen AMD EPYC processor system and Micron DDR4 at 3200 MT/s. With the 4^th Gen AMD EPYC processor system, Micron achieved a peak memory bandwidth of 378 GB/s per socket compared to 189 GB/s with 3^rd Gen AMD EPYC processor system. This resulted in a two times increase in system memory bandwidth.

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

“The continued growth of modeling & simulation, and machine learning workloads in HPC and AI means that our customers are demanding memory solutions that maximize effective bandwidth. Our collaboration with Micron throughout the development and validation phase, with these performance-intensive workloads in mind, allows us to deliver next-generation platforms with a new era in memory performance accelerated by DDR5,” said Scott Tease, vice president of HPC & AI, Lenovo Infrastructure Solutions Group.

Micron has played a pivotal role in JEDEC’s creation of DDR5 memory specifications and was one of the first to sample DDR5 to customers. Micron’s Technology Enablement Program (TEP), the first of its kind in the industry, gave system designers early access to key internal resources to assist their DDR5 validation and qualification processes. Micron is committed to partnering across the ecosystem and will continue to invest in our leadership technology and product roadmaps.
