About this tag
The AMD EPYC 9V64H is a custom CPU co-designed by Microsoft and AMD, powering Azure HBv5 virtual machines for memory-bound high-performance computing (HPC). It pairs Zen 4 compute chiplets with on-package HBM3 memory, delivering nearly an order-of-magnitude uplift in sustained streaming memory bandwidth. This design targets workloads such as computational fluid dynamics, weather and climate modeling, and molecular dynamics, making the EPYC 9V64H a key component for cloud HPC scenarios where memory bandwidth is the primary bottleneck.
