Amazon EC2 R7a Instances

Memory optimized instances powered by 4th generation AMD EPYC processors

Why Amazon EC2 R7a Instances?

Amazon EC2 R7a instances, powered by 4th generation AMD EPYC processors, deliver up to 50% higher performance compared to R6a instances. These instances support AVX-512, VNNI, and bfloat16, which enable support for more workloads, use Double Data Rate 5 (DDR5) memory to enable high-speed access to data in memory, and deliver 2.25x more memory bandwidth compared to R6a instances.

One of the major differences between R7a instances and the previous generations of instances, such as R6a instances, is their vCPU to physical processor core mapping. Every vCPU on a R7a instance is a physical CPU core. This means there is no Simultaneous Multi-Threading (SMT). By contrast, every vCPU on prior generations such as R6a instances is a thread of a CPU core.

R7a instances are SAP-certified and ideal for high performance, memory-intensive workloads, such as SQL and NoSQL databases, distributed web scale in-memory caches, in-memory databases, real-time big data analytics, and Electronic Design Automation (EDA) applications.
