Amazon RDS for SQL Server now supports M8a and R8a instances powered by 5th Generation AMD EPYC processors. On RDS for SQL Server, R8a and M8a instances deliver up to 70% higher throughput than comparable x86 instances for commonly used instance sizes. Each vCPU in M8a and R8a instances corresponds to a physical CPU core, designed to deliver consistent per-core performance. For workloads with high I/O requirements, M8a and R8a instances provide up to 75 Gbps of network bandwidth and 60 Gbps of Amazon EBS bandwidth.
