Server Description
A balanced general-purpose instance featuring AMD EPYC processors, 64 GB DDR4 RAM, and a bundled 600 GB local NVMe SSD.
Amazon Web Services m5ad.4xlarge is a general-purpose instance featuring 16 dedicated vCPUs and 8 physical cores powered by an AMD EPYC 7571 processor running at 2.2 GHz. It is configured with 64.0 GB of DDR4 memory and a bundled 600 GB NVMe SSD local instance store, operating on the AWS Nitro hypervisor with a 5 Gbps baseline network speed. Performance benchmarks reveal a distinct tradeoff: single-core CPU execution and uncached memory bandwidth are weak, ranking in the bottom 10% to 25%, whereas multi-core CPU metrics, Passmark database operations, and Redis SET operations achieve average tier results. This hardware profile is qualitatively cost-efficient for multi-threaded applications and moderate database workloads that benefit from local NVMe scratch space but do not require high single-threaded compute performance.
