      Server Description

      A balanced general-purpose virtual machine featuring AMD EPYC processors and dedicated memory for multi-threaded workloads.

      General Purpose

      Amazon Web Services m5a.4xlarge is a general-purpose instance featuring an AMD EPYC 7571 processor with 16 vCPUs, 8 physical cores, and 64.0 GB of DDR4 RAM. Operating on the AWS Nitro hypervisor, it provides a balanced 4.0 GB of memory per core and a baseline network bandwidth of 5 Gbps, with no local storage or GPU accelerators. Benchmark data shows that while single-core performance and single-threaded compression tasks are limited, multi-core execution and memory bandwidth for cached blocks perform at an average level. The instance is qualitatively cost-efficient for workloads requiring balanced resource allocation rather than peak single-thread speed. It is best suited for general-purpose applications, software compilation, Redis caching, and standard database operations.

      Workload Profiles

      0.48Score
      Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
