      Server Description

      A balanced x86_64 general-purpose instance featuring dedicated AMD EPYC processors and sixty-four gigabytes of memory for diverse workloads.

      General Purpose

      Amazon Web Services m6a.4xlarge is a general-purpose instance featuring an AMD EPYC 7R13 processor with 16 dedicated vCPUs, 8 physical cores, and 64.0 GB of DDR4 memory. Built on the Nitro hypervisor, it delivers a balanced 1:4 vCPU-to-RAM ratio and 6 Gbps baseline network bandwidth, though it lacks local storage and GPU accelerators. Performance benchmarks show strong single-core CPU execution and efficient small-model text generation, balanced by average multi-core and database performance. However, uncached large-block memory bandwidth is a notable bottleneck. This instance is qualitatively cost-effective for general-purpose applications, software compilation, web serving, and moderate database operations that do not require high-speed local storage or extreme memory throughput.

      Workload Profiles

      0.773Score
      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.
