      Server Description

      A balanced general-purpose instance featuring dedicated AMD EPYC cores and high memory capacity for multi-threaded workloads and database operations.

      General Purpose

      Amazon Web Services m5a.12xlarge is an x86_64 general-purpose server instance powered by an AMD EPYC 7571 processor with 48 vCPUs, 24 physical cores, and 192.0 GB of DDR4 memory. Operating on the Nitro hypervisor, it provides a baseline network bandwidth of 10 Gbps but lacks local storage and GPU accelerators. Benchmark data reveals a distinct performance tradeoff: single-core performance, including Geekbench and stress-ng single-core tests, ranks in the bottom 10%, whereas multi-core performance, memory bandwidth, and database operations fall into the average middle 50% tier. Notably, CPU encryption performance is strong, placing in the top 25%. Given its high resource density and qualitative cost-efficiency profile, the m5a.12xlarge is suited for multi-threaded workloads such as static web serving, software compilation, and database operations that leverage its balanced vCPU-to-RAM ratio without requiring high single-core execution speeds.

      Workload Profiles

      1.15Score
      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.
