      Server Description

      A balanced general-purpose virtual server offering thirty-two vCPUs and average multi-core performance for parallelized enterprise workloads.

      General Purpose

      Amazon Web Services m5a.8xlarge is a general-purpose instance powered by an AMD EPYC 7571 processor on the x86_64 architecture. Managed by the Nitro hypervisor, it features 32 vCPUs and 128.0 GB of DDR4 memory, providing a balanced 1:4 vCPU-to-RAM ratio. The instance does not include local storage and delivers an 8 Gbps baseline network bandwidth. Performance benchmarks indicate a significant tradeoff: single-core CPU and single-threaded compression performance are in the bottom 10%, while multi-core CPU, memory bandwidth, and database operations perform in the average middle 50% tier. This resource profile makes the m5a.8xlarge cost-efficient for parallelized workloads such as multi-threaded web serving, Redis operations, and software compilation, whereas it is less suitable for single-thread intensive applications or large-scale language model inference.

      Workload Profiles

      0.844Score
      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.
