      Server Description

      A balanced general-purpose server featuring dedicated AMD EPYC processors and DDR4 memory for reliable multi-threaded enterprise workloads.

      General Purpose

      Amazon Web Services m6a.12xlarge is a general-purpose server utilizing the Nitro hypervisor and an AMD EPYC 7R13 processor. Built on the x86_64 architecture, it features 48 vCPUs (24 physical cores) running at 3.6 GHz, paired with 192.0 GB of DDR4 RAM. The instance lacks local storage and GPUs, but provides a 19 Gbps baseline network bandwidth. Benchmarks indicate strong CPU performance, placing in the top 25% for stress-ng and Passmark CPU tests, alongside strong cryptographic and image processing capabilities. Memory bandwidth and database operations perform in the average tier. This balanced resource profile makes the m6a.12xlarge qualitatively cost-efficient for general-purpose enterprise applications, multi-threaded processing, software compilation, and web serving workloads that do not require local NVMe storage.

      Workload Profiles

      1.7Score
      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.
