      Server Description

      A balanced x86 general-purpose instance offering 48 vCPUs and 192 GB RAM for multi-threaded enterprise workloads and database operations.

      General Purpose

      Amazon Web Services m5.12xlarge is a general-purpose instance built on the Nitro hypervisor, featuring an Intel Xeon 8259CL processor with 48 vCPUs (24 physical cores) running at 3.1 GHz and 192.0 GB of DDR4 memory. Lacking local storage and GPUs, it relies on network-attached storage and offers a baseline network bandwidth of 12 Gbps. Benchmark data indicates average multi-core CPU and memory performance, though single-core execution speeds are relatively weak. The instance delivers stable, mid-tier throughput for database operations, Redis SET tasks, and static web serving. Qualitatively, it provides a balanced resource-to-cost profile for workloads requiring high core counts and memory capacity without specialized hardware. It is best suited for multi-threaded application servers, software compilation, and general-purpose enterprise workloads.

      Workload Profiles

      1.67Score
      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.
