    Server Description

    An ARM64 storage-optimized instance featuring massive local NVMe SSD capacity and dedicated cores for database and high-throughput workloads.

    Storage & DatabaseGeneral Purpose

    Amazon Web Services im4gn.8xlarge is a storage-optimized instance utilizing the AWS Nitro hypervisor and 32 dedicated ARM64 Neoverse-N1 physical cores running at 2.5 GHz. It features 128.0 GB of RAM and a substantial 15,000 GB local NVMe SSD storage array, alongside a 50 Gbps baseline network bandwidth. Performance benchmarks show average multi-core capabilities, with a stress-ng multi-core score of 48,576.94 and a Passmark database score of 20,399.25, though single-threaded performance is weak, as seen in its Geekbench single-core score of 941.0. This instance delivers high qualitative cost efficiency for storage-intensive deployments by bundling massive local NVMe capacity with power-efficient ARM processors. It is highly suited for database operations, Redis caching, static web serving, and multi-threaded data processing workloads.

    Workload Profiles

    1.5Score
    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.
