    Server Description

    An arm64 storage-optimized platform combining dedicated Graviton cores, high-capacity local NVMe SSDs, and top-tier memory bandwidth for database workloads.

    Storage & DatabaseMemory OptimizedGeneral Purpose

    Amazon Web Services i8g.4xlarge is an arm64 storage-optimized instance powered by a 16-core AWS Graviton Neoverse-V2 processor running at 2.8 GHz. It features 128.0 GB of RAM, 3750 GB of bundled local NVMe SSD storage, and a baseline network bandwidth of 9 Gbps. Operating on the Nitro hypervisor, the instance delivers strong memory performance, with uncached large-block memory read bandwidth of 296.95 GB/sec and a top-tier Passmark memory score. Database operations and multi-threaded decompression benchmarks also rank in the top 25%. While CPU-based machine learning inference is a performance bottleneck, the server's high-capacity local storage and strong memory throughput offer excellent qualitative cost efficiency for data-intensive applications. It is highly suited for database hosting, caching layers, and high-throughput storage workloads.

    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.
