    Server Description

    An arm64 storage-optimized platform featuring dense local NVMe SSD capacity, high memory bandwidth, and dedicated physical processor cores.

    Storage & DatabaseMemory Optimized

    Amazon Web Services i8g.16xlarge is a storage-optimized server featuring 64 dedicated physical cores on the arm64 architecture, powered by AWS Graviton Neoverse-V2 processors running at 2.8 GHz. The instance is configured with 512.0 GB of memory, 15,000 GB of local NVMe SSD storage, and a baseline network bandwidth of 38 Gbps under the Nitro hypervisor. Benchmark evaluations reveal top-tier memory bandwidth, multi-core processing, and database operations, alongside strong software compilation and static web serving throughput. Conversely, single-core performance and small-model text generation represent relative performance tradeoffs, scoring in the average and weak tiers respectively. This resource profile is highly optimized for large-scale database systems, Redis caching layers, and high-throughput web serving workloads that benefit from dense local storage and high memory bandwidth.

    Workload Profiles

    4.8Score
    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.
