    Server Description

    An arm64 storage-optimized instance featuring massive local NVMe SSD capacity, high memory bandwidth, and dedicated physical cores for database workloads.

    Storage & DatabaseMemory OptimizedCompute Optimized

    Amazon Web Services i8g.12xlarge is an arm64 storage-optimized server utilizing the AWS Nitro hypervisor. It features 48 dedicated physical cores powered by AWS Graviton Neoverse-V2 processors running at 2.8 GHz, paired with 384.0 GB of memory and 11250 GB of local NVMe SSD storage. The instance delivers top-tier performance in database operations, memory bandwidth, and software compilation, alongside strong multi-core capabilities. However, single-core CPU performance and small-model LLM text generation remain in the average and weak tiers, respectively. With a baseline network bandwidth of 28 Gbps and high resource density, this server is designed for high-throughput database systems, large-scale web serving, and storage-intensive enterprise workloads.

    Workload Profiles

    3.97Score
    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.
