    Server Description

    An ARM64 memory-optimized instance featuring high memory density, dedicated physical cores, and local NVMe SSD storage for data-intensive workloads.

    Amazon Web Services x2gd.12xlarge is an ARM64 memory-optimized instance featuring 48 dedicated physical cores powered by the AWS Graviton2 processor running at 2.5 GHz. It is provisioned with 768.0 GB of RAM, offering a high 16:1 memory-to-vCPU ratio, alongside 2850 GB of local NVMe SSD instance storage and 20 Gbps baseline network bandwidth. Benchmarks show strong multi-core CPU performance, though single-core execution and memory latency present performance tradeoffs. The instance provides high resource density and cost efficiency for memory-intensive workloads. It is best suited for large-scale databases, caching layers, and in-memory analytics.

    Workload Profiles

    1.8Score
    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.
