    Server Description

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

    Memory OptimizedStorage & Database

    Amazon Web Services r6gd.4xlarge is an ARM64 memory-optimized instance featuring 16 dedicated physical cores on an AWS Graviton Neoverse-N1 processor running at 2.5 GHz. It is equipped with 128.0 GB of RAM, a 950 GB local NVMe SSD instance store, and a 5 Gbps baseline network bandwidth. Benchmarks show average multi-core capabilities, with a stress-ng multi-core score of 24282.92 and Redis SET operations reaching 20.4 million operations per second, though single-core performance and LLM inference speeds are weak. The combination of high memory density and local NVMe storage makes this instance qualitatively cost-effective for memory-intensive workloads requiring fast local scratch space, such as database hosting, caching layers, and data processing.

    Workload Profiles

    0.977Score
    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.
