    Server Description

    An ARM64 memory-optimized instance featuring high-density RAM, local NVMe SSD storage, and top-tier memory bandwidth for database workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r8gd.4xlarge is an ARM64 memory-optimized instance featuring 16 dedicated physical cores powered by the AWS Graviton ARMv9 Neoverse-V2 processor. It is equipped with 128.0 GB of RAM, 950 GB of local NVMe SSD storage, and an 8 Gbps baseline network speed. Performance benchmarks highlight a top-tier Passmark memory score and strong large-block memory bandwidth, alongside robust multi-threaded decompression capabilities. Conversely, the instance shows performance limitations in LLM inference tasks. The combination of high memory density, local NVMe storage, and efficient ARM architecture provides qualitative cost efficiency for memory-bound applications. This instance is best suited for database operations, caching layers like Redis, and memory-intensive data processing 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.
