    Server Description

    An arm64 memory-optimized instance featuring dedicated Graviton cores and high-speed local NVMe storage for demanding database and caching workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r8gd.8xlarge is a memory-optimized, arm64-based server instance powered by 32 dedicated AWS Graviton ARMv9 Neoverse-V2 physical cores running at 2.8 GHz. It is equipped with 256 GB of RAM, 1900 GB of local NVMe SSD storage, and 15 Gbps baseline network bandwidth. Benchmarks show top-tier memory bandwidth, with large-block reads at 405.8 GB/sec, and exceptional database performance, including a top-tier Passmark database score and 68.24 million Redis SET operations per second. While multi-core CPU performance is strong, the instance exhibits weaker performance in LLM text generation tasks. Qualitatively, the custom ARM architecture and bundled high-speed local storage offer excellent cost efficiency for memory-bound and high-I/O workloads. It is highly recommended for relational databases, in-memory caching, and data-intensive applications.

    Workload Profiles

    2.88Score
    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.
