    Server Description

    An ARM64 memory-optimized instance featuring dedicated Graviton cores, high-capacity local NVMe SSD storage, and top-tier memory bandwidth for demanding database workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r8gd.8xlarge is a memory-optimized server utilizing 32 dedicated ARM64 physical cores from the AWS Graviton ARMv9 Neoverse-V2 family. Operating at 2.8 GHz, the instance provides 256 GB of RAM, establishing an 8:1 memory-to-core ratio. It includes 1900 GB of local NVMe SSD storage and a 15 Gbps baseline network speed. Benchmark results place its large-block memory read and write bandwidth in the top tier, alongside exceptional database operation performance. While multi-core processing and memory throughput are highly competitive, the server shows weaker performance in certain LLM inference tasks. This hardware profile makes the r8gd.8xlarge highly efficient for memory-intensive databases, Redis deployments, and high-throughput web serving.

    Workload Profiles

    2.9Score
    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.
