    Server Description

    A memory-optimized ARM64 instance featuring high-density system memory and integrated local NVMe SSD storage for database and caching workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r8gd.4xlarge is a memory-optimized server powered by 16 dedicated ARMv9 Neoverse-V2 cores running at 2.8 GHz. It features 128.0 GB of system memory, yielding an 8.0 GB per core ratio, and includes 950 GB of local NVMe SSD storage. Operating on the AWS Nitro hypervisor, the instance delivers a baseline network bandwidth of 8 Gbps. Benchmark results highlight top-tier memory performance and strong database operations, though CPU-bound processing and LLM inference speeds remain average to poor. This hardware profile makes the r8gd.4xlarge highly efficient for memory-intensive workloads, caching layers, and database applications requiring fast local storage, while avoiding the higher costs associated with traditional x86 architectures.

    Workload Profiles

    1.76Score
    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.
