    Server Description

    An ARM64 memory-optimized platform featuring dedicated physical cores, high-capacity local NVMe storage, and strong multi-threaded database performance.

    Memory OptimizedStorage & Database

    Amazon Web Services r6gd.16xlarge is an ARM64 memory-optimized instance featuring 64 dedicated physical cores powered by AWS Graviton Neoverse-N1 processors running at 2.5 GHz. It is equipped with 512.0 GB of RAM, 3800 GB of local NVMe SSD storage, and a 25 Gbps baseline network bandwidth. Operating on the Nitro hypervisor, the instance delivers strong multi-core CPU performance and high cached memory bandwidth, alongside strong results in Redis SET operations and static web serving. However, single-core benchmarks and single-threaded compression tasks are relatively weak, and the architecture lacks AVX or AMX instruction sets. This hardware profile supports memory-intensive databases, multi-threaded software compilation, and caching layers that leverage local NVMe storage, offering high resource density for ARM-native workloads.

    Workload Profiles

    2.3Score
    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.
