    Server Description

    An ARM64 memory-optimized instance featuring dedicated Graviton cores, substantial RAM, and high-speed local NVMe storage for data-intensive workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r6gd.12xlarge is an ARM64 memory-optimized server instance utilizing the AWS Nitro hypervisor and 48 dedicated physical cores of the AWS Graviton Neoverse-N1 processor running at 2.5 GHz. It features 384.0 GB of RAM, a 2850 GB local NVMe SSD instance store, and 20 Gbps baseline network bandwidth. Performance benchmarks reveal strong multi-core CPU capabilities, placing in the top 25% for multi-core stress-ng tests, though single-core performance and single-threaded compression tasks remain in the average to weak categories. Memory bandwidth and database operations consistently perform in the average tier. This hardware configuration is suited for memory-intensive applications, database operations, and multi-threaded processing workloads that benefit from local NVMe storage, while showing limitations in single-threaded execution and large language model text generation.

    Workload Profiles

    1.9Score
    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.
