    Server Description

    A bare-metal, memory-optimized ARM server featuring dedicated physical cores, high-capacity local NVMe storage, and strong multi-core performance.

    Memory OptimizedStorage & DatabaseGeneral Purpose

    Amazon Web Services r6gd.metal is a bare-metal, memory-optimized server powered by 64 dedicated physical cores of the 64-bit ARMv8 AWS Graviton Neoverse-N1 processor running at 2.5 GHz. It is equipped with 512.0 GB of DDR4 memory, 3800 GB of local NVMe SSD instance storage, and a baseline network bandwidth of 25 Gbps. The server lacks GPU acceleration. Benchmarks indicate strong multi-core capabilities, highlighted by a stress-ng multi-core score of 97227.26 and strong cached memory bandwidth of 3792.89 GB/sec. It also excels in static web serving and Redis SET operations, achieving 74.12 million operations per second. However, single-core performance and LLM inference speeds are relatively weak. This bare-metal instance is highly suited for memory-intensive databases, caching layers, software compilation, and high-throughput web serving workloads that benefit from direct hardware access and local NVMe storage.

    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.
