    Server Description

    An ARM64 memory-optimized server combining high-capacity RAM and fast local NVMe storage for demanding database and caching workloads.

    Memory OptimizedStorage & DatabaseGeneral Purpose

    Amazon Web Services r8gd.16xlarge is an ARM64 memory-optimized server powered by 64 dedicated AWS Graviton Neoverse-V2 physical cores running at 2.8 GHz. It features 512.0 GB of RAM, 3800 GB of local NVMe SSD storage, and 30 Gbps of baseline network bandwidth. Built on the Nitro hypervisor, this instance delivers top-tier memory bandwidth, reaching 7396.42 GB/sec for cached reads, and strong multi-core performance with a Geekbench multi-core score of 25367.0. Database operations are highly efficient, as demonstrated by Redis SET performance of 134.09 million operations per second. While single-core speeds are moderate, the combination of high memory density and fast local storage makes this server highly cost-effective for memory-intensive workloads. It is best suited for high-throughput databases, in-memory caching, and multi-threaded data processing.

    Workload Profiles

    4.8Score
    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.
