    Server Description

    A memory-optimized instance combining dedicated AMD EPYC processing, 64 GB of RAM, and fast local NVMe SSD storage for memory-bound workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r5ad.2xlarge is a memory-optimized instance featuring an AMD EPYC 7571 processor with 8 vCPUs, 4 physical cores, and a 2.2 GHz clock speed. Built on the x86_64 architecture and managed by the Nitro hypervisor, it delivers 64.0 GB of DDR4 memory alongside a bundled 300 GB local NVMe SSD instance store. While CPU and memory bandwidth benchmarks generally fall into the lower percentiles, with stress-ng and Geekbench scores in the bottom 10% to 25%, the instance maintains average performance in Passmark CPU encryption and memory tests. With a 2 Gbps baseline network bandwidth, the r5ad.2xlarge is designed for memory-intensive workloads that benefit from local scratch space, such as caching layers, distributed in-memory databases, and moderate data processing tasks where memory capacity is prioritized over raw compute speed.

    Workload Profiles

    0.293Score
    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.
