    Server Description

    A memory-optimized platform combining a 512 GB RAM footprint with 2400 GB of local NVMe storage for data-intensive workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r5d.16xlarge is a memory-optimized instance featuring 64 vCPUs and 32 physical cores powered by an Intel Xeon 8259CL x86_64 processor running at 3.1 GHz. It is equipped with 512.0 GB of DDR4 RAM and 2400 GB of local NVMe SSD storage, operating on the Nitro hypervisor with a 20 Gbps baseline network speed. Benchmark results show a distinct tradeoff: single-core CPU performance and single-threaded compression tasks fall into the bottom 25%, while multi-core performance and database operations remain in the average tier. Notably, large-block memory bandwidth is strong, placing in the top 25% with read speeds of 209.41 GB/sec. This hardware profile is qualitatively cost-efficient for memory-intensive and storage-heavy workloads, making it suitable for database deployments, Redis caching, and multi-threaded data processing rather than single-threaded or compute-heavy tasks.

    Workload Profiles

    2.16Score
    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.
