      Server Description

      A memory-optimized instance featuring high-speed DDR4 RAM and 75 Gbps network bandwidth for demanding database and enterprise workloads.

      Memory OptimizedStorage & Database

      Amazon Web Services r5n.16xlarge is a memory-optimized and network-optimized instance built on the AWS Nitro System. It features 64 vCPUs powered by an Intel Xeon 8259CL processor running at 3.1 GHz, paired with 512.0 GB of DDR4 memory. The instance lacks local storage and GPUs, relying on its 75 Gbps baseline network bandwidth for high-speed connectivity to network-attached storage. Benchmarks show strong performance in large-block memory bandwidth and extended CPU instructions, though single-core performance is relatively weak. This hardware profile offers a high-density memory configuration and strong network throughput, making it a cost-effective choice for memory-intensive workloads. It is highly suited for large databases, in-memory caching, and data-intensive enterprise applications.

      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.
