      Server Description

      A memory-optimized virtual server featuring high DDR4 RAM density and balanced multi-core performance for memory-bound enterprise workloads.

      Memory OptimizedStorage & Database

      Amazon Web Services r5n.4xlarge is a memory-optimized instance powered by an Intel Xeon 8259CL processor with 16 vCPUs and 128.0 GB of DDR4 memory. Built on the Nitro hypervisor, it features a 3.1 GHz clock speed, 35 MB L3 cache, and a baseline network bandwidth of 16 Gbps. The instance does not include local storage or GPUs. Benchmark data shows average multi-core CPU and memory bandwidth performance, alongside weaker single-core processing capabilities. This hardware profile delivers qualitative cost efficiency for memory-intensive applications by providing a high 8:1 RAM-to-vCPU ratio. It is best suited for workloads such as in-memory databases, caching layers, and memory-bound data processing.

      Workload Profiles

      0.753Score
      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.
