      Server Description

      A memory-optimized server featuring high memory density and balanced multi-core performance for database and caching workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r4.8xlarge is a memory-optimized fourth-generation instance featuring 32 vCPUs and 244.0 GB of RAM. Powered by an Intel Xeon E5-2686 v4 processor running at 2.3 GHz, this x86_64 architecture server utilizes the Xen hypervisor. It does not include local storage or GPU accelerators. Performance benchmarks show a distinct tradeoff: single-core performance is poor, ranking in the bottom 10%, whereas multi-core performance and memory bandwidth consistently reach average tiers. This resource profile makes the r4.8xlarge qualitatively cost-effective for memory-bound workloads rather than compute-intensive tasks. It is best suited for databases, Redis caching layers, and memory-intensive enterprise applications that benefit from its high memory-to-vCPU ratio and 12 Gbps baseline network bandwidth.

      Workload Profiles

      0.953Score
      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.
