      Server Description

      An optimized memory instance featuring high speed DDR5 RAM and strong single core processing capabilities for memory intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r8i.xlarge is a memory-optimized instance featuring 4 vCPUs, 2 physical Intel Xeon 6975P-C cores, and 32.0 GB of DDR5 RAM running at 7 GHz. Built on the Nitro hypervisor, it features a 480 MB L3 cache and a baseline network speed of 2 Gbps, with no local storage. Benchmarks show strong single-core performance, including a Geekbench single-core score of 1890.0 and top-tier text processing, though multi-core and memory bandwidth metrics are weak. Qualitatively, this instance offers high memory density relative to its compute resources, making it a cost-efficient choice for memory-intensive workloads that do not require heavy parallel processing. It is well-suited for workloads such as in-memory databases, caching layers like Redis, and text processing applications.

      Workload Profiles

      0.527Score
      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.
