      Server Description

      A high frequency memory optimized virtual server delivering exceptional single core performance and DDR5 memory for specialized low concurrency enterprise workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r7iz.large is a memory-optimized instance featuring a dedicated Intel Xeon 6455B processor running at 3.9 GHz, delivering 2 vCPUs from a single physical core. It is equipped with 16.0 GB of DDR5 memory at 5 GHz, with no local storage or GPU accelerators. The instance excels in single-core performance, achieving top-tier Geekbench single-core scores and strong single-threaded compression results. However, its multi-core and memory bandwidth capabilities are limited due to the single-core hardware constraint. This profile makes the r7iz.large a qualitatively cost-efficient choice for workloads that prioritize high clock speeds and memory capacity over parallel processing, such as single-threaded applications, small database tasks, and lightweight web serving.

      Workload Profiles

      0.293Score
      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.
