      Server Description

      A memory optimized virtual server featuring a high memory to vCPU ratio designed for lightweight and memory sensitive workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6i.large is a memory-optimized instance featuring 2 dedicated vCPUs from a single physical Intel Xeon 8375C core running at 3.5 GHz. Built on the Nitro hypervisor, it provides 16.0 GB of DDR4 memory, resulting in an 8:1 memory-to-vCPU ratio, but includes no local storage or GPU. Performance benchmarks show average single-core capabilities, such as a Geekbench single-core score of 1589.0, but poor multi-core and memory bandwidth performance, with uncached memory read speeds at 14.16 GB/sec. This hardware profile is qualitatively cost-efficient for memory-sensitive workloads with low compute demands, such as small caching layers or lightweight database instances. It is less suitable for parallelized processing, software compilation, or high-throughput database operations due to multi-core and memory bandwidth bottlenecks.

      Workload Profiles

      0.206Score
      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.
