      Server Description

      A memory-optimized x86_64 virtual server featuring a high RAM-to-vCPU ratio and dedicated Intel Xeon processing for memory-intensive workloads.

      Memory Optimized

      Amazon Web Services r6i.2xlarge is a memory-optimized instance featuring an x86_64 Intel Xeon 8375C processor with 8 vCPUs (4 physical cores) running at 3.5 GHz. It is configured with 64.0 GB of DDR4 memory, providing a high 1:8 vCPU-to-RAM ratio, but includes no local storage or GPU accelerators. Operating on the Nitro hypervisor, it delivers a baseline network bandwidth of 3 Gbps. Benchmark results place the instance in the average tier for most operations, including a Geekbench multi-core score of 6046.0 and Redis SET throughput of 7.96 million operations per second, though memory-intensive Passmark scores fall into the lower quartile. This instance is qualitatively cost-efficient for memory-heavy workloads that do not require massive parallel compute, making it well-suited for database operations, in-memory caching, and static web serving.

      Workload Profiles

      0.59Score
      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.
