      Server Description

      A memory-optimized server featuring one terabyte of RAM and high-bandwidth networking for demanding database and memory-cached workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6i.32xlarge is an x86_64 memory-optimized server instance running on the AWS Nitro hypervisor. It is configured with 128 vCPUs across 64 physical cores of an Intel Xeon 8375C processor operating at 3.5 GHz, paired with 1024.0 GB of DDR4 memory. The instance does not include local storage, relying instead on network-attached storage, but features a 50 Gbps baseline network bandwidth. Benchmark results show top-tier performance in Passmark CPU encryption and overall CPU scores, alongside strong multi-core processing and memory bandwidth. However, single-core performance remains average. This hardware profile is suited for memory-intensive workloads, including large-scale database operations, Redis caching, and software compilation, where high memory density and dedicated CPU allocation are required.

      Workload Profiles

      4.68Score
      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.
