      Server Description

      A high-density, memory-optimized x86 platform featuring 1024 GB of RAM and 128 vCPUs for demanding database and enterprise workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6i.32xlarge is a memory-optimized instance featuring 128 vCPUs, 1024.0 GB of DDR4 memory, and an Intel Xeon 8375C processor running at 3.5 GHz. Operating on the AWS Nitro hypervisor, it delivers a baseline network bandwidth of 50 Gbps without local storage or GPU accelerators. Benchmarks show top-tier performance in Passmark CPU and encryption tests, alongside strong multi-core and memory bandwidth capabilities. Conversely, single-core performance and large-scale LLM text generation remain average to weak. This high-density memory profile is highly efficient for memory-bound enterprise workloads, making it an appropriate fit for in-memory databases like Redis, high-throughput web serving, and complex database operations.

      Workload Profiles

      4.6Score
      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.
