      Server Description

      A memory-optimized x86_64 instance featuring one terabyte of RAM, high-speed network bandwidth, and dedicated Intel Xeon processing power.

      Memory OptimizedStorage & DatabaseGeneral Purpose

      Amazon Web Services r6in.32xlarge is a memory-optimized instance featuring 128 vCPUs and 64 physical cores powered by an Intel Xeon 8375C processor running at 3.5 GHz. Built on the AWS Nitro hypervisor, it delivers 1024.0 GB of DDR4 memory and a high-speed 200 Gbps baseline network bandwidth. While it lacks local storage, its architectural design is optimized for network-attached EBS performance. Benchmark results show top-tier performance in CPU encryption, extended instructions, and ray tracing, alongside strong multi-core processing and memory bandwidth. This profile makes the instance highly efficient for memory-intensive workloads without requiring local disk storage. It is best suited for in-memory databases, large-scale enterprise database operations, and high-throughput data processing tasks.

      Workload Profiles

      4.59Score
      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.
