    Server Description

    A high-capacity memory-optimized platform featuring dedicated Intel processors, massive NVMe storage, and high-speed networking for demanding database workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r6idn.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 x86_64 architecture and managed by the Nitro hypervisor, it delivers 1024.0 GB of DDR4 memory alongside 7600 GB of local NVMe SSD storage and a 200 Gbps baseline network bandwidth. Benchmark results highlight strong multi-core performance, with a Passmark CPU score of 86426.81 and a Redis SET throughput of 108.32 million operations per second. The instance is highly efficient for memory-intensive applications, offering exceptional memory bandwidth and robust cryptographic execution. It is optimized for demanding workloads such as large-scale in-memory databases, high-throughput data processing, and enterprise-grade web serving.

    Workload Profiles

    4.65Score
    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.
