    Server Description

    A memory-optimized configuration featuring high-capacity DDR4 RAM and integrated local NVMe SSD storage for database and caching workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r5d.12xlarge is a memory-optimized instance featuring 48 vCPUs powered by an Intel Xeon 8259CL processor running at 3.1 GHz. It is configured with 384.0 GB of DDR4 memory and 1800 GB of local NVMe SSD storage, operating on the AWS Nitro hypervisor with a 12 Gbps baseline network bandwidth. Benchmark data indicates average multi-core CPU and memory bandwidth performance, though single-core execution speeds are relatively weak. This hardware profile, combining high memory capacity with fast local storage, is well-suited for memory-intensive applications, relational databases, and caching layers that benefit from high-speed local scratch space.

    Workload Profiles

    1.65Score
    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.
