    Server Description

    A memory-optimized x86 server featuring high-speed DDR5 RAM, local NVMe SSD storage, and advanced matrix acceleration for demanding data workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r8id.16xlarge is a memory-optimized server instance powered by an Intel Xeon 6975P-C processor with 64 vCPUs and 512.0 GB of DDR5 memory. Operating at 3.9 GHz, the dedicated CPU architecture includes 32 physical cores and a 480 MB L3 cache. The instance features 3800 GB of local NVMe SSD storage and a 30 Gbps baseline network bandwidth. Benchmark data shows top-tier performance in Geekbench multi-core tests, software compilation, and static web serving. The hardware supports advanced instruction sets including AVX-512 and Intel AMX, which drive strong performance in LLM inference and cryptographic operations. With its high memory density and fast local storage, this instance is designed for memory-intensive workloads, large databases, Redis deployments, and high-throughput data processing.

    Workload Profiles

    4.45Score
    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.
