    Server Description

    A memory-optimized instance featuring high-speed DDR5 RAM, local NVMe storage, and strong single-core performance for database and caching workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r8id.xlarge is a memory-optimized instance featuring 4 dedicated vCPUs and 2 physical Intel Xeon 6975P-C cores running at 3.9 GHz. It is equipped with 32.0 GB of high-speed 7 GHz DDR5 memory and a bundled 237 GB NVMe SSD local instance store. Operating on the Nitro hypervisor, the instance supports advanced CPU instructions including AVX-512 and Intel AMX. Benchmark data reveals strong single-core performance, particularly in text processing and single-threaded compression, though multi-core scaling and uncached memory read bandwidth are relatively weak. With a baseline network speed of 2 Gbps, this instance provides a balanced qualitative cost profile for memory-intensive applications. It is best suited for in-memory databases, caching layers, text processing, and lightweight web serving workloads.

    Workload Profiles

    0.547Score
    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.
