    CPU and System Topology

    Server Description

    An ARM64-powered instance combining 384 GB of RAM and 4020 GB of local NVMe SSD storage for memory-intensive database workloads.

    Memory OptimizedStorage & Database

    Google Cloud Platform c4a-highmem-48-lssd is an ARM64-based server instance designed for memory-intensive and storage-heavy workloads. Powered by a 3.0 GHz ARM Neoverse-V2 processor, it features 48 dedicated physical cores with a single thread per core, 384.0 GB of RAM, and 4020 GB of local NVMe SSD storage. The instance demonstrates strong multi-core capabilities, with a stress-ng multi-core score of 86659.83 and high memory bandwidth, including 334.84 GB/sec for large block uncached reads. Tradeoffs include the absence of x86 vector instructions like AVX-512 and AMX, as well as the lack of GPU acceleration. This server is optimized for workloads requiring high memory-to-core ratios and fast local storage, such as in-memory databases, data analytics, and large-scale file processing.

    Workload Profiles

    3.41Score
    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.Partial coverage: missing component benchmark(s): Redis RPS (pipeline=1, SET), Redis RPS (pipeline=16, SET), PassMark Memory Mark (composite), PassMark single-thread CPU.
