    CPU and System Topology

    Server Description

    An ARM-based server combining forty-eight dedicated cores, high memory density, and local NVMe storage for memory-intensive database workloads.

    Memory OptimizedStorage & DatabaseCompute Optimized

    Google Cloud Platform c4a-highmem-48-lssd is an ARM-based server instance configured with 48 dedicated physical cores on the ARMv8 Neoverse-V2 architecture running at 3.0 GHz. It features 384.0 GB of RAM, providing 8.0 GB of memory per core, and includes 4020 GB of local NVMe SSD storage. Lacking hyperthreading, the instance allocates a single thread per core. In benchmarks, the server demonstrates strong multi-core performance, with stress-ng multi-core scores and large-block memory bandwidth both placing in the top 25%. Multi-threaded bzip3 decompression reaches the top 10% tier at 532.16 GB/sec. While the ARM architecture lacks x86-specific vector extensions like AVX, its high memory density and local NVMe storage offer qualitative cost efficiency for memory-intensive and storage-heavy workloads. This instance is suited for large-scale databases, in-memory caching, and multi-threaded data processing tasks.

    Workload Profiles

    3.42Score
    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.
