    CPU and System Topology

    Server Description

    An ARM64 server combining forty-eight dedicated cores, high memory density, and local NVMe storage for data-intensive workloads.

    Memory OptimizedStorage & DatabaseCompute Optimized

    Google Cloud Platform c4a-highmem-48-lssd is an ARM64 server instance featuring 48 dedicated physical cores on the ARMv8 Neoverse-V2 architecture running at 3.0 GHz. It is equipped with 384 GB of RAM, establishing an 8.0 GB per core ratio, and includes 4020 GB of local NVMe SSD storage. Benchmark results place its multi-core CPU performance and memory bandwidth in the top 25% tier, with uncached large-block read bandwidth reaching 334.84 GB/sec and multi-threaded bzip3 decompression at 532.16 GB/sec. Conversely, single-core CPU performance sits in the middle 50% tier. Lacking GPU hardware and x86-specific vector extensions, this instance offers a resource-dense, qualitatively cost-efficient profile for memory-intensive and storage-heavy workloads. It is highly suitable for large-scale databases, multi-threaded data processing, and memory-optimized enterprise applications.

    Workload Profiles

    3.4Score
    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.
