      CPU and System Topology

      Server Description

      A high-memory x86_64 server featuring forty-eight dedicated vCPUs and three hundred eighty-four gigabytes of RAM for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Google Cloud Platform n4-highmem-48 is an x86_64 memory-optimized server configured with 48 dedicated vCPUs (24 physical cores) and 384 GB of RAM, yielding 8 GB of memory per core. Powered by an Intel processor, it features an L3 cache of 260 MB and supports advanced instruction sets including AVX-512 and Intel AMX. The instance lacks bundled local storage and GPUs. Benchmark results indicate strong multi-core CPU performance, high-speed large-block memory bandwidth, and excellent database operation throughput, placing it in the top 25% of tested systems. It also delivers strong performance in static web serving and medium-model LLM prompt processing. This server is optimized for memory-intensive workloads, including enterprise databases, data analytics, and memory-heavy web applications where high memory capacity and robust multi-threaded processing are required.

      Workload Profiles

      2.7Score
      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.
