      CPU and System Topology

      Server Description

      An arm64 server featuring sixty-four dedicated physical cores and half a terabyte of RAM for memory-intensive enterprise workloads.

      Memory OptimizedCompute Optimized

      The Google Cloud Platform c4a-highmem-64 is an arm64 server instance powered by 64 dedicated physical cores of the ARMv8 Neoverse-V2 architecture running at 3.0 GHz. It features 512.0 GB of RAM, establishing a memory-to-core ratio of 8.0 GB per core, with no local storage or GPU accelerators. Performance benchmarks indicate top-tier capabilities in memory bandwidth, database operations, and multi-threaded decompression, with Redis SET operations reaching 134.03 million operations per second. The instance delivers strong multi-core performance, supported by a stress-ng multi-core score of 115712.52 and an 80 MB L3 cache. Qualitatively, its ARM-based architecture provides high memory density and processing efficiency, making it an optimal fit for memory-intensive databases, high-throughput web serving, caching layers, and multi-threaded data processing workloads.

      Workload Profiles

      4.26Score
      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.
