      CPU and System Topology

      Server Description

      An arm64-based virtual machine featuring dedicated physical cores and high memory density for demanding database and multi-threaded workloads.

      Memory OptimizedGeneral Purpose

      Google Cloud Platform c4a-highmem-48 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 384.0 GB of RAM, yielding a high memory-to-core ratio of 8.0 GB per core, though it lacks local storage and GPU accelerators. Benchmarks indicate top-tier capabilities in multi-core processing, database operations, and memory bandwidth, with a Geekbench multi-core score of 25168.0 and a Passmark database operations score of 50138.12. The dedicated core design ensures predictable performance, making it highly cost-efficient for memory-intensive workloads. This instance is best suited for database hosting, software compilation, high-throughput web serving, and memory-bound enterprise applications.

      Workload Profiles

      3.15Score
      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.
