      CPU and System Topology

      Server Description

      An ARM-powered instance featuring high memory density, top-tier memory bandwidth, and strong single-threaded compression performance for memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      Google Cloud Platform c4a-highmem-8 is an ARM-based instance featuring 8 dedicated vCPUs powered by a 3.0 GHz ARMv8 Neoverse-V2 processor and 64 GB of RAM. This configuration provides a high memory-to-core ratio of 8.0 GB per vCPU. The instance does not include local storage or integrated GPUs. In benchmark testing, the c4a-highmem-8 demonstrates top-tier memory performance, with its Passmark memory score in the top 10% and large-block read-only memory bandwidth in the top 25%. Single-threaded compression and text processing also show strong results. Conversely, cryptographic performance is a notable tradeoff, scoring in the bottom 25% on the Passmark encryption test. With its high memory capacity and strong memory bandwidth, this instance is suited for memory-intensive applications, text processing, and database operations that do not require local disk storage.

      Workload Profiles

      0.93Score
      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.
