      CPU and System Topology

      Server Description

      A high-density memory-optimized instance featuring 192 vCPUs and top-tier multi-core performance for demanding database and caching workloads.

      Memory OptimizedGeneral Purpose

      Google Cloud Platform c4n-highmem-192 is a memory-optimized server instance featuring 192 vCPUs and 1488.0 GB of RAM, powered by dedicated Intel Xeon 8581C processors on the x86_64 architecture. With 96 physical cores and hyper-threading, it delivers top-tier multi-core performance, as evidenced by a stress-ng multi-core score of 165304.41 and a PassMark CPU score of 131185.99. The instance includes advanced instruction sets like AVX-512 and AMX, alongside a 260 MB L3 cache. While single-core performance is average, its memory bandwidth is exceptional, reaching 12801.04 GB/sec for cached small blocks. Lacking local storage and GPUs, this instance offers high resource density for memory-bound workloads. It is highly suited for large-scale database operations, Redis deployments, and parallel data processing.

      Workload Profiles

      7.59Score
      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.
