      CPU and System Topology

      Server Description

      A high-density memory instance featuring dedicated Intel Xeon processors and advanced matrix extensions for memory-intensive computing and database workloads.

      Memory OptimizedGeneral Purpose

      Google Cloud Platform c4n-highmem-48 is an x86_64 memory-optimized server instance featuring 48 dedicated vCPUs and 372.0 GB of RAM. Powered by an Intel Xeon 8581C processor running at 2.3 GHz, it includes 24 physical cores and a 260 MB L3 cache. The instance lacks local storage and GPUs. Benchmarks show strong performance in PassMark CPU tests, encryption, and small-block memory bandwidth, alongside top-tier single-threaded bzip3 decompression. It also features Advanced Matrix Extensions (AMX) that deliver strong performance in small-scale LLM inference. Qualitatively, the high memory-to-vCPU ratio provides excellent resource density for memory-bound workloads, though external storage must be provisioned separately. It is well-suited for database operations, static web serving, and in-memory data processing.

      Workload Profiles

      2.73Score
      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.
