      CPU and System Topology

      Server Description

      A memory-dense, dedicated x86_64 compute platform featuring advanced matrix acceleration for high-throughput database and CPU-based inference workloads.

      Memory OptimizedGeneral Purpose

      The Google Cloud Platform c4n-highmem-48 is a memory-optimized server instance featuring 48 dedicated vCPUs and 372.0 GB of RAM, powered by an Intel Xeon 8581C processor on the x86_64 architecture. With 24 physical cores and hyper-threading, it delivers strong multi-threaded performance, supported by a 260 MB L3 cache and advanced instruction sets like AVX-512 and Intel AMX. Benchmarks show top-tier results in single-core tasks, image processing, and text processing, alongside strong multi-core and cryptographic execution. The instance lacks local storage and GPUs, focusing resources entirely on memory density and processing power. This configuration is highly efficient for memory-intensive workloads, software compilation, database operations, and CPU-based machine learning inference.

      Workload Profiles

      2.72Score
      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.
