      CPU and System Topology

      Server Description

      A dedicated Intel Xeon virtual machine offering high memory density and advanced matrix extensions for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Google Cloud Platform c4-highmem-48 is a memory-optimized virtual machine configured with 48 vCPUs and 372 GB of RAM, delivering 7.75 GB of memory per core. Powered by a dedicated 2.3 GHz Intel Xeon 8581C processor with 24 physical cores and a 260 MB L3 cache, this x86_64 instance features advanced hardware acceleration including Intel AVX-512 and AMX. Benchmark results place this server in the top 10% for single-core processing, image manipulation, and text processing. It also shows strong multi-core performance in Passmark and Geekbench tests, alongside a high static web serving throughput of 73.99 GB/sec. Lacking local storage and GPUs, it represents a resource-dense, qualitatively cost-efficient option for memory-heavy workloads. The c4-highmem-48 is highly suited for enterprise databases, in-memory caching, software compilation, and medium-scale machine learning inference.

      Workload Profiles

      2.94Score
      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.
