      CPU and System Topology

      Server Description

      A memory-optimized, x86_64 server featuring 48 dedicated vCPUs and 372 GB RAM, optimized for database operations and CPU-based inference.

      Memory OptimizedGeneral Purpose

      Google Cloud Platform c4-highmem-48 is a memory-optimized server instance featuring 48 dedicated vCPUs and 372 GB of RAM, powered by an Intel Xeon 8581C processor at 2.3 GHz. Built on the x86_64 architecture, it provides 24 physical cores and a 260 MB L3 cache. The instance lacks local storage and GPU accelerators but includes Intel Advanced Matrix Extensions (AMX) and AVX-512. Benchmarks reveal top-tier performance in image and text processing, alongside strong results in software compilation, database operations, and small-model LLM inference. However, text generation for large 70B models is weak due to the absence of a GPU. This instance is highly efficient for memory-intensive workloads, database hosting, and CPU-based machine learning inference.

      Workload Profiles

      2.92Score
      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.
