      CPU and System Topology

      Server Description

      A memory-optimized x86_64 instance featuring dedicated AMD EPYC processing, top-tier single-core performance, and a high memory-to-core ratio for memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      The Google Cloud Platform c4d-highmem-16 is an x86_64 memory-optimized server instance powered by a dedicated AMD EPYC 9B45 processor. It features 16 vCPUs across 8 physical cores, 126.0 GB of RAM, and no local storage or GPU accelerators. Benchmarks reveal top-tier single-core CPU performance, ranking in the top 10% for stress-ng and Geekbench single-core tests, alongside strong single-threaded compression and text processing capabilities. However, multi-core performance, memory bandwidth, and database operations remain in the average tier. The processor supports AVX-512 and cryptographic acceleration but lacks AMX. This instance is qualitatively cost-efficient for memory-intensive workloads that benefit from strong single-thread execution, such as memory-cached applications, text processing, and small-scale language model inference, while relying on network storage for data persistence.

      Workload Profiles

      1.6Score
      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.
