      CPU and System Topology

      Server Description

      A high-density memory-optimized server featuring massive RAM capacity for memory-bound enterprise applications and large in-memory databases.

      Memory OptimizedStorage & Database

      Google Cloud Platform m1-ultramem-40 is an x86_64 memory-optimized server configured with 40 dedicated vCPUs and 961.0 GB of RAM, yielding 24.02 GB of memory per core. Powered by an Intel Xeon processor running at 2.2 GHz across 20 physical cores, this instance does not include local storage or GPUs. Benchmark data reveals a significant performance tradeoff: single-core CPU execution is weak, ranking in the bottom 10%, whereas multi-core CPU performance and memory bandwidth fall into the average tier. Qualitatively, this server offers high memory density for memory-bound workloads, though compute-heavy tasks may find the 2.2 GHz clock speed limiting. It is highly suited for large in-memory databases, Redis deployments, and memory-intensive enterprise applications that do not require local NVMe storage.

      Workload Profiles

      0.66Score
      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.
