      CPU and System Topology

      Server Description

      A memory-dense virtual server featuring high RAM-to-core ratios and local SSD storage for memory-intensive database and caching workloads.

      Memory OptimizedStorage & Database

      UpCloud HIMEM-16xCPU-384GB is a memory-optimized KVM-based server featuring 16 shared vCPUs on an AMD EPYC 7542 processor running at 2.0 GHz. It is configured with 384.0 GB of RAM, providing 24.0 GB per core, and includes a 600 GB local SSD. Benchmark data shows a performance tradeoff: single-core CPU performance is poor, falling in the bottom 10%, whereas multi-core CPU performance, memory bandwidth, and database operations reside in the average tier. The server is qualitatively cost-efficient for memory-dense workloads that do not require dedicated or high-frequency single-core execution. It is best suited for in-memory databases, caching layers, and memory-intensive data processing workloads.

      Workload Profiles

      0.9Score
      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.
