      CPU and System Topology

      Server Description

      A budget-friendly shared virtual server combining strong single-core AMD EPYC performance with local NVMe SSD storage for light workloads.

      Burstable & BudgetCompute Optimized

      Hetzner Cloud cpx31 is an x86_64 virtual server configured with 4 shared AMD EPYC vCPUs running at 2.0 GHz, 8.0 GB of RAM, and 160 GB of local NVMe SSD storage. Operating under the QEMU hypervisor, this instance delivers strong single-core CPU performance, as demonstrated by its stress-ng single-core score of 2681.88. However, the shared CPU allocation model introduces performance tradeoffs, resulting in weak multi-core benchmark results, such as a Geekbench multi-core score of 4053.0 and lower memory performance. The server is qualitatively cost-efficient for budget-conscious deployments, making it suitable for development environments, light database tasks, and basic web serving. It is less optimal for sustained multi-threaded workloads, software compilation, or intensive data processing.

      Workload Profiles

      0.277Score
      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.
