      CPU and System Topology

      Server Description

      A cost-efficient shared-CPU virtual server featuring sixteen AMD EPYC cores and local NVMe SSD storage for multi-threaded workloads.

      Compute OptimizedBurstable & BudgetStorage & Database

      Hetzner Cloud cpx51 is an x86_64 virtual server featuring 16 shared AMD EPYC vCPUs operating at 2.0 GHz, paired with 31.0 GB of RAM and 360 GB of local NVMe SSD storage. The hardware profile lacks dedicated GPU resources and complimentary public IPv4 addresses. Performance benchmarks place the cpx51 in the average tier for multi-core processing, memory bandwidth, and database operations, though single-core CPU performance is positioned in the bottom 10%. This resource density offers a cost-effective option for multi-threaded applications. The server is suited for workloads such as static web serving, software compilation, and moderate database operations that benefit from multi-core execution without requiring dedicated CPU allocation.

      Workload Profiles

      1.02Score
      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.
