      CPU and System Topology

      Server Description

      An efficient shared-core virtual server combining eight AMD EPYC vCPUs with fast local NVMe storage for balanced web and text processing workloads.

      Compute OptimizedBurstable & Budget

      Hetzner Cloud cpx42 is an x86_64 virtual server configured with 8 shared AMD EPYC vCPUs, 16.0 GB of system memory, and 320 GB of local NVMe SSD storage. Operating at 2.0 GHz, the processor supports advanced vector and cryptographic instruction sets, including AVX-512 and SHA_NI. Benchmark data highlights strong single-core performance, with Geekbench single-core and single-threaded bzip3 decompression scores placing in the top 25%. Multi-core performance, memory bandwidth, and database operations fall within the average range. Given its shared CPU allocation and 1:2 memory-to-vCPU ratio, the cpx42 provides a cost-effective option for workloads that require high core counts and fast local storage but do not demand sustained, dedicated CPU performance. It is suitable for web serving, text processing, and software compilation.

      Workload Profiles

      0.64Score
      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.
