      CPU and System Topology

      Server Description

      A cost-efficient shared-CPU virtual server featuring AMD EPYC processors and fast NVMe storage for balanced general-purpose workloads.

      Burstable & BudgetGeneral Purpose

      Hetzner Cloud cx43 is an x86_64 virtual server powered by an AMD EPYC processor with 8 shared vCPUs and 16.0 GB of RAM. Running on the QEMU hypervisor, it features a 160 GB NVMe SSD and lacks dedicated GPU hardware. The instance delivers average multi-core performance, with a stress-ng multi-core score of 20252.78 and a Geekbench multi-core score of 5615.0. While single-threaded performance is relatively weak, the server maintains solid throughput for database operations, achieving 14.46 million Redis SET operations per second, and static web serving at 10.98 GB/sec. Due to its shared CPU architecture, the cx43 is a cost-effective option for general-purpose workloads, software compilation, and web serving, though it is less suited for sustained, compute-intensive tasks.

      Performance

      Workload Profiles

      0.86Score
      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.
