      CPU and System Topology

      Server Description

      An arm64 virtual server featuring sixteen shared cores and local NVMe storage, optimized for multi-threaded workloads and web serving.

      Compute OptimizedGeneral PurposeBurstable & Budget

      Hetzner Cloud cax41 is an arm64 virtual server configured with 16 vCPUs powered by an Ampere Altra Neoverse-N1 processor running at 2.0 GHz. Operating under the QEMU hypervisor with a shared CPU allocation, the server includes 31.0 GB of RAM and 320 GB of local NVMe SSD storage, with no integrated GPU. Benchmarks indicate average multi-core capabilities, with a Geekbench multi-core score of 8500.0 and a stress-ng multi-core score of 29117.84, though single-core and memory performance are relatively weak. The hardware profile is optimized for parallelized workloads such as static web serving, which achieves 16.72 GB/sec throughput, multi-threaded software compilation, and database operations. It offers a cost-efficient resource density for Arm-native development and multi-threaded applications that do not require dedicated CPU cores.

      Performance

      Workload Profiles

      0.98Score
      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.
