      CPU and System Topology

      Server Description

      An arm64 virtual server with shared Ampere Altra processors and local NVMe storage for multi-threaded workloads.

      Compute OptimizedBurstable & BudgetGeneral Purpose

      Hetzner Cloud cax31 is an arm64 virtual server featuring 8 shared vCPUs powered by an Ampere Altra Neoverse-N1 processor running at 2.0 GHz. It is equipped with 16.0 GB of RAM, providing 1.95 GB per core, and includes 160 GB of local NVMe SSD storage. Operating under the QEMU hypervisor, this instance delivers average multi-core performance in stress-ng and software compilation benchmarks, though its single-core metrics and memory bandwidth for uncached blocks are relatively weak. The server lacks dedicated GPU hardware and does not include complimentary public IPv4 addresses. It is qualitatively cost-efficient for resource-dense, multi-threaded workloads that tolerate shared CPU allocation. The cax31 is best suited for static web serving, lightweight database operations, and basic CI/CD or software compilation tasks.

      Workload Profiles

      0.548Score
      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.
