      CPU and System Topology

      Server Description

      An arm64 virtual server offering eight shared cores and local NVMe storage for cost-efficient web serving and general-purpose workloads.

      Burstable & BudgetGeneral Purpose

      Hetzner Cloud cax31 is an arm64 virtual server featuring 8 vCPUs and 8 physical cores powered by an Ampere Altra Neoverse-N1 processor running at 2.0 GHz. It is configured with a shared CPU allocation, 16.0 GB of RAM, and 160 GB of local NVMe SSD storage. Benchmark results place its multi-core CPU and memory bandwidth performance in the average tier, though single-core execution, encryption, and LLM inference speeds are relatively weak. The server demonstrates solid capabilities in static web serving, reaching a throughput of 8.6 GB/sec, and database operations. Lacking a GPU and complimentary public IPv4 addresses, the cax31 represents a cost-efficient, resource-dense option for general-purpose workloads, software compilation, and web serving where dedicated CPU resources are not a strict requirement.

      Workload Profiles

      0.554Score
      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.
