      CPU and System Topology

      Server Description

      An entry-level ARM64 virtual server with shared Ampere Altra processors and NVMe storage for budget-conscious, lightweight workloads.

      Burstable & BudgetGeneral Purpose

      Hetzner Cloud cax11 is an entry-level, ARM-based virtual server featuring 2 shared vCPUs from the Ampere Altra Neoverse-N1 processor family running at 2.0 GHz. It is equipped with 4.0 GB of RAM and a 40 GB NVMe SSD for local storage, operating under a QEMU hypervisor. Benchmarks reveal average single-core CPU performance, but weak multi-core and memory bandwidth capabilities, as evidenced by a Geekbench multi-core score of 1734.0 and uncached write speeds of 14.07 GB/sec. Lacking advanced vector extensions, this instance is designed for budget-conscious, low-intensity workloads. It is best utilized for lightweight web serving, software development testing, and basic background tasks.

      Workload Profiles

      0.16Score
      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.
