      CPU and System Topology

      Server Description

      A resource-dense virtual server featuring sixteen shared cores and local NVMe storage for balanced multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      Hetzner Cloud cx53 is an x86_64 virtual server built on the QEMU hypervisor, featuring 16 shared AMD EPYC vCPUs running at 2.0 GHz and 31.0 GB of system memory. It includes a bundled 320 GB NVMe SSD for local storage but lacks dedicated GPU hardware and complimentary public IPv4 addresses. Benchmark data shows strong single-core performance in stress-ng and small-model LLM text generation, though Geekbench single-core and text processing metrics are poor. Most other workloads, such as multi-core processing, memory bandwidth, and database operations, perform in the average range. With a 1:2 RAM-to-vCPU ratio and shared CPU allocation, the cx53 represents a cost-efficient option for multi-threaded tasks that do not require dedicated CPU resources. It is well-suited for static web serving, software compilation, and moderate database workloads.

      Workload Profiles

      1.5Score
      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.
