      CPU and System Topology

      Server Description

      A dedicated AMD EPYC virtual server delivering strong single-core performance and balanced memory for predictable general-purpose workloads.

      General Purpose

      Vultr vx1-g-4c-16g is a general-purpose virtual server from the VX1 Cloud Compute family, featuring 4 dedicated vCPUs powered by an AMD EPYC processor running at 2.0 GHz. Built on the x86_64 architecture, the server is equipped with 16.0 GB of RAM and a highly constrained 1 GB NVMe SSD. Performance benchmarks reveal a distinct contrast: single-core operations, single-threaded compression, and text processing rank in the top tier, whereas multi-core scaling, software compilation, and multi-threaded decompression fall into average or weak categories. With its dedicated CPU allocation, this instance provides stable, predictable performance. It is best suited for general-purpose workloads, single-threaded applications, and lightweight web serving, though its minimal local storage capacity requires external storage solutions for data-intensive tasks.

      Workload Profiles

      0.63Score
      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.
