      CPU and System Topology

      Server Description

      A high-density, memory-optimized shared instance featuring forty-eight vCPUs and three hundred eighty-four gigabytes of RAM for memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      Vultr vx1-m-48c-384gb is an x86_64 memory-optimized server within the VX1 Cloud Compute family, featuring 48 vCPUs and 24 physical AMD EPYC cores running at 2.0 GHz. It is configured with 384.0 GB of RAM, yielding 8.0 GB per core, but lacks a GPU and provides only 1 GB of network storage. Benchmarks show top-tier single-core CPU performance and large-block memory bandwidth, alongside strong multi-core and database execution speeds. However, its shared CPU allocation presents a tradeoff in processing consistency, and Passmark memory scores remain average. Qualitatively, this configuration offers high memory density at a lower cost point due to the shared CPU model. It is best suited for in-memory databases, caching layers, static web serving, and memory-heavy workloads that do not require dedicated CPU resources.

      Workload Profiles

      4.15Score
      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.
