      CPU and System Topology

      Server Description

      A high-density memory-optimized virtual server featuring 256 GB of RAM and 12 cores for memory-bound database and caching workloads.

      Memory OptimizedStorage & Database

      UpCloud HIMEM-12xCPU-256GB is a memory-optimized virtual server utilizing the KVM hypervisor and x86_64 architecture. It is configured with 12 vCPUs on an AMD EPYC 7542 processor running at 2.0 GHz, paired with 256.0 GB of RAM and a 500 GB local SSD. This configuration yields a high resource density of 21.33 GB of memory per core. Benchmark data shows that while single-core CPU performance is limited, multi-core capabilities, memory bandwidth, and database operations perform at average tier levels. The server is qualitatively cost-efficient for memory-heavy deployments that do not demand high single-threaded CPU performance. It is highly suitable for memory-intensive workloads such as in-memory databases, caching layers, and data processing pipelines.

      Workload Profiles

      0.7Score
      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.
