      CPU and System Topology

      Server Description

      A dedicated AMD EPYC general-purpose instance offering balanced multi-core processing and 64 GB RAM for standard multi-threaded workloads.

      General Purpose

      Alibaba Cloud ecs.g6a.4xlarge is a general-purpose instance featuring 16 dedicated physical cores powered by an AMD EPYC 7H12 processor at 2.6 GHz, paired with 64.0 GB of RAM. Operating on the KVM hypervisor, this x86_64 server lacks local storage and GPU accelerators, utilizing a baseline network bandwidth of 5 Gbps. Performance benchmarks indicate a distinct tradeoff: single-core CPU performance is poor, ranking in the bottom 10%, and uncached large-block memory bandwidth is weak. Conversely, multi-core CPU execution, cached memory reads, and cryptographic operations perform at average levels. The balanced 1:4 vCPU-to-RAM ratio makes this instance suitable for multi-threaded general-purpose workloads, such as static web serving, Redis key-value stores, and standard database operations that do not demand high single-thread throughput.

      Workload Profiles

      0.637Score
      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.
