      CPU and System Topology

      Server Description

      A balanced general-purpose instance offering 32 vCPUs and 128 GB memory powered by AMD EPYC hardware for multi-threaded workloads.

      General Purpose

      Alibaba Cloud ecs.g6a.8xlarge is a general-purpose server instance built on the x86_64 AMD EPYC 7H12 processor operating at 2.6 GHz. It provides 32 vCPUs across 16 physical cores, paired with 128 GB of RAM and an 8 Gbps baseline network interface. The instance includes no local storage, relying on attached cloud storage solutions. Multi-threaded benchmark testing reflects consistent mid-range execution, recording 27.69 million Redis SET operations per second and a PassMark CPU score of 31756.69. However, single-core processing power and uncached memory bandwidth show lower relative throughput. The balanced memory-to-vCPU ratio offers practical cost efficiency for core-dense, parallel workloads such as web serving, software build pipelines, and enterprise application backends.

      Workload Profiles

      1Score
      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.
