      CPU and System Topology

      Server Description

      A dedicated AMD EPYC instance offering balanced compute and memory resources for reliable general-purpose enterprise workloads.

      General Purpose

      Alibaba Cloud ecs.g8a.4xlarge is a general-purpose virtual machine instance featuring 16 dedicated physical cores powered by an AMD EPYC 9T24 processor running at 2.7 GHz. Built on the KVM hypervisor, it provides 64.0 GB of system memory, yielding a balanced 4.0 GB of RAM per core, with no local storage or GPU accelerators included. Network performance is supported by a baseline bandwidth of 7 Gbps. Benchmark results show strong single-core CPU performance, though uncached large-block memory read bandwidth is a relative bottleneck, performing in the bottom 25%. With average multi-core CPU and database performance, this instance is suited for general-purpose workloads, including web serving, database operations, and multi-threaded decompression tasks.

      Workload Profiles

      0.829Score
      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.
