      CPU and System Topology

      Server Description

      A compute-optimized virtual server featuring dedicated AMD EPYC processors, delivering top-tier single-core performance for compute-intensive workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c8ae.4xlarge is an x86_64 compute-optimized server instance featuring 16 dedicated vCPUs and 32.0 GB of RAM, powered by an AMD EPYC 9T34 processor running at 3.4 GHz. It operates on the KVM hypervisor and provides a baseline network bandwidth of 12 Gbps, with no local storage or GPU accelerators included. Performance benchmarks show top-tier single-core CPU capabilities, ranking in the top 10% on stress-ng, and strong Geekbench single-core and text processing results in the top 25%. Multi-core compute, memory bandwidth, and database operations perform in the average tier. This hardware profile is qualitatively cost-effective for compute-bound tasks that benefit from high single-thread performance without requiring high memory-to-vCPU ratios. It is suited for workloads such as web serving, software compilation, and text processing.

      Workload Profiles

      0.84Score
      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.
