      CPU and System Topology

      Server Description

      A compute-optimized instance delivering top-tier single-core performance with dedicated AMD EPYC processors for compute-intensive workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c8ae.2xlarge is an x86_64 compute-optimized instance featuring 8 dedicated AMD EPYC 9T34 physical cores running at 3.4 GHz and 16.0 GB of RAM. Lacking local storage and GPU accelerators, it relies on a 6 Gbps baseline network bandwidth. Benchmarks show top-tier single-core CPU performance, while multi-core execution and memory bandwidth remain in the average tier. The 1:2 vCPU-to-RAM ratio offers a cost-effective profile for compute-heavy tasks that do not demand extensive memory. This instance is suitable for web serving, batch processing, and applications utilizing vector instructions like AVX-512.

      Workload Profiles

      0.527Score
      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.
