      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring dedicated AMD EPYC cores and a high memory-to-CPU ratio for single-threaded, memory-bound workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r8ae.large is a memory-optimized KVM-based instance featuring 2 dedicated physical cores of an AMD EPYC 9T34 processor clocked at 3.4 GHz. Equipped with 16.0 GB of RAM, it provides a high memory-to-core ratio of 8.0 GB per core, though it lacks local storage and GPU capabilities. Performance benchmarks show strong single-core CPU execution, ranking in the top 25% for stress-ng, but multi-core performance and database operations are weak due to the 2-core limitation. The instance provides a baseline network bandwidth of 3 Gbps. Qualitatively, it offers a cost-effective entry point for memory-intensive workloads that do not demand high parallel compute scaling. It is best suited for lightweight caching, single-threaded processing, and basic web serving.

      Workload Profiles

      0.199Score
      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.
