      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring dedicated AMD EPYC processors and high memory density for demanding in-memory and text-processing workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r8ae.4xlarge is a memory-optimized instance featuring 16 dedicated physical cores on an AMD EPYC 9T34 processor running at 3.4 GHz. Equipped with 128.0 GB of RAM, it delivers a high memory-to-vCPU ratio of 8.0 GB per core. The instance lacks local storage and GPU accelerators, utilizing a 12 Gbps baseline network bandwidth. Benchmarks highlight top-tier single-core capabilities, with stress-ng single-core and Geekbench text processing scores in the top 10%, alongside strong memory performance in the top 25%. Multi-core and memory bandwidth metrics remain in the average tier. This hardware profile makes the ecs.r8ae.4xlarge a qualitatively cost-efficient option for memory-intensive workloads, such as in-memory databases, caching layers, and text processing pipelines, where high RAM capacity is required but local storage is not a necessity.

      Workload Profiles

      0.858Score
      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.
