      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring dedicated AMD EPYC processors and high memory-to-core density for memory-bound enterprise workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r8ae.8xlarge is an x86_64 memory-optimized instance featuring 32 dedicated physical cores powered by an AMD EPYC 9T34 processor running at 3.4 GHz. It is configured with 256.0 GB of RAM, translating to 8.0 GB per core, and provides a baseline network bandwidth of 20 Gbps. The instance does not include local storage or GPU hardware. In benchmark evaluations, the server demonstrates strong single-core and multi-core capabilities, with Geekbench scores and Passmark encryption performance placing in the top 25%. Conversely, multi-core stress-ng tests and large-block memory bandwidth fall within the average tier. Lacking local storage, the instance is best suited for memory-intensive workloads such as database operations, in-memory caching, and text or image processing that rely on network-attached storage.

      Workload Profiles

      1.48Score
      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.
