      CPU and System Topology

      Server Description

      A memory-optimized x86_64 virtual server featuring dedicated AMD EPYC processors and high memory density for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r8ae.2xlarge is a memory-optimized instance featuring 8 dedicated vCPUs and 64.0 GB of RAM, powered by an x86_64 AMD EPYC 9T34 processor running at 3.4 GHz. Utilizing the KVM hypervisor, this instance provides 8.0 GB of memory per core and a baseline network bandwidth of 6 Gbps, with no local storage or GPU resources. The processor supports AVX-512 and AES cryptography extensions, delivering top-tier single-core performance alongside average multi-core and memory bandwidth capabilities. Given its high memory-to-vCPU ratio and strong single-thread execution, the ecs.r8ae.2xlarge is well-suited for memory-bound workloads, database operations, and in-memory caching platforms like Redis.

      Workload Profiles

      0.538Score
      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.
