      CPU and System Topology

      Server Description

      An x86_64 memory-optimized instance featuring dedicated AMD EPYC processing, high memory density, and strong single-core performance for memory-bound workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r8ae.xlarge is a memory-optimized virtual machine featuring 4 dedicated vCPUs on a 3.4 GHz AMD EPYC 9T34 processor and 32.0 GB of RAM. Operating on the x86_64 architecture under the KVM hypervisor, this instance lacks local storage and GPU acceleration, relying on a 4 Gbps baseline network bandwidth. Benchmark data highlights top-tier single-core CPU performance, though multi-core scaling and database operations fall into average and weaker percentiles respectively. The CPU supports AVX-512 and cryptographic acceleration flags, enhancing its capability for specialized instruction sets. Given its high memory-to-vCPU ratio of 8.0 GB per core and strong single-thread execution, the ecs.r8ae.xlarge is well-suited for memory-intensive workloads, in-memory caching, and moderate data processing tasks that do not demand high parallel write throughput or local disk storage.

      Workload Profiles

      0.306Score
      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.Partial coverage: missing component benchmark(s): Memory bandwidth (read, 16 MB ~ L3).
