      CPU and System Topology

      Server Description

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

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r8ae.8xlarge is an x86_64 memory-optimized instance featuring 32 dedicated vCPUs and 256.0 GB of RAM, powered by an AMD EPYC 9T34 processor running at 3.4 GHz. Operating on a KVM hypervisor, it provides a baseline network bandwidth of 20 Gbps but contains no local storage or GPU hardware. Benchmark results highlight strong single-core CPU performance, high memory scores, and excellent cryptographic execution, supported by hardware-accelerated instruction sets like AES and SHA_NI. Conversely, multi-core computational tasks and memory bandwidth under large block sizes fall into average performance tiers. Due to its high memory-to-vCPU ratio of 8 GB per vCPU and the absence of local storage, this instance is qualitatively cost-efficient for memory-heavy workloads that rely on network storage. It is well-suited for hosting in-memory databases, caching systems, and enterprise applications requiring substantial memory capacity.

      Workload Profiles

      1.5Score
      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.
