      CPU and System Topology

      Server Description

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

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r8ae.2xlarge is an x86_64 memory-optimized server instance featuring 8 dedicated physical cores powered by an AMD EPYC 9T34 processor running at 3.4 GHz. It is equipped with 64.0 GB of RAM, providing an 8.0 GB per core ratio, but lacks local storage and integrated GPUs. Network performance is defined by a 6 Gbps baseline bandwidth. Benchmarks show top-tier single-core CPU performance and strong single-core Geekbench results, while multi-core and memory bandwidth metrics remain in the average tier. The instance supports advanced instruction sets including AVX-512 and AES. Due to its high memory-to-vCPU ratio and dedicated CPU allocation, this instance is suited for memory-intensive workloads, database operations, caching layers, and text processing applications that rely on external storage.

      Workload Profiles

      0.533Score
      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.
