      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring dedicated AMD EPYC processors and a high memory-to-vCPU ratio for memory-bound workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r6a.large is a memory-optimized instance featuring 2 dedicated vCPUs powered by an AMD EPYC 7H12 processor at 2.6 GHz and 16.0 GB of RAM. Operating on the x86_64 architecture under KVM virtualization, this instance offers a high memory-to-vCPU ratio of 8.0 GB per core, though it lacks local storage and GPU capabilities. Performance benchmarks show modest results, with an average Geekbench single-core score of 1264.0, while multi-core CPU and memory bandwidth metrics fall into the lower percentiles. With a baseline network bandwidth of 1 Gbps, this instance represents a qualitative balance of high memory density and low compute overhead. It is best suited for lightweight memory-bound workloads, small caching layers, or database instances that do not require intensive CPU processing.

      Workload Profiles

      0.137Score
      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.
