      CPU and System Topology

      Server Description

      An ARM64 compute-optimized instance with dedicated Ampere Altra cores, delivering balanced multi-threaded performance for scale-out workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c6r.2xlarge is an ARM64 compute-optimized instance featuring 8 dedicated Ampere Altra vCPUs running at 2.8 GHz and 16.0 GB of RAM. Operating on the KVM hypervisor, it provides a baseline network bandwidth of 2 Gbps with no local storage or GPU hardware. Performance benchmarks reveal a clear tradeoff: multi-core capabilities and memory bandwidth are average, as demonstrated by a stress-ng multi-core score of 14295.27 and 11.05 million operations per second in Redis SET tests. Conversely, single-core performance is weak, with Geekbench single-core and PassMark CPU scores falling into the bottom 25% tier. This instance is best suited for multi-threaded ARM64 workloads, static web serving, and software compilation, offering a cost-efficient, dedicated resource profile for scale-out applications that do not require high single-threaded or cryptographic performance.

      Workload Profiles

      0.59Score
      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.
