      CPU and System Topology

      Server Description

      An arm64 compute-optimized instance featuring thirty-two dedicated physical cores for efficient multi-threaded processing and parallel workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c6r.8xlarge is an arm64 compute-optimized server instance featuring 32 dedicated physical cores powered by an Ampere Altra processor running at 2.8 GHz. It is equipped with 64.0 GB of memory, yielding a 2.0 GB per core ratio, and operates under a KVM hypervisor with 8 Gbps baseline network bandwidth. The instance does not include local storage or GPU hardware. Benchmark data shows average multi-core CPU and memory performance, with a strong multi-threaded bzip3 decompression speed of 217.66 GB/sec, though single-core performance remains relatively weak. This profile offers a cost-efficient option for highly parallelized workloads. It is best suited for multi-threaded applications, software compilation, static web serving, and moderate database operations.

      Workload Profiles

      1.65Score
      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.
