      CPU and System Topology

      Server Description

      An x86_64 compute instance with eight dedicated AMD EPYC cores and a balanced memory-to-CPU ratio for standard workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c6a.2xlarge is an x86_64 compute-optimized server instance featuring 8 dedicated AMD EPYC 7H12 CPU cores running at 2.6 GHz and 16.0 GB of RAM. It does not include local storage or GPU accelerators, and operates with a baseline network bandwidth of 2 Gbps. Benchmark data shows average performance in Geekbench and Passmark tests, though it exhibits weaker results in stress-ng CPU tests and large-block memory bandwidth. This instance is suited for workloads requiring dedicated CPU resources without high memory demands, such as static web serving, software compilation, and standard database operations.

      Workload Profiles

      0.393Score
      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.
