      CPU and System Topology

      Server Description

      A compute-optimized instance featuring thirty-two dedicated AMD EPYC cores and sixty-four gigabytes of memory for compute-intensive workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c8a.8xlarge is a compute-optimized instance featuring 32 dedicated AMD EPYC 9T24 physical cores on an x86_64 architecture, running at 2.7 GHz. It is equipped with 64.0 GB of RAM, providing a 1:2 vCPU-to-memory ratio, and operates on the KVM hypervisor with a baseline network bandwidth of 10 Gbps. The instance does not include local storage or GPU hardware. Benchmark data shows strong single-core performance and strong multi-core Geekbench scores, alongside strong cryptographic and image processing capabilities. However, multi-core stress-ng and memory bandwidth benchmarks remain in the average tier. Given its dedicated compute resources and lack of local storage, this instance is highly suitable for compute-intensive workloads such as text and image processing, multi-threaded decompression, and software compilation.

      Workload Profiles

      1.43Score
      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.
