      CPU and System Topology

      Server Description

      A dedicated AMD EPYC compute instance featuring a one-to-one core-to-thread ratio and strong single-core performance for compute-bound workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c7a-nps1.8xlarge is an x86_64 compute-optimized server featuring 32 dedicated AMD EPYC 7T83 physical cores and vCPUs running at 2.55 GHz. It is equipped with 64.0 GB of RAM, providing 2.0 GB of memory per core, and operates on a KVM hypervisor with an 8 Gbps baseline network bandwidth. The instance does not include local storage or GPU accelerators. Performance benchmarks show strong single-core CPU capabilities, ranking in the top 25%, while multi-core execution, memory bandwidth, and database operations perform in the average tier. This hardware profile is qualitatively cost-efficient for compute-heavy tasks that benefit from dedicated, non-hyperthreaded execution resources. It is suited for workloads such as software compilation, static web serving, and single-threaded processing tasks.

      Workload Profiles

      1.18Score
      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.
