      CPU and System Topology

      Server Description

      A compute-optimized server featuring dedicated AMD EPYC cores and balanced memory performance for compute-intensive workloads.

      Compute Optimized

      Alibaba Cloud ecs.c7a-nps1.8xlarge is a compute-optimized instance from the ecs.c7a family, featuring 32 dedicated AMD EPYC 7T83 physical cores running at 2.55 GHz on the x86_64 architecture. With 32 vCPUs and 64.0 GB of RAM, it maintains a 1:2 vCPU-to-RAM ratio. The instance does not include local storage or GPU accelerators, relying on an 8 Gbps baseline network bandwidth. Performance benchmarks show strong single-core CPU capabilities and strong memory performance, while multi-core processing and memory bandwidth remain in the average tier. This hardware profile is qualitatively cost-efficient for dedicated compute workloads that do not require high memory density. It is suited for applications such as web serving, multi-threaded decompression, and database operations.

      Workload Profiles

      1.19Score
      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.
