      CPU and System Topology

      Server Description

      A dedicated AMD EPYC compute-optimized instance delivering strong single-core performance and balanced memory read capabilities for compute-bound workloads.

      Compute Optimized

      Alibaba Cloud ecs.c7a.8xlarge is a compute-optimized instance featuring 32 dedicated physical cores powered by an AMD EPYC 7T83 processor at 2.55 GHz. It is equipped with 64.0 GB of RAM, resulting in a 2.0 GB per core ratio, and operates on the 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 execution and memory scores, though large-block memory write bandwidth is a relative bottleneck. This hardware profile is suited for compute-intensive workloads, including web serving, multi-threaded decompression, and small-to-medium language model inference.

      Workload Profiles

      1.12Score
      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.
