      CPU and System Topology

      Server Description

      A compute-optimized virtual server featuring dedicated AMD EPYC processors and strong single-core performance for lightweight workloads.

      Compute Optimized

      Alibaba Cloud ecs.c7a.xlarge is a compute-optimized virtual server featuring 4 dedicated vCPUs on an AMD EPYC 7T83 processor running at 2.55 GHz, paired with 8.0 GB of RAM. Operating on the KVM hypervisor, this instance lacks local storage and GPU accelerators, relying on a baseline network bandwidth of 2 Gbps. Benchmark data indicates strong single-core CPU performance, though multi-core scaling and memory bandwidth are relatively weak. This hardware profile offers a cost-efficient option for compute-focused workloads that do not demand high memory density. It is best suited for lightweight web serving, single-threaded applications, text processing, and small-scale language model text generation.

      Workload Profiles

      0.248Score
      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.
