      CPU and System Topology

      Server Description

      A dedicated compute-optimized instance featuring high-frequency processors, strong single-core performance, and balanced networking for compute-intensive workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c8ae.8xlarge is an x86_64 compute-optimized instance featuring 32 dedicated AMD EPYC 9T34 physical cores running at 3.4 GHz, paired with 64.0 GB of RAM. This configuration provides a resource density of 2.0 GB of memory per core. The instance lacks local storage and GPU accelerators, but delivers a baseline network bandwidth of 20 Gbps. Performance benchmarks show strong single-core capabilities, with Geekbench single-core and stress-ng single-core scores in the top 25%, alongside strong cryptographic and memory performance. Multi-core performance and database operations fall within the average range. Due to the 1:2 memory-to-CPU ratio and lack of local storage, this instance is optimized for compute-heavy workloads rather than memory-intensive applications. It is well-suited for web serving, software compilation, text processing, and cryptographic tasks.

      Workload Profiles

      1.47Score
      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.
