      CPU and System Topology

      Server Description

      A dedicated compute-optimized instance delivering strong single-core performance and advanced vector instructions for CPU-intensive workloads.

      Compute Optimized

      Alibaba Cloud ecs.c8a.2xlarge is a compute-optimized instance featuring 8 dedicated x86_64 physical cores powered by an AMD EPYC 9T24 processor running at 2.7 GHz. It is configured with 16.0 GB of RAM, providing a 2.0 GB per core ratio, and lacks local storage or GPU accelerators. Network performance is anchored by a baseline bandwidth of 4 Gbps. Benchmarks indicate strong single-core CPU performance, placing in the top 25%, alongside average multi-core and memory performance. The processor supports advanced vector and cryptographic instructions, including AVX-512 and AES. This instance is qualitatively cost-efficient for compute-heavy workloads that do not require large memory footprints, making it suitable for web serving, cryptographic tasks, and moderate batch processing.

      Workload Profiles

      0.555Score
      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.Partial coverage: missing component benchmark(s): Memory bandwidth (read, 16 MB ~ L3).
