      Server Description

      A compute-optimized instance featuring dedicated AMD EPYC cores and DDR5 memory for high-performance single-threaded and batch workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7a.xlarge is a compute-optimized instance featuring 4 dedicated vCPUs and 4 physical cores powered by an AMD EPYC 9R14 processor running at 3.7 GHz. Built on the AWS Nitro hypervisor, it includes 8.0 GB of DDR5 memory at 5 GHz, but lacks local storage and GPU accelerators. The instance delivers strong single-core performance, ranking in the top 25% for stress-ng single-core CPU and Geekbench single-core benchmarks, alongside strong text processing and small-model text generation. However, it exhibits weaker performance in large-block uncached memory read bandwidth. With a baseline network bandwidth of 2 Gbps, this instance is qualitatively cost-efficient for compute-bound workloads that require dedicated CPU resources without high memory overhead. It is suited for web serving, batch processing, and single-threaded applications.

      Workload Profiles

      0.423Score
      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.
