      Server Description

      A dedicated dual-core compute instance featuring high-speed DDR5 memory and strong single-threaded performance for lightweight processing workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7a.large is a compute-optimized instance featuring 2 dedicated vCPUs powered by an AMD EPYC 9R14 processor running at 3.7 GHz. It is equipped with 4.0 GB of DDR5 memory at 5 GHz, but lacks local storage and GPU accelerators. Built on the Nitro hypervisor, the instance demonstrates strong single-core performance, ranking in the top 25% for Geekbench single-core and single-threaded bzip3 decompression. Conversely, multi-core scaling and memory bandwidth are weaker, with PassMark memory scores falling in the bottom 10%. This resource profile makes the c7a.large a qualitatively cost-efficient option for dedicated, single-threaded compute workloads, text processing, and lightweight model inference, while being less suitable for memory-intensive databases or multi-threaded compilation tasks.

      Workload Profiles

      0.261Score
      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.
