      Server Description

      A dedicated dual-core compute instance featuring high-frequency AMD EPYC processors and DDR5 memory for single-threaded workloads.

      Compute Optimized

      Amazon Web Services c7a.large is a compute-optimized instance featuring 2 dedicated vCPUs and 2 physical cores powered by an AMD EPYC 9R14 processor running at 3.7 GHz. Built on the x86_64 architecture and managed by the Nitro hypervisor, it includes 4.0 GB of DDR5 memory running at 5 GHz, with no local storage or GPU accelerators. The instance delivers strong single-core CPU performance, as evidenced by top-tier single-core stress-ng and Geekbench scores. However, its multi-core scaling and memory bandwidth benchmarks are relatively weak. With a baseline network bandwidth of 1 Gbps, the c7a.large is qualitatively cost-efficient for dedicated, single-threaded compute tasks, lightweight batch processing, and basic utility workloads that do not require high memory density or local storage.

      Workload Profiles

      0.26Score
      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.
