      Server Description

      A dedicated dual-vCPU AMD EPYC compute instance delivering strong single-core performance for lightweight, memory-constrained workloads.

      Compute Optimized

      The Amazon Web Services c6a.large is a compute-optimized instance utilizing the Nitro hypervisor and an x86_64 AMD EPYC 7R13 processor running at 3.6 GHz. It features 2 dedicated vCPUs and 4.0 GB of DDR4 memory, with no local storage or GPU. Benchmarks indicate strong single-core CPU performance, scoring in the top 25% on stress-ng, but weak multi-core and memory bandwidth results, with cached read bandwidth and database operations falling into the bottom 10%. This instance provides a low-cost entry point for dedicated AMD compute resources, making it suitable for lightweight, single-threaded tasks, basic web serving, and text processing. However, its limited memory capacity and poor multi-core scaling make it less suitable for database hosting or software compilation.

      Workload Profiles

      0.168Score
      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.
