      Server Description

      An entry-level compute-optimized x86_64 virtual server featuring dedicated AMD EPYC processing and a balanced, low-memory hardware profile.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6a.large is a compute-optimized instance featuring 2 vCPUs and 4.0 GB of DDR4 memory, running on a dedicated 3.6 GHz AMD EPYC 7R13 processor. Built on the AWS Nitro hypervisor, this x86_64 server does not include local storage or GPU accelerators, and delivers a baseline network bandwidth of 1 Gbps. Performance benchmarks show strong single-core CPU capabilities, though multi-core performance and memory bandwidth are relatively weak, placing in the bottom 25% and 10% respectively. The 1:2 vCPU-to-RAM ratio provides a cost-efficient profile for compute-focused tasks with low memory requirements. It is best suited for lightweight single-threaded applications, basic web serving, and text processing workloads.

      Workload Profiles

      0.16Score
      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.
