      Server Description

      A dedicated AMD-powered compute instance with a balanced memory-to-core ratio for standard web serving and software compilation workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c5a.2xlarge is an x86_64 compute-optimized server featuring an AMD EPYC 7R32 processor with 8 vCPUs (4 physical cores) running at 3.3 GHz and 16.0 GB of DDR4 memory. Operating on the AWS Nitro hypervisor, this instance provides a baseline network bandwidth of 2 Gbps and lacks local storage. Benchmark data shows average performance in Geekbench single-core and multi-core tests, software compilation, and static web serving, though raw stress-ng CPU metrics and uncached memory bandwidth are weaker. With a 1:2 vCPU-to-RAM ratio and dedicated CPU allocation, it offers a balanced, cost-effective profile for compute-focused workloads. It is best suited for static web serving, software compilation, and moderate database operations, while being less optimal for memory-heavy tasks or large language model inference.

      Workload Profiles

      0.428Score
      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.
