      Server Description

      A compute-optimized x86_64 instance featuring dedicated AMD EPYC processors and high-speed DDR5 memory for single-threaded and compute-bound workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7a.2xlarge is a compute-optimized instance featuring 8 dedicated physical cores and 8 vCPUs powered by an AMD EPYC 9R14 processor running at 3.7 GHz. It is equipped with 16.0 GB of high-speed DDR5 memory at 5 GHz, but lacks local storage and GPU accelerators. Operating on the Nitro hypervisor, it delivers a baseline network bandwidth of 3 Gbps. Benchmark results highlight strong single-core performance, particularly in Geekbench single-core tests and single-threaded bzip3 decompression, though uncached large-block memory bandwidth is a relative bottleneck. This resource profile makes the instance highly suitable for compute-heavy, single-threaded tasks, software compilation, and static web serving, while offering a balanced cost-to-performance ratio for workloads that do not require extensive memory capacity.

      Workload Profiles

      0.67Score
      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.
