      Server Description

      A high-density, compute-optimized server featuring dedicated AMD EPYC processors and DDR5 memory for demanding CPU-bound workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7a.8xlarge is a compute-optimized server featuring a dedicated 32-core AMD EPYC 9R14 processor running at 3.7 GHz and 64.0 GB of DDR5 memory. Built on the Nitro hypervisor, this x86_64 instance delivers strong CPU performance, ranking in the top 25% for stress-ng and Geekbench benchmarks. It excels in software compilation, database operations, and small-to-medium LLM inference, achieving top-tier prompt processing speeds. However, it lacks local storage and dedicated GPUs, relying on a 12 Gbps baseline network bandwidth for external storage connections. This configuration offers high compute density but presents a tradeoff for memory-intensive applications due to its 2.0 GB per core memory ratio.

      Workload Profiles

      2Score
      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.
