      Server Description

      A high-density bare-metal server featuring 192 AMD EPYC vCPUs and 384 GB RAM for demanding compute-intensive workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6a.metal is a bare-metal, compute-optimized server featuring 192 vCPUs across 96 physical AMD EPYC 7R13 cores running at 3.6 GHz. Built on the x86_64 architecture, it includes 384.0 GB of DDR4 memory and a baseline network bandwidth of 50 Gbps, with no local storage or GPUs. Benchmark data highlights top-tier performance in multi-core processing, software compilation, and Redis operations, alongside strong large-block memory bandwidth. The lack of local storage and GPU acceleration represents a clear tradeoff, positioning this server as a highly efficient option for compute-intensive tasks rather than storage-heavy or graphics-focused workloads. It is best suited for high-performance computing, large-scale software compilation, static web serving, and CPU-based machine learning inference.

      Workload Profiles

      5.16Score
      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.
