      Server Description

      A high-density bare-metal server featuring dedicated AMD EPYC processors and DDR5 memory for demanding compute-intensive and multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7a.metal-48xl is a bare-metal, compute-optimized server featuring 192 dedicated physical cores and 192 vCPUs powered by an AMD EPYC 9R14 processor running at 3.7 GHz. Built on the x86_64 architecture, it includes 384.0 GB of DDR5 memory at 5 GHz, providing 2.0 GB of RAM per core. The instance lacks local storage and dedicated GPUs but delivers a baseline network bandwidth of 50 Gbps. Benchmark data shows top-tier performance in multi-core processing, memory bandwidth, software compilation, and Redis operations. It also excels in LLM prompt processing. This server is highly efficient for compute-heavy tasks, offering a dense allocation of dedicated resources without the overhead of virtualization. It is best suited for high-performance computing, large-scale software compilation, CPU-based machine learning inference, and high-throughput web serving.

      Workload Profiles

      7.53Score
      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.
