      Server Description

      A high-core-density compute instance delivering top-tier multi-threaded performance and high-speed memory bandwidth for parallel processing workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6a.48xlarge is a compute-optimized instance featuring 192 vCPUs and 96 physical cores powered by an AMD EPYC 7R13 processor running at 3.6 GHz. Built on the AWS Nitro hypervisor, it includes 384.0 GB of DDR4 memory at 3 GHz, offering 2.0 GB of RAM per core. The instance lacks local storage and GPUs but provides a baseline network bandwidth of 50 Gbps. Benchmarks indicate top-tier multi-core CPU and memory performance, with outstanding results in PassMark CPU, encryption, and physics tests. It also delivers strong performance in software compilation and Redis SET operations. This instance is highly efficient for parallel processing workloads, making it suitable for high-performance computing, batch processing, static web serving, and CPU-based machine learning inference.

      Workload Profiles

      5.03Score
      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.
