      Server Description

      A high-density, 96-core compute instance featuring DDR5 memory and top-tier multi-threaded performance for intensive CPU-bound workloads.

      Compute Optimized

      Amazon Web Services c7a.24xlarge is a compute-optimized instance featuring 96 dedicated physical cores powered by an AMD EPYC 9R14 processor running at 3.7 GHz. It is equipped with 192.0 GB of high-speed 5 GHz DDR5 memory, providing 2.0 GB of RAM per core, and operates on the AWS Nitro hypervisor with 38 Gbps of baseline network bandwidth. The instance lacks local storage and GPU accelerators. Performance benchmarks place this server in the top tier for multi-core CPU execution, software compilation, and Redis operations, with strong memory bandwidth and static web serving capabilities. However, the low memory-to-core ratio and lack of local storage represent key architectural tradeoffs. The c7a.24xlarge is highly efficient for compute-dense workloads, making it suitable for software development pipelines, ray tracing, batch processing, and CPU-based machine learning inference.

      Workload Profiles

      4.38Score
      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.
