      Server Description

      A high-density compute instance featuring 128 dedicated AMD EPYC cores and DDR5 memory optimized for parallel processing and cryptographic workloads.

      Compute Optimized

      Amazon Web Services c7a.32xlarge is an x86_64 compute-optimized instance featuring 128 dedicated physical cores powered by an AMD EPYC 9R14 processor running at 3.7 GHz. It is configured with 256 GB of DDR5 memory, yielding a low memory-to-core ratio of 2.0 GB per core, and lacks local storage and GPU accelerators. Built on the Nitro hypervisor, the instance provides 50 Gbps of baseline network bandwidth. Benchmark results show top-tier multi-core CPU performance and memory bandwidth, alongside strong database and cryptographic execution. However, single-threaded performance and multi-threaded decompression fall into the average tier. This resource profile offers high compute density for parallel processing but presents a tradeoff for memory-intensive applications. It is suited for compute-heavy workloads such as software compilation, physics simulations, and CPU-based language model prompt processing.

      Workload Profiles

      6.05Score
      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.
