      Server Description

      A high-density compute server featuring ninety-six virtual cores and dedicated AMD EPYC processing for intensive multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6a.24xlarge is an x86_64 compute-optimized server featuring an AMD EPYC 7R13 processor with 96 vCPUs, 48 physical cores, and a 3.6 GHz clock speed. It is equipped with 192.0 GB of DDR4 memory, providing a 2.0 GB per core ratio, and operates on the Nitro hypervisor with a 38 Gbps baseline network bandwidth. The server lacks local storage and GPU accelerators. Benchmarks show top 10% performance in multi-core stress testing and CPU encryption, alongside top 25% performance in database operations and Redis SET transactions. Large-block memory bandwidth and web serving throughput remain in the middle 50%. This profile makes the instance highly efficient for compute-intensive workloads such as software compilation, cryptographic processing, and multi-threaded batch jobs that do not require local NVMe storage.

      Workload Profiles

      2.9Score
      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.
