      Server Description

      A compute-optimized virtual server featuring forty-eight dedicated vCPUs and ninety-six gigabytes of memory for intensive processing workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c5.12xlarge is a compute-optimized instance powered by the Nitro hypervisor and an Intel Xeon 8275CL x86_64 processor. It features 48 dedicated vCPUs operating at 3.6 GHz, paired with 96.0 GB of DDR4 memory. The instance does not include local storage or GPU accelerators, relying on network-attached storage and offering a baseline network bandwidth of 12 Gbps. Performance benchmarks indicate average capabilities, with a stress-ng multi-core score of 47304.54 and a Geekbench multi-core score of 12291.0. It supports AVX-512 instructions, enhancing vector processing and cryptography tasks. Given its 1:2 RAM-to-vCPU ratio, the c5.12xlarge is highly cost-efficient for compute-heavy workloads that require high clock speeds but moderate memory footprints. It is well-suited for software compilation, batch processing, and static web serving.

      Workload Profiles

      1.7Score
      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.
