      Server Description

      A dedicated compute-optimized instance featuring high-speed DDR5 memory and advanced Intel Xeon processors for CPU-intensive enterprise workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7i.12xlarge is a compute-optimized server instance utilizing the Nitro hypervisor and an x86_64 Intel Xeon 8488C processor. It features 48 vCPUs (24 physical cores) running at 3.2 GHz, paired with 96.0 GB of high-speed 5 GHz DDR5 memory. The instance does not include local storage or GPUs, but provides a baseline network bandwidth of 19 Gbps. Benchmark data shows strong performance in CPU-intensive tasks, including software compilation, cryptography, and ray tracing, supported by hardware-accelerated instruction sets like AVX-512 and AMX. Memory read bandwidth is also highly rated, though write speeds and multi-core stress tests sit in the average tier. This configuration is highly suited for compute-bound workloads, database operations, static web serving, and medium-scale LLM inference where high memory-to-CPU ratios are not required.

      Workload Profiles

      2.96Score
      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.
