      Server Description

      A dedicated 36-vCPU compute-optimized instance designed for high-throughput CPU workloads, software compilation, and multi-threaded data processing.

      Compute Optimized

      Amazon Web Services c4.8xlarge is a compute-optimized instance featuring 36 dedicated vCPUs from an Intel Xeon E5-2666 v3 processor running at 2.9 GHz. Built on the Xen hypervisor, it provides 60.0 GB of system memory, or 1.67 GB per core, but lacks local storage and GPU hardware. Network performance is anchored by a 10 Gbps baseline bandwidth. Benchmark data shows average performance across standard compute tasks, with a Geekbench multi-core score of 10598.0 and a Redis SET throughput of 30.6 million operations per second. However, the instance exhibits weak performance in LLM text generation, making it less suitable for modern AI workloads. It is highly effective for traditional CPU-intensive tasks, including software compilation, static web serving, and multi-threaded data decompression.

      Workload Profiles

      1.46Score
      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.
