      Server Description

      A compute-optimized x86_64 server with 36 dedicated vCPUs, 72 GB DDR4 RAM, and high-frequency Intel Xeon processing for compute-heavy workloads.

      Compute Optimized

      Amazon Web Services c5.9xlarge is a compute-optimized instance featuring 36 vCPUs and 18 physical cores powered by an Intel Xeon 8124M processor running at 3.4 GHz. Built on the Nitro hypervisor, it includes 72.0 GB of DDR4 memory at 3 GHz, providing a 2.0 GB per vCPU ratio. The instance lacks local storage and GPU accelerators, relying on a 12 Gbps baseline network bandwidth. Benchmark results show average performance, with a PassMark CPU score of 30341.37 and a Geekbench multi-core score of 10571.0. It supports AVX and AVX-512F instruction sets, making it highly effective for compute-heavy tasks. This hardware profile is well-suited for workloads such as software compilation, ray tracing, static web serving, and high-throughput Redis operations, though the lack of local storage and moderate memory density are notable tradeoffs for data-heavy applications.

      Workload Profiles

      1.42Score
      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.
