      Server Description

      A balanced x86_64 compute and memory profile featuring 64 vCPUs and strong large-block memory read bandwidth for multi-threaded workloads.

      General Purpose

      Amazon Web Services m5.16xlarge is a general-purpose instance featuring 64 vCPUs and 256.0 GB of DDR4 RAM, powered by an Intel Xeon 8175M processor at 3.1 GHz on the Nitro hypervisor. It lacks local storage and GPUs but provides a 20 Gbps baseline network bandwidth. Benchmarks reveal weak single-core performance but average multi-core and database execution capabilities, alongside strong large-block read-only memory bandwidth of 192.72 GB/sec. This instance is suited for multi-threaded workloads, static web serving, and Redis deployments, though it presents a tradeoff in single-threaded efficiency.

      Workload Profiles

      2.16Score
      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.
