      Server Description

      A 64-vCPU general-purpose instance featuring 256 GB RAM and 20 Gbps network bandwidth for parallelized multi-core server workloads.

      General Purpose

      Amazon Web Services m5.16xlarge is a general-purpose virtual instance based on the AWS Nitro system. Powered by an Intel Xeon 8175M processor running at 3.1 GHz, it features 32 physical cores and 64 vCPUs, paired with 256 GB of DDR4 memory and a 20 Gbps baseline network interface. The instance includes no local storage. Benchmark results show strong uncached large-block memory read bandwidth alongside average multi-core CPU, compilation, and database operation scores. Single-core performance and single-threaded data compression benchmark in the lower quartile. The 1:4 vCPU-to-RAM ratio offers a balanced resource profile without GPU acceleration. The m5.16xlarge instance suits parallelized multi-threaded enterprise applications, static web serving, software compilation builds, and database operations where baseline networking and memory density are required.

      Workload Profiles

      2.1Score
      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.
