      Server Description

      A bare-metal server combining high-frequency dedicated processors with high-speed network bandwidth for demanding, network-intensive workloads.

      General PurposeCompute Optimized

      Amazon Web Services m5zn.metal is a bare-metal, general-purpose server featuring a dedicated Intel Xeon 8252C processor with 24 physical cores, 48 vCPUs, and a high clock speed of 4.5 GHz. It is equipped with 192.0 GB of DDR4 memory, providing 4.0 GB of RAM per core, and offers a baseline network bandwidth of 100 Gbps without local storage or integrated GPUs. Benchmarks show top-tier memory performance and strong large-block memory bandwidth, alongside average CPU and database performance. However, LLM text generation speeds represent a performance tradeoff, rating as weak to poor. Given its high-frequency dedicated cores and optimized network capabilities, this server is well-suited for network-intensive applications, software compilation, and database workloads relying on network-attached storage.

      Workload Profiles

      2.6Score
      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.
