      Server Description

      A general-purpose x86_64 instance featuring dedicated AMD EPYC cores, high-speed DDR5 memory, and top-tier single-core processing capabilities.

      General Purpose

      Amazon Web Services m8a.4xlarge is a general-purpose instance featuring 16 dedicated physical cores and 16 vCPUs powered by an AMD EPYC 9R45 processor running at 4.5 GHz. It is configured with 64.0 GB of DDR5 memory at 6 GHz, yielding 4.0 GB of RAM per core, and operates on the Nitro hypervisor. The instance lacks local storage and GPU accelerators, relying on an 8 Gbps baseline network bandwidth. Benchmarks indicate top-tier single-core performance, single-threaded compression, and Geekbench scores, alongside strong static web serving and memory performance. Conversely, multi-core stress-ng and database operations perform at average levels. This resource configuration is suitable for general-purpose applications, static web serving, text and image processing, and small-scale language model inference.

      Workload Profiles

      2.41Score
      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.
