      Server Description

      A dedicated 32-core AMD EPYC instance with DDR5 memory, delivering top-tier single-core performance and balanced resources for enterprise workloads.

      General PurposeCompute Optimized

      The Amazon Web Services m8a.8xlarge is a general-purpose instance featuring 32 dedicated physical cores and 32 vCPUs powered by an AMD EPYC 9R45 processor running at 4.5 GHz. It is equipped with 128.0 GB of 6 GHz DDR5 memory, delivering a balanced 1:4 vCPU-to-RAM ratio, but lacks local storage and dedicated GPUs. Running on the Nitro hypervisor, it provides a baseline network bandwidth of 15 Gbps. Benchmark data places the instance in the top 10% for single-core CPU performance, database operations, and small-model LLM inference, while multi-core operations and memory bandwidth rank in the top 25%. However, performance drops to average for large 70B LLM inference. This hardware profile makes the instance highly effective for database management, web serving, software compilation, and medium-scale data processing workloads where local storage is not a primary requirement.

      Workload Profiles

      4.2Score
      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.
