      Server Description

      A bare-metal platform featuring 192 dedicated AMD EPYC cores and DDR5 memory for high-throughput parallel computing and database workloads.

      General PurposeCompute Optimized

      Amazon Web Services m8a.metal-48xl is a general-purpose bare-metal server featuring 192 dedicated AMD EPYC 9R45 physical cores operating at 4.5 GHz. It is configured with 768.0 GB of DDR5 memory at 6 GHz, offering a balanced 4.0 GB of RAM per core, but lacks local storage and GPU hardware. The server delivers top-tier performance, ranking in the top 10% for multi-core CPU benchmarks, memory bandwidth, and database operations. Network connectivity is supported by a 75 Gbps baseline bandwidth. While the lack of local NVMe storage represents a key architectural tradeoff, the bare-metal design eliminates hypervisor overhead, making it highly efficient for massive parallel processing, software compilation, static web serving, and large-scale database workloads.

      Workload Profiles

      13.6Score
      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.
