      Server Description

      A high-frequency bare-metal server combining dedicated forty-eight core processing, rapid DDR5 memory, and high-speed networking for demanding enterprise workloads.

      General PurposeCompute Optimized

      Amazon Web Services m8azn.metal-12xl is a bare-metal general-purpose server designed for high-performance workloads requiring dedicated hardware. Powered by an AMD EPYC 9R05 processor with 48 physical cores and 48 vCPUs operating at 5.0 GHz, this instance features 192.0 GB of DDR5 memory running at 6 GHz. It lacks local storage and GPUs, relying on its 100 Gbps baseline network bandwidth for storage and external communication. Benchmark results place this server in the top tier for CPU and memory performance, highlighted by a PassMark CPU score of 116,193.1 and a Redis SET throughput of 178.57 million operations per second. The server offers high resource density and qualitative cost efficiency for bare-metal deployments. It is highly suited for high-throughput database operations, static web serving, and CPU-based language model inference.

      Workload Profiles

      7.11Score
      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.
