      Server Description

      A bare-metal, memory-optimized server featuring 192 dedicated AMD EPYC cores and 1.5 TB of high-speed DDR5 RAM for demanding enterprise workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services r7a.metal-48xl is a bare-metal, memory-optimized server featuring 192 dedicated physical cores powered by AMD EPYC 9R14 processors running at 3.7 GHz. Built on the x86_64 architecture, it includes 1536.0 GB of high-speed DDR5 memory at 5 GHz, yielding 8.0 GB of RAM per core. The server lacks local storage and dedicated GPUs, but provides a 50 Gbps baseline network bandwidth. Performance benchmarks place this instance in the top tier for multi-core CPU execution, memory bandwidth, and Redis SET operations, which reach 332.38 million operations per second. However, text generation for small language models is a notable bottleneck, scoring in the bottom 25%. This hardware profile is highly efficient for large-scale in-memory databases, software compilation, and high-throughput web serving workloads that require massive memory capacity and dedicated compute resources without local storage needs.

      Workload Profiles

      7.6Score
      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.
