      Server Description

      A bare-metal arm64 platform delivering three terabytes of DDR5 memory and one hundred ninety-two dedicated cores for massive parallel workloads.

      Memory OptimizedCompute Optimized

      Amazon Web Services x8g.metal-48xl is a bare-metal, memory-optimized server featuring 192 dedicated arm64 physical cores powered by AWS Graviton Neoverse-V2 processors running at 2.7 GHz. Equipped with 3072.0 GB of DDR5 memory, it provides a high memory-to-core ratio of 16.0 GB per core. The server lacks local storage and GPUs but delivers a baseline network bandwidth of 50 Gbps. Benchmark data indicates top-tier multi-core CPU and memory bandwidth performance, alongside outstanding database and static web serving throughput. However, single-core performance and LLM text generation speeds are average to poor. This instance is highly cost-efficient for memory-intensive, highly parallel workloads, making it an excellent fit for large-scale in-memory databases, high-throughput web serving, and intensive software compilation tasks.

      Workload Profiles

      10Score
      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.
