      Server Description

      A bare-metal, ninety-six core compute-optimized platform delivering top-tier processor performance and high-speed memory bandwidth for demanding enterprise workloads.

      Compute Optimized

      Amazon Web Services c8a.metal-24xl is a bare-metal, compute-optimized server powered by a 96-core AMD EPYC 9R45 processor running at 4.5 GHz. Utilizing the x86_64 architecture with a dedicated CPU allocation, it features 192.0 GB of system memory, translating to 2.0 GB of RAM per core. The instance does not include local storage or GPUs, but provides a 40 Gbps baseline network bandwidth. Benchmark data ranks this server in the top tier for single-core and multi-core CPU performance, memory bandwidth, and cryptographic operations. It supports advanced instruction sets such as AVX-512 and bfloat16, facilitating rapid execution of complex mathematical tasks. The c8a.metal-24xl is highly suited for compute-intensive workloads, including software compilation, static web serving, database operations, and large language model inference.

      Workload Profiles

      8.16Score
      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.
