      Server Description

      A bare-metal, compute-optimized server featuring 128 vCPUs and high-speed networking for demanding multi-threaded and cryptographic workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6i.metal is a bare-metal, compute-optimized server powered by dedicated Intel Xeon 8375C processors. It features 128 vCPUs, 64 physical cores, and 256 GB of DDR4 memory, providing a 1:2 vCPU-to-RAM ratio. The x86_64 architecture supports AVX-512 and hardware-accelerated cryptography. While the instance lacks local storage and dedicated GPUs, it delivers a 50 Gbps baseline network bandwidth. Benchmark results show top-tier performance in ray tracing, image processing, and Passmark CPU tests, alongside strong multi-core and memory bandwidth capabilities. Single-core performance and text generation speeds fall into the average range. This bare-metal configuration is designed for high-density, multi-threaded workloads such as software compilation, cryptographic operations, static web serving, and parallelized database tasks that benefit from direct hardware access without virtualization overhead.

      Workload Profiles

      4.65Score
      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.
