      Server Description

      A bare-metal, 64-core ARM-based server delivering high multi-threaded efficiency and dedicated compute resources for high-concurrency workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c6g.metal is a bare-metal, compute-optimized server featuring 64 dedicated physical cores on the arm64 AWS Graviton2 processor. Operating at 2.5 GHz, it is equipped with 128.0 GB of DDR4 memory and a 25 Gbps baseline network interface, with no local storage or GPU accelerators. Benchmarks reveal strong multi-core performance, particularly in software compilation, Redis operations, and static web serving, alongside average single-core and large-block memory bandwidth metrics. The lack of hypervisor overhead provides high resource density and efficiency for multi-threaded workloads. This server is highly suited for high-concurrency web serving, CI/CD compilation pipelines, and distributed caching systems.

      Workload Profiles

      2.38Score
      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.
