      Server Description

      A dedicated 64-core ARM64 compute instance delivering high multi-threaded throughput and memory bandwidth for parallelized workloads and web serving.

      Compute OptimizedGeneral Purpose

      The Amazon Web Services c6g.16xlarge is a compute-optimized server featuring 64 dedicated physical ARM64 cores powered by AWS Graviton2 Neoverse-N1 processors running at 2.5 GHz. Built on the AWS Nitro hypervisor, this instance provides 128.0 GB of system memory, a baseline network bandwidth of 25 Gbps, and contains no local storage or GPU hardware. Benchmarks reveal strong multi-core capabilities, particularly in software compilation, Redis operations, and static web serving, where it ranks in the top 25%. However, single-core performance and single-threaded compression tasks represent a relative tradeoff, scoring in the lower percentiles. This server is highly cost-efficient for highly parallelized, compute-intensive workloads such as distributed web serving, containerized microservices, and multi-threaded build pipelines that benefit from dedicated physical cores without hyperthreading overhead.

      Workload Profiles

      2.43Score
      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.
