      Server Description

      An arm64 compute-optimized instance featuring dedicated physical cores and top-tier memory bandwidth for efficient, high-throughput processing workloads.

      Compute Optimized

      Amazon Web Services c8g.4xlarge is an arm64 compute-optimized instance powered by a 2.8 GHz AWS Graviton processor with 16 dedicated physical cores and 16 vCPUs. It features 32.0 GB of memory, yielding 2.0 GB per core, and operates on the AWS Nitro hypervisor with an 8 Gbps baseline network speed. The instance lacks local storage and GPU accelerators. Benchmark results show top-tier memory performance, with Passmark memory scores in the top 10% and uncached large-block read bandwidth reaching 302.31 GB/sec. Geekbench single-core and multi-core metrics also place in the top 25%. However, prompt processing for medium LLMs is a relative weakness, scoring in the bottom 25%. This instance offers qualitative cost efficiency for compute-bound tasks with moderate memory requirements, making it suitable for software compilation, text processing, database operations, and web serving.

      Workload Profiles

      1.77Score
      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.
