      Server Description

      A high-density ARM64 compute instance featuring 192 dedicated physical cores and 300 Gbps network bandwidth for parallelized workloads.

      Compute OptimizedStorage & Database

      Amazon Web Services c8gn.48xlarge is a compute-optimized, network-optimized instance featuring 192 dedicated ARMv9 Neoverse-V2 physical cores running at 2.7 GHz. Equipped with 384.0 GB of memory (2.0 GB per core) and a 300 Gbps network interface, this instance lacks local storage and GPU accelerators. Benchmarks indicate top-tier performance in multi-core processing, memory bandwidth, software compilation, and Redis database operations, though single-core performance and small-model LLM prompt processing represent notable tradeoffs. The instance delivers high resource density and qualitative cost efficiency for parallelized, network-heavy workloads. It is highly suited for static web serving, database operations, and multi-threaded compilation tasks.

      Workload Profiles

      10Score
      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.
