      CPU and System Topology

      Server Description

      A high-density, 192-core arm64 compute instance delivering top-tier multi-threaded performance and high memory bandwidth for parallelized workloads.

      Compute Optimized

      Amazon Web Services c8g.48xlarge is a compute-optimized instance featuring 192 dedicated physical cores on the arm64 architecture. Powered by AWS Graviton ARMv9 Neoverse-V2 processors running at 2.7 GHz, it includes 384.0 GB of memory, yielding 2.0 GB per core. The instance operates on the Nitro hypervisor, lacks local storage and GPUs, and provides 50 Gbps baseline network bandwidth. Benchmarks show top-tier multi-core CPU performance, memory bandwidth, and static web serving throughput, alongside strong software compilation and database execution. Conversely, single-core performance and small-model LLM prompt processing are average to weak. This instance is suited for highly parallelized workloads, including software compilation, physics simulations, and high-throughput web serving.

      Workload Profiles

      11Score
      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.
