      Server Description

      A high-density, 192-core arm64 compute instance delivering exceptional multi-threaded performance and high-bandwidth networking for parallel workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c8gb.48xlarge is a compute-optimized server instance powered by 192 dedicated physical cores on the arm64 AWS Graviton ARMv9 Neoverse-V2 architecture. Operating at 2.7 GHz on the Nitro hypervisor, it features 384.0 GB of system memory (2.0 GB per core) and a 200 Gbps baseline network bandwidth, with no bundled local storage or GPUs. Benchmarks highlight top-tier multi-core CPU performance, exceptional memory bandwidth, and superior database operations, while single-core performance remains average. This resource profile makes the instance highly efficient for highly parallelized workloads, software compilation, high-throughput static web serving, and database operations, though it requires network-attached storage for persistent data.

      Workload Profiles

      9.5Score
      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.
