      Server Description

      An arm64 compute-optimized server featuring 48 dedicated cores and top-tier memory bandwidth for highly parallelized workloads.

      Compute Optimized

      Amazon Web Services c8g.12xlarge is an arm64 compute-optimized instance powered by the AWS Graviton Neoverse-V2 processor. It features 48 dedicated physical cores and 48 vCPUs running at 2.8 GHz, paired with 96.0 GB of RAM, and operates on the Nitro hypervisor. The instance lacks local storage and GPU accelerators but delivers a baseline network bandwidth of 22 Gbps. Benchmark results indicate top-tier performance in multi-core processing, software compilation, and memory bandwidth, alongside strong database and static web serving capabilities. Conversely, single-core performance and cryptographic operations align with average tiers. This hardware profile offers high resource density and qualitative cost efficiency for parallelized tasks. It is highly suitable for workloads such as software compilation, multi-threaded decompression, database operations, and static web serving.

      Workload Profiles

      3.9Score
      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.
