      Server Description

      An arm64 compute-optimized instance featuring dedicated ARMv9 cores and strong single-core performance for compute-intensive workloads without local storage requirements.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c8gb.2xlarge is a compute-optimized instance featuring 8 dedicated physical cores on an arm64 AWS Graviton ARMv9 Neoverse-V2 processor running at 2.8 GHz. It is configured with 16.0 GB of memory, yielding 2.0 GB per core, and operates on the Nitro hypervisor with a baseline network bandwidth of 17 Gbps. The instance lacks local storage and GPU accelerators. Performance benchmarks show strong single-core capabilities, including a Geekbench single-core score of 1890.0 and a bzip3 single-threaded decompression rate of 14.48 GB/sec. However, cryptographic performance is a notable tradeoff, with the Passmark encryption test scoring in the bottom 25%. This instance is suited for workloads such as software compilation, static web serving, and lightweight single-threaded processing tasks that benefit from dedicated ARMv9 cores but do not require local SSD storage.

      Workload Profiles

      0.913Score
      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.
