      CPU and System Topology

      Server Description

      A dedicated AMD EPYC compute-optimized instance delivering strong single-core performance for processing-heavy workloads without local storage requirements.

      Compute Optimized

      Amazon Web Services c6a.2xlarge is an x86_64 compute-optimized instance powered by an AMD EPYC 7R13 processor running at 3.6 GHz. It features 8 dedicated vCPUs across 4 physical cores, 16.0 GB of DDR4 memory, and a baseline network bandwidth of 3 Gbps, with no local storage or GPUs. Performance benchmarks show strong single-core CPU execution, though multi-core performance and cryptographic operations remain average. A key hardware tradeoff is its memory bandwidth, as large-block uncached reads and writes perform in the bottom 25%. This instance is qualitatively cost-effective for compute-heavy workloads that do not depend on high memory throughput. It is suited for software compilation, static web serving, and general compute tasks.

      Workload Profiles

      0.486Score
      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.
