      Server Description

      An x86_64 compute-optimized virtual machine featuring dedicated Intel Xeon processors and DDR5 memory for single-threaded and text-processing workloads.

      Compute Optimized

      Amazon Web Services c8i-flex.2xlarge is an x86_64 compute-optimized instance featuring an Intel Xeon 6975P-C processor running at 3.9 GHz. It delivers 8 dedicated vCPUs across 4 physical cores, paired with 16.0 GB of DDR5 memory at 7 GHz, but lacks local storage and GPU accelerators. Built on the Nitro hypervisor, the instance demonstrates strong single-threaded capabilities, highlighted by a Geekbench single-core score of 2157.0 and top-tier text processing performance. However, multi-core benchmarks and medium-model LLM text generation are average to weak, and network bandwidth is limited to a baseline of 2 Gbps. This instance is suited for compute-intensive workloads such as text processing, software compilation, and static web serving where high memory-to-CPU ratios and local storage are not required.

      Workload Profiles

      0.97Score
      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.
