      Server Description

      A dedicated single-core Intel Xeon instance with DDR5 memory and advanced matrix extensions for lightweight compute workloads.

      Compute Optimized

      Amazon Web Services c8ib.large is a compute-optimized instance featuring a dedicated Intel Xeon 6975P-C processor running at 3.9 GHz. Built on the x86_64 architecture and managed by the Nitro hypervisor, it provides 2 vCPUs from a single physical core and is equipped with 4.0 GB of DDR5 memory. The processor includes a large 480 MB L3 cache and supports advanced instruction sets like AVX-512 and Intel AMX. While single-threaded performance is strong, as demonstrated by high gzip and bzip3 speeds, multi-core and memory bandwidth benchmarks are relatively weak due to the single-core hardware constraint. The instance does not include local storage or GPU accelerators, and features a baseline network bandwidth of 2 Gbps. It is best suited for lightweight, single-threaded compute tasks, basic web serving, and workloads utilizing specialized Intel instruction sets.

      Workload Profiles

      0.3Score
      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.
