      Server Description

      A compute-optimized instance featuring high-frequency Intel Xeon processors and DDR5 memory for single-threaded and text-processing workloads.

      Compute Optimized

      Amazon Web Services c8i.xlarge is a compute-optimized instance utilizing the Nitro hypervisor and an Intel Xeon 6975P-C processor. Operating on the x86_64 architecture, it provides 4 dedicated vCPUs running at 3.9 GHz, supported by a 480 MB L3 cache and 8.0 GB of DDR5 memory. The instance lacks local storage and GPUs, relying on a 2 Gbps baseline network bandwidth. Benchmarks highlight exceptional single-core and text-processing capabilities, alongside strong single-threaded compression performance, though multi-core and cached memory bandwidth results are weaker. With advanced instruction support like AVX-512 and Intel AMX, the c8i.xlarge represents a cost-efficient profile for compute-heavy, single-threaded tasks, text processing, and web serving, while its 1:2 vCPU-to-RAM ratio makes it less suitable for memory-intensive workloads.

      Workload Profiles

      0.538Score
      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.
