      Server Description

      A compute-optimized x86_64 server featuring 64 vCPUs, DDR5 memory, and advanced matrix extensions for high-density processing workloads.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7i.16xlarge is a compute-optimized instance featuring 64 vCPUs and 32 physical cores powered by an Intel Xeon 8488C processor at 3.2 GHz. It is equipped with 128.0 GB of DDR5 memory at 5 GHz, providing 2.0 GB of RAM per core, and operates on the Nitro hypervisor. The instance lacks local storage and GPUs, but offers a 25 Gbps baseline network bandwidth. Benchmarks indicate strong performance in multi-core processing, software compilation, cryptography, and database operations, placing it in the top 25 percent. It also performs well in LLM inference for small and medium models due to built-in AMX and AVX-512 instruction support. This instance is appropriate for compute-intensive workloads, including web serving, software compilation, and database management, where high CPU density is prioritized over large memory allocations.

      Workload Profiles

      3.38Score
      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.
