      Server Description

      A compute-optimized x86 server offering 32 vCPUs, DDR5 memory, Intel AMX instruction support, and high single-threaded data compression throughput.

      Compute OptimizedGeneral Purpose

      Amazon Web Services c7i-flex.8xlarge is a compute-optimized instance driven by a 3.2 GHz Intel Xeon 8488C processor featuring 32 dedicated vCPUs across 16 physical cores, 64.0 GB of DDR5 memory, and a 6 Gbps baseline network bandwidth. Built on the AWS Nitro hypervisor without local SSD storage or GPU acceleration, the server incorporates 105 MB of L3 cache, AVX-512, and Intel Advanced Matrix Extensions (AMX). Performance testing highlights strong single-core efficiency, with top-tier results in gzip compression (33.6 GB/sec), static web serving throughput (51.12 GB/sec), and text processing benchmarks. Multi-threaded CPU execution and uncached DDR5 memory bandwidth perform in the average tier. The instance provides cost efficiency through flexible resource scaling, making it well suited for web serving, data compression pipelines, software build compiling, and small-model machine learning inference.

      Workload Profiles

      2.3Score
      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.
