      Server Description

      A burstable general-purpose instance with 48 vCPUs, DDR5 memory, and high memory bandwidth for scalable web serving and database operations.

      General PurposeBurstable & Budget

      Amazon Web Services m7i-flex.12xlarge is a general-purpose instance featuring 48 vCPUs and 24 physical cores on an Intel Xeon 8488C processor running at 3.2 GHz under the AWS Nitro hypervisor. The hardware profile includes 192 GB of DDR5 memory at 5 GHz, providing 4 GB per vCPU, along with a 9 Gbps baseline network bandwidth. No local storage or discrete GPUs are attached. Built on a burstable CPU model, the instance yields cost efficiency for variable compute patterns. Benchmarks reflect strong memory bandwidth reaching 222.41 GB/sec for uncached reads, robust Redis throughput at 64.03 million SET operations per second, and high software compilation performance, alongside middle-tier CPU stress scores. It is suitable for web serving, database processing, compilation, and general backend workloads.

      Workload Profiles

      3.3Score
      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.
