      Server Description

      A high-density compute instance featuring 192 vCPUs, 100 Gbps networking, and top-tier multi-core performance for demanding parallel workloads.

      General PurposeCompute Optimized

      Amazon Web Services inf2.48xlarge is an Inferentia Gen2 instance featuring 192 vCPUs and 96 physical cores powered by an AMD EPYC 7R13 processor running at 3.6 GHz. Built on the AWS Nitro hypervisor, it includes 768.0 GB of DDR4 memory and a 100 Gbps baseline network interface, with no local storage. The instance delivers top-tier multi-core CPU performance, ranking in the top 10% on stress-ng and PassMark CPU tests, alongside strong cached memory bandwidth and high-throughput Redis SET operations. However, its PassMark memory score is in the bottom 10%. The inf2.48xlarge is highly effective for multi-threaded compute tasks, software compilation, ray tracing, and high-bandwidth network services, though storage-dependent workloads must rely on network-attached volumes.

      Workload Profiles

      4.45Score
      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.
