      CPU and System Topology

      Server Description

      A high-density memory-optimized instance featuring 192 vCPUs and 3 TB of DDR5 RAM for demanding in-memory database workloads.

      Memory OptimizedCompute OptimizedStorage & Database

      Amazon Web Services x8i.48xlarge is a memory-optimized server instance utilizing the AWS Nitro hypervisor. It is equipped with an Intel Xeon 6975P-C processor offering 192 vCPUs (96 physical cores) at 3.9 GHz, alongside 3072.0 GB of DDR5 memory running at 7 GHz. The architecture supports advanced vector and matrix extensions (AVX-512 and AMX). Benchmark results place this instance in the top 10% for multi-core CPU performance, large-block memory bandwidth, and database operations, including Redis SET performance. However, it lacks local storage and dedicated GPUs, relying entirely on network-attached storage and baseline network bandwidth of 75 Gbps. This high-density memory configuration is designed for large-scale in-memory databases, enterprise applications, and CPU-based LLM inference.

      Workload Profiles

      9.13Score
      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.
