      Server Description

      A high-density, memory-optimized ARM64 platform with 192 dedicated cores and three terabytes of RAM for massive parallel workloads.

      Memory OptimizedCompute Optimized

      The Amazon Web Services x8g.48xlarge is a memory-optimized instance featuring 192 dedicated physical cores powered by the ARM64 AWS Neoverse-V2 processor running at 2.7 GHz. Built on the Nitro hypervisor, this server is equipped with 3072.0 GB of RAM, yielding a high resource density of 16.0 GB per core. It lacks local storage and GPU accelerators but provides a baseline network bandwidth of 50 Gbps. Benchmark results demonstrate top-tier multi-core CPU performance, exceptional memory bandwidth, and superior database and Redis operation throughput. Conversely, single-core performance remains average. This hardware profile delivers qualitative cost efficiency for memory-intensive, highly parallelized applications. It is highly recommended for large-scale in-memory databases, distributed caching layers, and high-throughput enterprise workloads.

      Workload Profiles

      10.8Score
      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.
