      Server Description

      An ARM64 memory-optimized instance featuring dedicated physical cores and top-tier memory bandwidth for memory-intensive enterprise workloads.

      Memory Optimized

      Amazon Web Services x8g.4xlarge is an ARM64 memory-optimized instance featuring 16 dedicated physical cores powered by the AWS Graviton Neoverse-V2 processor at 2.8 GHz. Operating on the Nitro hypervisor, it delivers 256.0 GB of RAM, translating to 16.0 GB per core, with a baseline network bandwidth of 8 Gbps and no local storage. Benchmark results place its memory performance in the top 10% tier, with strong uncached read and write memory bandwidths of 292.71 GB/sec and 124.24 GB/sec, respectively. It also demonstrates strong capabilities in database operations and text processing. However, it shows weaker performance in LLM inference tasks. This resource profile makes the x8g.4xlarge highly efficient for memory-intensive workloads, such as in-memory databases, caching systems, and data processing applications requiring substantial memory capacity relative to compute resources.

      Workload Profiles

      1.81Score
      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.
