      Server Description

      A high-bandwidth, sixty-four core ARM64 server delivering exceptional memory throughput and multi-threaded performance for parallelized enterprise workloads.

      General PurposeCompute Optimized

      Amazon Web Services m8gn.16xlarge is a general-purpose, network-optimized instance featuring 64 dedicated physical ARMv9 cores powered by AWS Neoverse-V2 processors running at 2.8 GHz. Equipped with 256.0 GB of system memory and a 200 Gbps baseline network interface, this Nitro-based server lacks local storage and GPU accelerators. Benchmarks highlight top-tier multi-core efficiency, exceptional memory bandwidth, and superior database throughput, with Redis SET operations reaching 140.57 million operations per second. While single-core performance is average, its highly parallelized architecture offers excellent qualitative cost efficiency for multi-threaded workloads. It is best suited for high-throughput web serving, software compilation, and database operations.

      Workload Profiles

      4.3Score
      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.
