      Server Description

      An ARM64 general-purpose server delivering high memory bandwidth and strong multi-core performance for database and web serving workloads.

      General PurposeCompute Optimized

      Amazon Web Services m8gb.12xlarge is an ARM64 general-purpose server featuring 48 dedicated physical cores on the AWS Graviton Neoverse-V2 architecture running at 2.8 GHz. It is equipped with 192.0 GB of RAM (4.0 GB per core) and a 100 Gbps baseline network interface, though it lacks local storage and GPU hardware. Benchmarks show top-tier capabilities in memory bandwidth, multi-threaded bzip3 decompression, and database operations, alongside strong Geekbench multi-core scores. Conversely, single-core performance and small-model LLM text generation are weaker, representing a clear tradeoff. This hardware profile is optimized for multi-threaded workloads, software compilation, database management, and static web serving.

      Workload Profiles

      3.51Score
      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.
