      Server Description

      An ARM64 general-purpose instance featuring dedicated physical cores, high memory bandwidth, and balanced resource allocation for database and application workloads.

      General Purpose

      Amazon Web Services m8gb.4xlarge is a general-purpose ARM64 server powered by an AWS Graviton ARMv9 Neoverse-V2 processor. Operating on the Nitro hypervisor, it features 16 dedicated physical cores running at 2.8 GHz and 64.0 GB of RAM, yielding 4.0 GB of memory per core. The instance lacks local storage and GPUs but provides a baseline network bandwidth of 33 Gbps. Performance benchmarks highlight top-tier memory performance and strong large-block memory bandwidth, alongside strong database operations and multi-threaded decompression capabilities. General compute and web serving metrics remain in the average tier, while LLM inference performance is relatively weak. This resource profile offers qualitative cost efficiency through dedicated physical cores on an ARM architecture, making it highly suitable for database hosting, multi-threaded data processing, and general-purpose application serving.

      Workload Profiles

      1.58Score
      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.
