      Server Description

      A dedicated AMD EPYC general-purpose instance featuring high-speed DDR5 memory and top-tier multi-core processing performance for enterprise workloads.

      General Purpose

      Amazon Web Services m8a.12xlarge is a general-purpose server featuring 48 dedicated AMD EPYC 9R45 physical cores and vCPUs running at 4.5 GHz on the Nitro hypervisor. It is equipped with 192.0 GB of DDR5 memory at 6 GHz, yielding 4.0 GB per core, but lacks local storage and dedicated GPUs. The instance delivers top-tier performance in CPU and memory benchmarks, ranking in the top 10% for stress-ng multi-core, Geekbench, and static web serving throughput. It supports advanced instruction sets like AVX-512 and SHA_NI, which assist in cryptographic and database operations. With a baseline network bandwidth of 22 Gbps and no local storage, it relies on network-attached storage. This hardware profile is suited for database operations, software compilation, static web serving, and CPU-based LLM inference.

      Workload Profiles

      5.44Score
      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.
