CPU and System Topology

Server Description

An accelerated virtual server combining dedicated AMD EPYC processors, local NVMe storage, and NVIDIA Ampere graphics for demanding machine learning workloads.

GPU AcceleratedGeneral Purpose

Amazon Web Services g5.16xlarge is a graphics-intensive instance featuring 64 dedicated vCPUs from an AMD EPYC 7R32 processor running at 3.3 GHz, 256.0 GB of DDR4 memory, and a baseline network bandwidth of 25 Gbps. It includes a bundled NVIDIA Ampere A10G GPU with 22 GB of VRAM and 1900 GB of local NVMe SSD storage. Performance benchmarks show a contrast between poor single-core CPU metrics and top-tier LLM inference speeds for small and medium models. While PassMark CPU and memory scores are strong, text generation for large 70B models is weak. This configuration offers qualitative cost efficiency by combining dedicated compute, high-speed local storage, and GPU acceleration on the Nitro hypervisor. It is best suited for machine learning inference, ray tracing, and workloads requiring high-density GPU and storage resources.

Workload Profiles

2.1Score
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.
