Description

The Dell PowerEdge XE9685L is Dell's AMD-powered, no-compromise solution for the most intensive AI and HPC workloads. Housed in a dense 4U form factor, its most critical feature is the Direct Liquid Cooling (DLC) system, which efficiently cools the CPUs, the 8 high-wattage NVIDIA HGX SXM GPUs (such as the B200 or H200), and their high-speed NVLink interconnects

This thermal architecture enables sustained peak performance necessary for training large language models (LLMs) and executing complex simulations, driving 3x higher LLM training performance compared to previous generations. The dual AMD EPYC 9005 Series processors provide an enormous number of high-performance cores (up to 192 per CPU) to orchestrate data movement and parallel processing across the 8 GPUs. The XE9685L is foundational for deploying a dense, energy-efficient, and future-ready "AI Factory" infrastructure.
