AI workload suitability
LLM inference
Best suited to smaller checkpoints, compressed models or distributed configurations sized by the recommendation engine.
Fine-tuning and training
Designed for sustained accelerator workloads; training suitability depends on interconnect, precision and cluster topology.
Image, video and embeddings
FP16 acceleration supports common generative and vector workloads within the listed VRAM envelope.
Power and cooling
275 W published power requires chassis, airflow and power delivery for this exact form factor.
Multi-GPU use
PCIe is the recorded interconnect path; topology must still be validated at node level.
Software ecosystem
cuda, vllm, sglang, tensorrt-llm
