AI workload suitability

LLM inference

High memory capacity supports large checkpoints and multi-GPU inference when runtime and topology are certified.

Fine-tuning and training

Suitable for limited fine-tuning and development when software support, cooling and memory capacity are verified.

Image, video and embeddings

FP16 acceleration supports common generative and vector workloads within the listed VRAM envelope.

Power and cooling

The manufacturer does not publish a directly comparable board-power value for this entity.

Multi-GPU use

NVLink 5 is the recorded interconnect path; topology must still be validated at node level.

Software ecosystem

cuda, vllm, sglang, tensorrt-llm
