PCIe 5.0 x8 vs x16 performance for dual RTX 6000 Ada GPUs debated

By PulseAugur Editorial · [1 sources] ·

A user on Reddit's r/LocalLLaMA subreddit is seeking advice on the performance impact of running two RTX 6000 Ada Generation GPUs in a PCIe 5.0 x8 configuration versus a PCIe 5.0 x16 configuration. The user's current Asus ROG MAXIMUS Z790 motherboard limits dual GPUs to x8 lanes, and upgrading to a Threadripper PRO system for x16 lanes would be significantly more expensive. They are concerned about the performance difference for tasks like AI inference using vLLM, graphic generation, and LoRA training. AI
