Context Before

Operating costs are similar for VR Max-P vs MI4XX given their comparable chip TDPs and given that most operating costs scale with respect to IT power requirements.
Evidence
VR Max-Q on the other hand, exhibits lower Operating costs relative to MI4XX given the lower chip TDP. For example a VR NVL 72 cluster deployed at a Hyperscaler with Arista networking would have a operating cost of $0.75 per gpu per hour, representing ~20% lower costs vs MI4XX deployed with a Hyperscaler with the same Arista networking. This highlights the advantages of the Max-Q configuration, particularly from an operating cost perspective, as the lower power TDP reduces rack-level power density for a meaningful cost savings over time.
