Context Before

VR Max-Q on the other hand, exhibits lower Operating costs relative to MI4XX given the lower chip TDP.

Evidence

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.

Context After

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.

② Atomic Claim

例如，採用 Arista networking 的 VR NVL72 Hyperscaler cluster，operating cost 約為每顆 GPU 每小時 0.75 美元，比採用相同 Arista networking 的 MI4XX 約低 20%。
