Context Before

Below we share detailed numbers on cost of servers, storage, networking, etc as well as what Nvidia plans to do with Groq.

Evidence

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.

Context After

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.

② Atomic Claim

由於 chip TDP 相近，而且多數 operating costs 會隨 IT power requirements 變動，因此 VR Max-P 與 MI4XX 的 operating costs 大致相近。
