VR NVL72 TCO: BoM and Power Budget Analysis - Line hint:
931
Context Before
Source: VR NVL72 Component BoM and Power Budget Model ↗
Evidence
The VR NVL72 is more expensive on a per-GPU capital cost basis, ~45% higher vs GB300s and ~14-15% higher vs the MI4XX given a higher server cost on a per GPU basis. This results in a higher Capital Cost of Ownership (TCO). For example VR NVL 72 Hyperscaler Arista has a capital cost of 2.86 per hour per GPU over a 4 year useful life. Our TCO Model runs on a 4y useful life for the purpose of calculating capital cost per hour to reflect a conservative business case, but most Neoclouds and Hyperscalers will use a 5-6y depreciation period and we think it is best to look at EBIT margins using this depreciation period. Our preferred yardstick is Project IRR, which is agnostic to the chosen depreciation period.
Context After
However, one advantage for Nvidia’s VR SOCAMM option is that NVIDIA directly procures memory, allowing them to negotiate long-term agreements, volume-preferential terms with memory suppliers and most importantly, VVIP pricing. We think this will shield end customers from spikes in memory costs as we outline in our AI server apocalypse note ↗, and is another example of how, as the Central Bank of AI ↗, Nvidia is effectively hedging DRAM prices for all of its customers.
By contrast, AMD is much more exposed to DRAM price increases as it has about double the amount of DRAM, with about 55 TB per rack of LPDDR5 and 55 TB per rack of DDR5. For the AMD’s Helios rack scale system, AMD sells the GPU/board and does procure the LPDDR5 memory, but it does not procure DDR5 DRAM for rack compute trays; rack assemblers/ODMs source and integrate DDR5 memory. This leaves buyers of AMD’s racks more exposed because AMD is only able to potentially “hedge” the LPDDR5 portion via long-term contracts leaving the DDR5 portion completely exposed. Having double the DRAM content also nearly doubles the overall exposure.
