Context Before

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 $3.28to[[04_{k}nowledg{e}_{b}ase/MI400|MI4XX]][[04_{k}nowledg{e}_{b}ase/Hyperscaler|Hyperscaler]]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.

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.

Evidence

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

Context After

Helios memory costs are more likely to be passed through or re-priced by assemblers and therefore exhibit greater hikes in a memory upcycle. Therefore, we model lower memory price hikes for VR and GB compared to MI4XX below. Our MI400 rack assumptions reflect $8.70/GB[[04_{k}nowledg{e}_{b}ase/LPDDR|LPDDR]]pricingfor[[02_{c}ompanies/AMD|AMD]]versus$6.77/GB for Nvidia, embedding volume discount structures vs the market contract price of $10.63/GB but reflecting the slack of volume economics vs NVIDIA.

Our AI Memory Model ↗ expects significant increases in LPDDR5 and DDR5 contract prices into 2Q26 and beyond and we expect to make further revisions higher in total server capex.
