Context Before
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.
Evidence
Context After
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.
NVIDIA’s 2300W configuration represents the Max-P configuration, while the efficiency optimized Max-Q configuration runs at 1800W. Regardless of which configuration Nvidia claims both can hit the same peak clocks and therefore achieve marketed 50 PFLOPS FP4 performance. While the underlying hardware is the same, the TCO implications are due to operating costs from different levels of power consumption.
② Atomic Claim
SemiAnalysis 對 MI400 rack 的假設,AMD LPDDR pricing 為 8.70 美元/GB,Nvidia 則為 6.77 美元/GB;兩者都低於 market contract price 10.63 美元/GB,但反映 NVIDIA 在 volume economics 上更有優勢。
