Context Before
For 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;
Evidence
rack assemblers/ODMs source and integrate DDR5 memory.
Context After
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.
② Atomic Claim
rack assemblers / ODMs 會自行採購並整合 DDR5 memory。
