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; 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.

Evidence

Having double the DRAM content also nearly doubles the overall exposure.

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.

② Atomic Claim

DRAM content 約為兩倍，也使整體 memory price exposure 幾乎倍增。
