The bill of materials for HBM4 memory on a single Nvidia Rubin GPU is estimated at approximately 720,000 yen, potentially driving the total unit cost to 10 million yen.
Context
Nvidia is advancing its next-generation Rubin architecture, with estimates suggesting that HBM4 memory components alone will cost approximately 720,000 yen (roughly $4,700) per unit. This sharp increase in the bill of materials reflects the technical complexity of the 12-layer and 16-layer memory stacks required for future AI scaling. Consequently, the projected market price for a single Rubin GPU could reach 10 million yen (approx. $65,000), positioning it as a high-premium successor to the Blackwell series.
The escalating production costs highlight the tightening global supply chain for high-performance memory. For investors, the financial scale is massive, as a deployment of 100,000 units represents a 1 trillion yen (approx. $6.5 billion) investment. While rising costs could pressure hardware margins, Nvidia is betting on unparalleled performance to sustain its pricing power when the Rubin platform enters mass production, currently anticipated for 2026.
