GB200 GB300液冷价值量拆解

Core Viewpoint - The article focuses on the delivery and value breakdown of liquid cooling systems in NVIDIA's GB200 and GB300 server racks, highlighting the differences in design and component value between the two models [2]. Liquid Cooling Server Rack Components - The liquid cooling server rack includes several key components such as manifolds, cooling distribution units (CDUs), pumps, water tanks, plate heat exchangers, and cooling towers [5][6][8][9]. Value Breakdown of Liquid Cooling - The article emphasizes the importance of understanding the architecture of GB200 to facilitate the value breakdown analysis [21]. - For GB200, the demand for large cold plates is 45 units, while GB300 requires 117 units of small cold plates [22]. - The value of a large cold plate in GB200 is $650, whereas a small cold plate in GB300 is valued at $240 [23]. Supplier Dynamics - The supplier landscape for cold plates has shifted significantly from GB200 to GB300, with Cooler Master becoming the primary supplier for GB300, capturing over 55% of the market share [24][25]. - The production process for GB300's liquid cooling plates involves more integration steps compared to GB200, indicating a more complex supply chain [25]. Component Pricing - The price of hoses for GB200 is $1,200 per cabinet, while for GB300, it has increased to between $1,800 and $2,000 per cabinet [26]. - The price of quick disconnects (QDs) has also increased from $45 per pair in GB200 to $55 per pair in GB300 [28]. Technological Upgrades - The quick disconnect technology has evolved from UQD in GB200 to NVUQD in GB300, with a significant change in the supplier base, reducing the share of European and American companies [29]. - The CDU supplier model has transitioned from a single authorized supplier for GB200 to a more diversified supplier base for GB300, enhancing market responsiveness [30]. Profit Margins - The gross margin for CDUs is approximately over 50%, while for cold plates, manifolds, and quick disconnects, it is around 30% [30].
