Recent reports from the Computex tech conference have overturned a major market expectation: Chinese memory manufacturer CXMT is not selling its DDR5 memory at a discount.
The primary reason for this surprising development is the ongoing AI supercycle. The world's largest memory producers—Samsung, SK hynix, and Micron—are dedicating a significant portion of their manufacturing capacity to producing High Bandwidth Memory (HBM). HBM is a specialized, high-performance memory essential for AI chips, and it commands much higher prices and profits. The catch is that producing HBM consumes far more silicon wafer space than standard DDR5 memory.
This creates a clear cause-and-effect chain. First, intense AI demand pushes manufacturers to prioritize HBM production. Second, this strategic shift diverts resources away from standard DDR5, leading to a tighter supply. Third, with less DDR5 available, prices naturally remain firm. In this environment, it doesn't make financial sense for a new entrant like CXMT to start a price war. Instead, their key advantage is simply having DDR5 available to sell to clients when others are focused on HBM.
Two other factors reinforce this situation. Technologically, CXMT still lags behind in the most advanced and profitable server memory formats, such as MRDIMM and CUDIMM. This limits its ability to compete in the high-end market where pricing power is strongest. Furthermore, the U.S. government is finalizing rules that would bar federal agencies from purchasing products containing CXMT chips. This regulatory risk makes Western companies hesitant to rely on CXMT, reducing the incentive for the Chinese firm to slash prices to gain global market share.
In short, the narrative of "cheap Chinese DDR5" flooding the market appears to be a myth for the time being. The market's dynamics are currently dictated by HBM-driven supply constraints. CXMT's role is to provide additional DDR5 supply, primarily within its domestic market, rather than to trigger a global price collapse.
