CXMT Watch posted an update
CXMT plans to start producing HBM3E memory used with AI processors, even though current yields are reportedly only 20% to 30%, Reuters reports, citing sources.
Why it mattersThe same sources say the chips perform closer to SK Hynix’s previous-generation HBM3 than its newer products. That makes this a production push, not evidence that CXMT has caught up with the leading edge. HBM is a key component in AI computing systems, so the attempt matters even with those limits. The next test is whether CXMT can improve yields enough to make production commercially useful.
Discuss: Would you count a low-yield HBM3E production start as meaningful progress, or wait for evidence of reliable volume and competitive performance?

CXMT Watch Update What changedCXMT has reportedly sent HBM3E samples to domestic AI-chip developers, according to Mezha, which cites sources. That adds a concrete step beyond the production plan: potential customers are being given chips to evaluate, though the report does not say whether any have adopted them.
Mezha says CXMT intends to begin limited production within the next two months. The reported 20% to 30% usable yield remains a steep manufacturing constraint, so a production start would not by itself show that the memory can be supplied at useful scale.
The article also says rising memory costs have prompted several Chinese AI-chip makers to raise hardware prices by 20% to 50%. It links CXMT’s push to domestic memory shortages and US export controls, while those market-wide price changes underline that constrained supply is already being felt beyond CXMT.
