CXMT plans limited HBM3E production at 20–30% yields, per X post

China's CXMT will start limited HBM3E production in about two months to ease China's domestic AI memory shortage, according to an X post by @thexpin.

The post says the yields are only 20–30%, compared with about 70% at SK Hynix, and that the chips' speed is close to older HBM3. It also says South Korean rivals are ramping HBM4, more than one generation ahead.

The report is a single unverified social media post. It names no official source from CXMT or any other company, and it gives no production volumes.
