CXMT to begin limited HBM3E production with 20–30% yields

AIChina's CXMT will start limited HBM3E production in two months to ease the domestic AI memory shortage. The post says yields are only 20–30%, against about 70% at SK Hynix, and speed is close to older HBM3, more than one generation behind South Korean rivals ramping HBM4.

China's CXMT will start a limited HBM3E production in 2 months to ease domestic AI memory crunch. But this is at a cost:

• Yield: Just 20–30% (vs. SK Hynix's ~70%)

• Speed: Close to older HBM3

• Gap: 1+ gen behind as South Korean rivals ramp HBM4

Brute-forcing AI chips while discarding over 70% of production.
