据 X.PIN 报道,中国 CXMT 将在两个月内开始限量生产 HBM3E,以缓解国内 AI 内存紧缺。代价是良率仅 20-30%(SK Hynix 约 70%),速度接近较旧的 HBM3,且在韩国对手推进 HBM4 时落后一代以上,超过 70% 的产出会被废弃。

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.
