## Summary

China’s memory maker CXMT announced it will begin manufacturing HBM3E, an advanced high‑bandwidth memory used in AI accelerators. The company expects early‑stage production yields of only 20% to 30%, a figure cited by Reuters sources.

CXMT says the performance of its HBM3E chips is close to that of SK Hynix’s previous‑generation HBM3 products, suggesting comparable speed and bandwidth for AI workloads. The move comes as demand for high‑performance memory grows alongside expanding AI processor deployments worldwide.

Analysts note that low initial yields could limit supply and keep prices elevated, potentially affecting AI hardware manufacturers that rely on large‑capacity memory. CXMT’s entry into the HBM3E market adds another source of competition to the memory ecosystem dominated by South Korean firms.

## Key points

- CXMT will begin production of HBM3E high‑bandwidth memory chips.
- Early production yields are projected at only 20% to 30%.
- HBM3E performance is reported to be similar to SK Hynix’s prior‑gen HBM3 chips.

## Why it matters

HBM3E memory is critical for AI accelerators; CXMT’s low‑yield start could tighten supply and influence pricing for AI hardware developers.
