- It delivers at least 50% more die output per wafer, which is expected to significantly improve cost-effectiveness and power efficiency.
Alongside the platform launch, CXMT also introduced two new 24Gb LPDDR5X products that are now in mass production. These chips are specifically targeting China’s domestic market for flagship smartphones.
