SAMSUNG LPDDR Series: Upgrade Path & 4-Model Selection List

Generational Route (Samsung LPDDR Series)

LPDDR4 → LPDDR4X → LPDDR5 → LPDDR5X are the mainstream iterations of mobile memory. Samsung's LPDDR series offers stable high yields and multiple capacity options in each generation, facilitating platform integration.

Key points for four product upgrades (Samsung LPDDR series)

• ‌K4F6E3S4HM-GFCL (LPDDR4-16Gb)‌                                                                                                                                                                                Replacing multiple 8Gb chips with a single 16Gb chip reduces the number of chips, simplifies the design and lowers costs. It is suitable for scenarios with high capacity requirements, such as smartphones and AI.

• K4UBE3D4AM-THCL (LPDDR4X-32Gb)
  Compared to LPDDR4 of the same capacity, it offers lower I/O voltage, resulting in lower temperature rise and longer battery life in mobile devices.

• K3LKBKB0BM-MGCP (LPDDR5-12Gb)
  This platform offers significantly higher bandwidth than the LPDDR4X platform, making it suitable for mid-range to high-end SoCs and delivering improved AI inference and imaging throughput.

• K3KL1L10GM-JGCT (LPDDR5X-16Gb)
  Compared to LPDDR5 of the same capacity, it offers higher frequencies and stronger link training, making it suitable for flagship and industrial high-speed vision systems.

Cost-Performance-Delivery Triangle (Samsung LPDDR Series)

• Cost: LPDDR4/4X have a mature price premium, and the Samsung LPDDR series offers outstanding price-performance in the 32Gb segment.

• Performance: LPDDR5/5X is clearly ahead;

• Delivery: Secure orders in advance during peak season to ensure dual supply.
  Recommendation: After evaluating the SoC support matrix, perform A/B testing of the Samsung LPDDR series against competing products based on target frame rate and power consumption.

Competitive Comparison (Samsung LPDDR Series)

Micron/Hynix have significant negotiating power in certain weeks; however, the Samsung LPDDR series offers a better overall TCO due to its stable batch sizes, extensive design resources, and application cases.

Application List and Implementation (Samsung LPDDR Series)

• AI Camera/Industrial Vision: K3KL1L10GM-JGCT.

• Mid-range mobile phone/edge AI: K3LKBKB0BM-MGCP.

• Battery-powered IoT/thin terminal: K4UBE3D4AM-THCL.
