[News] Samsung’s LPDDR6 Passes Industry-First Snapdragon Validation; Galaxy S27 May Split Memory Tiers

As Qualcomm’s Snapdragon Summit kicks off on September 22, Samsung is marking a mobile memory milestone of its own. The company says it has become the first to validate LPDDR6 on the Snapdragon 8 Elite Extreme Gen 6, reaching speeds of up to 10.7 Gbps while improving power efficiency by as much as 21% over LPDDR5X, according to Chosun Biz.

According to Samsung, its 16GB LPDDR6 completed validation on Qualcomm’s latest Snapdragon platform. As explained by ZDNet, LPDDR6 offers bandwidth of 10.6–14.4 Gbps, a significant improvement over the previous generation’s 8.5–10.7 Gbps.

Asia Business Daily highlights that Samsung’s ties with leading mobile AP makers stretch back several generations. After qualifying LPDDR5X on Qualcomm’s Snapdragon platform in 2022, the memory giant achieved an industry first in 2024 with 10.7Gbps LPDDR5X on MediaTek’s flagship Dimensity 9400, the report adds.

It is also worth noting that China’s DRAM leader, CXMT, announced earlier this month the official mass production of LPDDR6. According to TechPowerUp, CXMT’s LPDDR6 is rated at up to 12.8 Gbps, stepping up from the standard 10.7 Gbps baseline. TechNews adds that Xiaomi has also confirmed that the 18 Fold will feature its in-house XRING O3 mobile processor, making it the first platform to support CXMT’s LPDDR6.

Galaxy S27 Could Split Between LPDDR5X and LPDDR6

Notably, Samsung’s LPDDR6 milestone comes as surging memory costs complicate the upgrade calculus for smartphone makers, forcing them to weigh next-generation performance against sticking with the more established LPDDR5X.

SamMobile, citing The Bell, reports that Samsung Electronics’ MX division is qualifying Micron’s latest 1γ (1-gamma) LPDDR5X for the Galaxy S27, suggesting at least some models could remain on the current generation product, though it remains unclear whether Samsung will source the memory from Micron or its own chip division.

Higher-end Galaxy S27 Pro and Ultra, however, could make the leap to LPDDR6, potentially paired with Qualcomm’s Snapdragon 8 Elite Extreme Gen 6, the report adds.

The Bell explains that Micron’s 1γ broadly aligns with the 1c DRAM generation at Samsung Electronics and SK hynix, succeeding its 1α and 1β nodes, which correspond to 1a and 1b, respectively. Micron is already in Samsung’s flagship supply chain, with its 1β LPDDR5X powering the Galaxy S26 alongside Samsung’s in-house memory, the report suggests.
