Google testing LPDDR5X and LPDDR6 memory for upcoming Tensor G7 chip

Google is reportedly evaluating two types of high-speed memory—LPDDR5X and LPDDR6—for its upcoming Tensor G7 system-on-chip, according to a post on the X platform citing Reptalica. The company is said to be testing both memory standards, with the faster LPDDR6 possibly reserved for higher-end Pixel models.

Analysts note that LPDDR6 offers greater bandwidth and a wider 96-bit bus, which could reduce latency and improve communication between the CPU and RAM. If adopted, the upgrade might enhance on-device artificial-intelligence tasks that rely on large language models stored in memory, even if the core compute performance remains similar to the current Tensor G6.

The rumor also suggests that Google could change its packaging approach, moving from traditional package-on-package (PoP) to wafer-level multi-chip module (WMCM) designs to address thermal constraints associated with higher-speed memory. Past examples include Apple’s shift to WMCM after AI-related performance concerns.

While the dual-memory testing indicates a potential differentiation between standard and ‘Pro’ Pixel devices—mirroring Google’s earlier use of Zoned UFS storage for premium models—the report cautions that rising DRAM costs might lead the company to abandon LPDDR6 support altogether. The information remains unconfirmed and should be treated as speculative.
