Galaxy S26 Ultra to Feature 10.7Gbps LPDDR5X RAM — Micron’s 1γ Tech Promises Faster, More Efficient Performance

Overview: S26 Ultra's RAM Upgrade Explained

Samsung's next flagship, the Galaxy S26 Ultra, is shaping up to be a meaningful step forward in memory performance. Leaks indicate the phone will adopt LPDDR5X RAM capable of up to 10.7 gigabits per second (Gbps), a jump over the Galaxy S25 Ultra's 9.6Gbps modules. The faster memory — reportedly Micron's 1γ (1-gamma) LPDDR5X — targets demanding workloads including on-device AI and data-heavy applications.

Key Product Features

Faster LPDDR5X memory

The S26 Ultra is expected to ship with LPDDR5X DRAM running at 10.7Gbps, improving bandwidth for multitasking, gaming, and AI inference. Higher memory throughput reduces bottlenecks, enabling the chipset and neural engines to deliver results faster.

Improved power efficiency

Micron’s 1γ process claims up to 20% lower power consumption versus 1β LPDDR5X. That translates to slower battery drain during intensive tasks, longer screen-on time, and reduced thermal stress under load.

Reduced package size

At roughly 0.61mm, the newer DRAM package is more compact. The space savings could be reused for a larger camera sensor, bigger battery, or to slim down the phone’s profile.

Comparison: Galaxy S26 Ultra vs. S25 Ultra

While the Galaxy S25 Ultra used LPDDR5X modules built on Micron’s 1β process (and many models incorporated Micron parts due to supply shifts), the S26 Ultra’s shift to 1γ or Samsung’s equivalent 10.7Gbps modules would offer meaningful uplift:

• Bandwidth: 10.7Gbps vs 9.6Gbps — better throughput for apps and multitasking.
• Efficiency: up to 20% less power draw in 1γ memory.
• Thermals and reliability: newer process aims to address past overheating concerns.
• Space: thinner DRAM package encourages component rearrangement for enhanced features.

Advantages and Real-World Use Cases

For users, the upgrade means faster app load times, smoother multi-app workflows, and improved responsiveness in AI-driven features like on-device image processing and voice recognition. Mobile gamers and content creators will see benefits from higher memory bandwidth during graphics rendering and large-file editing. Enterprise and power users running data-intensive apps will also notice reduced latency and improved throughput.

Market Relevance and Supplier Notes

Reports point to Micron as the supplier of 1γ LPDDR5X, but Samsung's own 10.7Gbps DRAM (announced previously) could also be used. Last year’s LPDDR5X process issues prompted a mixed supplier strategy for the S25 lineup; testing and cross-sourcing appear to continue for the S26 series. Regardless of the vendor, consumers can expect similar performance and efficiency gains.

Conclusion

The Galaxy S26 Ultra looks set to combine a new-generation chipset with significantly faster, more power-efficient LPDDR5X memory. That combination will enhance AI workloads, extend battery life, and free internal space for other hardware improvements — all factors that could help Samsung strengthen its flagship position in a competitive smartphone market.
