One of the most talked-about leaks for the Samsung Galaxy S26 Ultra centers on its memory (RAM) configuration and performance. According to multiple credible leaks, Samsung is expected to equip the S26 Ultra with cutting-edge LPDDR5X memory running at up to ~10.7 Gbps, a notable jump over the ~9.6 Gbps LPDDR5X used in the Galaxy S25 Ultra. This faster memory is tipped to improve overall responsiveness, app loading, multitasking and data-intensive tasks, making performance smoother and more efficient.
Leakers such as Ice Universe (via social media tips) have stated that LPDDR5X @ 10.7 Gbps will likely be standard across the Galaxy S26 lineup, including the Ultra model, with 12 GB as the base RAM configuration and higher-end variants continuing to offer 16 GB in select markets (e.g., China).
Performance & Power Efficiency Benefits The higher memory speed is not just about raw bandwidth; leaks suggest it may also lead to better power efficiency and potentially improved thermal behaviour. Faster memory bandwidth can help reduce latency and improve performance in camera processing, gaming and AI-assisted tasks. Some analyses even claim the S26 Ultra’s upgraded memory might operate at a slightly lower voltage, which could reduce heat generation and maintain peak performance longer under load.
RAM & Storage Configurations Based on early leaks, the Galaxy S26 Ultra is expected to offer several RAM/storage combos. Globally, the phone is tipped to launch with 12 GB of RAM paired with 256 GB or 512 GB of storage; in certain markets like China, a 16 GB + 1 TB configuration might be offered as a premium option.
Broader Memory Strategy These memory upgrades fit within Samsung’s broader 2026 flagship strategy, where faster LPDDR5X is reportedly being adopted across the entire Galaxy S26 series, not just the Ultra. This would bring a notable speed bump over the previous generation and align with performance demands from heavy multitasking, productivity workflows, and advanced camera processing.
Other Related Hardware Leaks While not strictly memory related, other leaks indicate the Galaxy S26 Ultra will pair this faster RAM with top-tier flagship internals such as the Snapdragon 8 Elite Gen 5 chip (or regionally, Exynos 2600), a high-resolution screen and refined camera system which together help define the overall next-generation performance profile.
