Galaxy S26 Ultra’s big ace over predecessor revealed

The Galaxy S25 Ultra, like most top Android phones powered by the Qualcomm Snapdragon Elite Mobile Platform, comes with LPDDR5X built on Micron’s previous-gen 1β (1-beta) process technology and delivers speeds up to 9.6 Gbps.

In contrast, the Galaxy S26 Ultra‘s RAM will be based on Micron’s 1γ (1-gamma) DRAM technology.

Micron claims that its 1γ LPDDR5X​​ offers the industry’s fastest RAM speed — 10.7 ​ ​Gbps — which makes it ideal for AI use cases and data-intensive apps. Users can expect faster response and result delivery times.

1γ LPDDR5X​​ also enables up to 20 percent power savings compared to 1-beta ​LPDDR5X​​​ memory​​. This means that the Galaxy S26 Ultra will burn through its charge at a slower rate than the Galaxy S25 Ultra.The new component will also take up less space, coming in at just 0.61mm​, potentially freeing up room for other components such as a larger camera sensor or a bigger battery.

The Galaxy S26 Ultra is also expected to feature an upgraded design and a thinner profile. The Galaxy S25 is doing quite well and an improved Galaxy S26 Ultra with speedier performance will help the company build on that success.
