Samsung’s upcoming flagship, the Galaxy S26 Ultra, could be one of the fastest smartphones the company has ever made. According to fresh leaks, the device may be powered by Samsung’s new 10.7Gbps LPDDR5X RAM, a cutting-edge memory technology designed to deliver both speed and efficiency upgrades.
The LPDDR5X RAM was first announced by Samsung’s semiconductor division in April 2024. Built using a 12nm process, it is the smallest LPDDR chip Samsung has produced so far. More importantly, it promises more than a 25 percent improvement in performance, over 30 percent higher capacity, and 25 percent better power efficiency compared to its predecessor. This means smoother multitasking, faster app loading times, and better battery life, all without increasing the device’s size.
Reports suggest the Galaxy S26 Ultra will launch alongside the Galaxy S26 Pro and Galaxy S26 Edge. While some conflicting information exists about whether this RAM was already used in the Galaxy S25 Ultra, the production timeline for the new memory indicates it is more likely making its debut in the S26 Ultra. Given the increased performance demands of modern smartphones especially with AI-driven features and high-resolution displays this upgrade could give Samsung’s flagship a noticeable edge in day-to-day use.
If these leaks turn out to be accurate, the Galaxy S26 Ultra will not only bring the latest Snapdragon 8 Elite Gen 2 processor but also one of the fastest and most efficient RAM technologies currently available in the smartphone market. Combined, these upgrades could make it one of the most powerful Android devices of 2025.
