If accurate, the Galaxy S26 Ultra will ship with cutting-edge LPDDR5X RAM that not only runs faster but also consumes less power than the memory in its predecessor.The claim comes from tipster Ice Universe on X, who says the S26 Ultra will use LPDDR5X at 10.7 Gbps. That figure matches the top speed of chip-maker Micron’s 1γ (1-gamma) LPDDR5X, announced in June, which also promises up to 20% better power efficiency than the company’s last generation. The specific top speed and timing make it likely this is the chip behind the leak.
