The rumor, circulated by a tipster and echoed by X leaker TheGalox_, claims the upcoming Galaxy S27 Ultra will be equipped with LPDDR6 memory, a first for Samsung’s flagship line, and that a second model – tentatively dubbed the Galaxy S27 Pro – could also receive the same memory configuration.
According to the same source, both devices might also adopt UFS 5.1 storage, a step up from the UFS 5.0 standard used in the current generation.
However, a promotional image released by Qualcomm for its Snapdragon 8 Elite Extreme Gen 6 processor – the chipset Samsung has been testing – explicitly lists support for UFS 5.0 rather than UFS 5.1, contradicting the leak’s storage claim.
Samsung has publicly confirmed that it has validated LPDDR6 memory on the Snapdragon 8 Elite Extreme Gen 6, but the validation was limited to a 16 GB configuration, suggesting that only one of the upcoming flagships may carry that amount of RAM.
The conflicting details have led analysts to caution that the rumor of both the Ultra and a Pro model receiving LPDDR6 remains unverified, and that a Snapdragon‑Exynos split across regions could further complicate the final hardware lineup.
If the LPDDR6 upgrade materialises, Samsung says the new DRAM could deliver up to 21 % better power efficiency than LPDDR5X and provide a memory bandwidth of up to 114 GB/s, benefits that would accelerate on‑device AI processing and other intensive tasks.
Market observers note that such hardware improvements could justify a price increase of $50 to $200 over the current S26 Ultra, depending on how extensive the upgrades are and whether they are limited to a single 16 GB variant.
Until Samsung releases official specifications, the exact memory and storage configuration of the Galaxy S27 series remains speculative, with the industry watching for further confirmation on the chipset and RAM rollout.
