Galaxy Tab S12 Ultra vs Galaxy Tab S11 Ultra: What's New and Is It Worth It?

Based on pre-launch details available as of July 2026, the Galaxy Tab S12 Ultra is expected to arrive around September 22, 2026 with two headline changes: a switch to the MediaTek Dimensity 9500 processor and a refined 14.6-inch AMOLED display panel. Samsung has not confirmed final specifications, and details are subject to change before the official Unpacked announcement.

What appears unchanged based on current reports: the large 14.6-inch form factor, the built-in S Pen slot, and the thin-bezel design that made the S11 Ultra a productivity-focused flagship. This article will be updated when Samsung announces the final spec sheet.

Both tablets use a 14.6-inch AMOLED panel. The Galaxy Tab S11 Ultra ships with Samsung's Dynamic AMOLED 2X technology, covering the DCI-P3 wide color gamut at up to 120Hz. The Tab S12 Ultra is expected to keep the same diagonal and refresh rate, with panel refinements that Samsung typically describes as improvements to peak brightness and color accuracy.

For the majority of S11 Ultra owners, the display is already excellent. Samsung's incremental display improvements across the Tab S line have been meaningful but rarely disruptive — the jump from one generation's peak brightness to the next is noticeable in direct sunlight but invisible in normal indoor use. The display is unlikely to be a deciding factor on its own.

The processor swap is the biggest unknown in this comparison. The Galaxy Tab S11 Ultra runs on Qualcomm's Snapdragon 8 Elite, which delivered a meaningful single-core performance gain when it launched. A shift to MediaTek's Dimensity 9500 would be a notable change in Samsung's flagship tablet supply chain.

MediaTek has closed the performance gap with Qualcomm significantly over the past two years, and the Dimensity 9500 is MediaTek's top 2025-2026 chip built on a 3nm process. For general productivity — spreadsheets, document editing, video calls, and casual creative work — the real-world difference between the two chips will likely be minimal. For AI-accelerated workloads and demanding games, the comparison will depend on final benchmark results at launch. See Samsung's official Galaxy Tab page for confirmed specs once announced.

The Galaxy Tab S11 Ultra ships with an 11,200 mAh battery and 45W wired charging. Pre-launch information for the S12 Ultra does not point to a dramatic battery capacity change, but Samsung typically improves real-world battery life through processor efficiency gains rather than raw capacity increases.

The built-in S Pen slot and included S Pen are expected to carry over to the S12 Ultra. The S Pen is one of the Galaxy Tab Ultra's most distinctive features and Samsung has kept it through every generation. For those who use it heavily for note-taking or sketching, continuity here matters more than chip specs.

On depreciation: flagship tablets commonly lose 30 to 50% of their resale value within the first 12 months after a successor launches (source: BuyBackBear price-history tracking and industry resale data). If you own an S11 Ultra and do not need the S12 Ultra's new chip, selling now and applying those proceeds to an S12 Ultra at launch is financially rational — you capture peak S11 Ultra value and start fresh. See our guide to selling your Galaxy Tab S11 Ultra for the full checklist.

The honest case for upgrading: if you use your tablet heavily for AI-accelerated workloads and the Dimensity 9500 proves faster in those specific tasks, or if Samsung delivers a display refinement that matters for your use case, the S12 Ultra is a reasonable step up. Early adopters and power users with processor-dependent workflows have the clearest reason to consider it.

The honest case against: the Galaxy Tab S11 Ultra with Snapdragon 8 Elite is a fast, capable tablet that will remain competitive well into 2027 for productivity, media consumption, and casual creative work. A chip upgrade alone does not meaningfully change what you can do day to day.

The most financially rational path if you do plan to upgrade: sell your S11 Ultra before Samsung's fall announcement when values are at their peak, then decide after the official launch whether the S12 Ultra's real-world improvements justify the price. Waiting to sell until after the announcement costs you money regardless of whether you end up buying the new model.

If you decide to sell, timing and preparation directly affect what you receive. The Galaxy Tab S12 Ultra announcement in September 2026 is the event that resets S11 Ultra values. Selling in July or August puts you ahead of that curve.

Before shipping your tablet: sign out of your Samsung account and Google account, run a factory reset, include the S Pen and charger if you have them, and photograph any cosmetic wear honestly. A tablet with an active Samsung account attached cannot be set up by the next owner and will be returned or devalued.
