Galaxy Tab S12 Ultra vs M5 iPad Pro: Screen Size, Brightness Parity and the Real Cost Gap

Samsung's Galaxy Tab S12 Ultra starts at $1,399.99 in a single 14.6-inch configuration, set directly against Apple's 13-inch M5 iPad Pro at $1,499 before accessories.

The head-to-head comes from an original comparison titled Samsung Galaxy Tab S12 Ultra vs Apple iPad Pro: Here's how they stack up, authored by Sam Rutherford and Nathan Ingraham and published Oct. 2 by Engadget. The piece focuses on Apple's largest option as the relevant foil for Samsung's Ultra, rather than the smaller 11-inch iPad Pro.

Pricing is where the segmentation gets explicit. Samsung offers only the 14.6-inch Ultra at the top, with the Galaxy Tab S12+ sitting below it as a 12.6-inch model starting at $1,199.99. Apple splits its line the other way, with an 11-inch iPad Pro listed at $1,199 in the comparison and a 13-inch version at $1,499 not including accessories. Apple's own newsroom material for the M5 iPad Pro breaks out the 11-inch line further, at $999 for Wi-Fi and $1,199 for Wi-Fi + Cellular. In practice the entry math overlaps. A buyer choosing between Samsung's smaller Plus and Apple's smaller Pro is looking at the same $1,199 starting point on paper, before cellular, storage, and pen or keyboard costs change the total.

Display specifications show two different approaches converging on similar brightness targets. The Galaxy Tab S12 Ultra uses a 14.6-inch Dynamic AMOLED 2X panel at 2,960 x 1,848 with a 120Hz adaptive refresh rate. Samsung rates it at 1,000 nits in High Brightness Mode and 1,600 nits peak brightness. Apple uses an Ultra Retina XDR display, offered in 11-inch and 13-inch sizes, rated at 1,000 nits full-screen and 1,600 nits peak for HDR content.

Size is the more material difference for day-to-day use. Samsung is committing the Ultra to 14.6 inches with no smaller variant. Apple caps the comparison at 13 inches. That 1.6-inch diagonal gap matters for split-screen multitasking, stage-managed windows, drawing canvas, and video timelines. It also matters for weight, bag fit, and one-handed handling. The 13-inch M5 iPad Pro measures 11.09 by 8.48 by 0.20 inches and weighs 1.28 pounds, according to PCMag. Samsung has not countered in this data set with equivalent published dimensions for the Ultra in the comparison, framing the S12 series instead around an ultra-thin design with long-lasting battery life and integrated Galaxy AI.

On silicon, Samsung claims a 19 percent increase in CPU performance and a 17 percent increase in GPU power for the Galaxy Tab S12 Ultra, figures reported in Engadget's separate S11 Ultra versus S12 Ultra breakdown. Those are vendor-provided generational deltas, not cross-platform benchmarks against M5, and they should be read that way. Apple introduced the M5 iPad Pro in October 2025, according to Apple. The current comparison does not provide shared test results between the two shipping tablets, which leaves sustained performance, thermal behavior, and inference throughput for on-device AI workloads unresolved in the verified facts.

Samsung Electronics unveiled the Galaxy Tab S12 series as two models, the Galaxy Tab S12 Ultra and Tab S12+. The company describes the line as its most capable and versatile tablet experience yet, and announced it under the productivity positioning for growth and mobile work. The Galaxy AI integration is presented as part of that package, inside the thin chassis and long-life battery envelope. Both the Tab S12 Ultra and Tab S12+ ship with an included S Pen, according to Samsung's product pages. Samsung also lists a Galaxy Tab S12 Ultra 5G configuration in Gray with 256GB storage.

Accessory bundling is a quiet but real part of the value calculation. An included pen removes a separate purchase decision for note-taking, markup, and sketching workflows. Apple's 13-inch price is stated without accessories, which means keyboard and pencil costs sit outside the $1,499 baseline. Storage and cellular uplifts will move both stacks quickly past their entry prices. Professionals who live in PDF review, CAD markups, or classroom annotation will feel that difference immediately. Others who type far more than they draw may weight keyboard pricing more heavily.

Coverage is already clustering around this pairing. Trusted Reviews published Samsung Galaxy Tab S12 Ultra vs iPad Pro M5, and PCMag published a Samsung Galaxy Tab S12 Ultra Review in the same Sept. 30 window as Samsung's announcement cycle. The throughline is consistent. These are no longer companion devices. They are primary computers for a subset of users, evaluated on window management, external display support, file handling, and accessory ecosystems as much as on panel quality.

The broader context here is that brightness and refresh parity makes the choice less about spec-sheet peaks and more about platform constraints. In this author's view, the relevant questions are mundane and decisive. Which OS handles your existing documents, identity management, and peripherals with less friction. Whether 14.6 inches helps your particular multitasking layout enough to accept the larger footprint. Whether included pen input versus a separately priced input stack changes your actual usage, since tools left in a drawer do not improve productivity.

Worth flagging for enterprise buyers is how cleanly the two lines map to different defaults. Samsung is leaning on screen area, AMOLED supply-chain strength, and pen-in-box to argue for field work, review workflows, and media consumption on one device. Apple is leaning on silicon consistency across Mac and iPad, a mature tablet app catalog, and a 13-inch ceiling that preserves a degree of portability. Neither approach eliminates trade-offs. Larger glass improves side-by-side editing and presentation. Smaller glass travels better and docks more easily into tight desk setups.

What this enables, over the longer arc, is encouraging. High-brightness, high-refresh large tablets with capable CPUs and GPUs, hardware-accelerated AI features, and credible pen input are now baseline expectations rather than outliers. My kids grew up tapping glass that was strictly for consumption. Their equivalents now edit video, sign forms, attend class, and run work apps on the same slab. The S12 Ultra versus M5 iPad Pro debate reflects that shift. The hardware is good enough on both sides that workflow fit, not peak nits, will decide.
