Release year20242024
Display6.3-inch Super Retina XDR OLED; 2622 × 1206, 460 ppi; ProMotion adaptive refresh up to 120 Hz

ProMotion changes the refresh rate with the content: 120 Hz smoothness when scrolling and gaming, lower rates on still images to save power. Apple quotes 1000 nits typical, 1600 nits HDR peak, 2000 nits outdoor peak and 1 nit minimum; peaks are not sustained full-screen brightness.

Apple		6.2-inch (6.0-inch with rounded corners) Dynamic AMOLED 2X; 2340 × 1080 (FHD+); adaptive 1–120 Hz; Vision Booster

The adaptive refresh rate drops to 1 Hz on static content to save power; Vision Booster adjusts tone and contrast in bright light.

ChipA18 Pro; 6-core CPU (2 performance, 4 efficiency); 6-core GPU; 16-core Neural Engine

Apple says A18 Pro, built on second-generation 3 nm technology, runs the same workload 15% faster with 20% less power than the previous generation; the GPU is up to 20% faster and hardware ray tracing up to 2× faster. The chip also enables faster USB 3 transfers and ProRes recording.

Rear cameras48 MP Fusion (24 mm, ƒ/1.78, second-generation sensor-shift OIS); 48 MP Ultra Wide (13 mm, ƒ/2.2); 12 MP 5× Telephoto (120 mm, ƒ/2.8, tetraprism); 2× Telephoto option (48 mm, using the Fusion sensor)

The Pro system covers a 10× optical zoom range from 0.5× to 5×, with digital zoom up to 25×. The 2× image is a 12 MP crop from the centre of the 48 MP main sensor, not a separate camera.

Apple		50 MP wide (ƒ/1.8, OIS, 85°); 10 MP 3x telephoto (ƒ/2.4, 36°); 12 MP ultra-wide (ƒ/2.2, 120°)

3x optical zoom uses the separate telephoto lens; the 2x option crops the main sensor at optical quality, and digital zoom reaches 30x.

Samsung
Video4K Dolby Vision up to 120 fps; Log recording and ACES; ProRes up to 4K 120 fps with external recording

4K at 120 fps allows high-frame-rate 4K footage that can be slowed down. Log recording produces a flat image that leaves more room for colour grading. High-bit-rate ProRes needs an external drive.

Apple		8K (7680 × 4320) at 30 fps; slow motion at UHD 120 fps and FHD 240 fps Samsung
Front camera and controls12 MP TrueDepth (ƒ/1.9, autofocus); Face ID; Camera Control; Action button

Apple says Camera Control combines a tactile switch, a force sensor and a capacitive surface: a click opens the camera, while a light press and finger slide adjust zoom, exposure or depth of field.
