Samsung quotes 40% NPU, 37% CPU and 30% GPU gains over the previous generation. This version is tuned for Galaxy with higher clocks than the standard Snapdragon 8 Elite.

The viewable area is smaller than the diagonal because of rounded corners and the camera hole. Refresh that drops to 1 Hz saves power on static content; Vision Booster adjusts tone mapping in bright light.

Protection may deteriorate with wear; pool or beach use is not advised.

Samsung notes memory options may vary by market and usable storage is lower because of preloaded software. There is no card slot.

The vapor chamber spreads heat from the chip into the body, helping clocks hold longer in extended gaming.

Titanium is used only on the frame, excluding the volume and side keys.
