Apple launched the A18 and A18 Professional proper in time for the iPhone 16 sequence, and the Professional was stated to have a extra highly effective GPU for intensive graphical duties like augmented actuality, 3D rendering and ray tracing.
Now photographs of the particular chips had been posted on-line, showcasing the platforms are fairly completely different regardless of being constructed by TSMC on the identical 3 nm course of know-how.

TSMC utilized the InFO-PoP (Built-in Fan-Out Bundle-on-Bundle) methodology, which stacks DRAM packages straight on high of the SoC die, incorporating high-density RDL (Redistribution Layers) together with TIV (By way of InFO Through). That manner, the general chip measurement is decreased, guaranteeing robust thermal and electrical efficiency.
A deeper look into the die shot reveals the A18 Professional does have extra transistors, which implies extra energy for the Professional, permitting for higher general efficiency.

Apple was stated to order all of the TSMC 2 nm course of know-how capabilities for the A19 chips. Nonetheless, analysts claimed Cupertino will solely launch the iPhone 17 Professional duo with 2 nm chips as a result of the Taiwanese maker is having points with yields.
