Apple’s A20 chip, which seemingly will energy the iPhone 18 Professional and folding iPhone, reportedly will use a brand new know-how that integrates RAM contained in the chip. Bringing the reminiscence nearer to the CPU, GPU and Neural Engine would possibly present important boosts in efficiency, battery life and thermal effectivity.
The A20 additionally could be Apple’s first chip produced utilizing the cutting-edge 2 nanometer course of. Rumors that the die shrink would arrive this 12 months now appear to be completely lifeless.
Extra particulars on the Apple A20 chip
As smartphones develop extra succesful, Apple’s push for chips which might be each highly effective and energy-efficient is essential. The upcoming A20 chip ought to enable Apple to supply iPhones with quicker processing speeds and higher battery life, whereas packaged into more and more slim designs. In a world the place each milliwatt counts, Apple’s silicon ambitions are about excess of uncooked energy. They’re about sustaining the way forward for cellular computing.
Apple’s A20 chip is anticipated to return within the iPhone 18 Professional, iPhone 18 Professional Max and the primary folding iPhone in September 2026. The entry-level iPhone 18 and iPhone 18e may not obtain the A20 chip — and seemingly received’t arrive till spring 2027.
As a fast refresher (as a result of the totally different numbers can get complicated), Apple at the moment sells the iPhone 16, which runs on an improved 3nm A18 chip. This fall, Apple will debut the iPhone 17 with a third-generation 3nm A19 chip. This newest rumor pertains to the iPhone 18 era, coming in fall 2026.
Whereas Apple designs its personal silicon, all of its chips are manufactured by the Taiwan Semiconductor Firm, aka TSMC.
The RAM is coming from inside the home

In line with Jeff Pu, analyst at GF Securities, the A20 will use TSMC’s new wafer-level multi-chip module (WMCM) know-how. This permits for a number of totally different dies and elements to be built-in right into a single bundle.
Apple will use the WMCM course of to combine the RAM contained in the chip, alongside the CPU, GPU and Neural Engine. At present, the RAM is a separate chip subsequent to the A18.
This might additional enhance reminiscence efficiency, thermal effectivity and battery life on the iPhone 18 lineup.

The A20 chip will probably be Apple’s first to make use of TSMC’s 2nm course of. Extra superior processes, with smaller and smaller die sizes, put extra transistors on the chip and enhance efficiency.
The A20, based on earlier studies, would possibly run 15% quicker with 30% higher energy effectivity.
If the sample of the previous few years holds regular, the M6 era of bigger, extra highly effective chips can even fabricated on the 2nm course of. The M-series chips are utilized in Macs, mid- to high-end iPads and the Imaginative and prescient Professional headset. These merchandise could be introduced in late 2026 and all through 2027.
