The A20 chip, which is able to energy the iPhone 18 Professional and folding iPhone, will use a brand new expertise that integrates RAM contained in the chip. Bringing the reminiscence nearer to the CPU, GPU and Neural Engine could have a major impact on efficiency, battery life and thermal effectivity.
It is going to even be Apple’s first chip on the cutting-edge 2 nanometer course of. Rumors that the die shrink would arrive this 12 months now appear to be completely useless.
Extra particulars on the Apple A20 chip
Apple’s A20 chip is predicted to come back within the iPhone 18 Professional, iPhone 18 Professional Max and the folding iPhone in September, 2026. The entry-level iPhone 18 and iPhone 18e could not obtain the A20 chip — and could not arrive till spring 2027.
As a fast refresher (as a result of the completely different numbers can get complicated) Apple at present sells the iPhone 16 with 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 subsequent fall.
Whereas Apple designs its personal silicon, all of its chips are manufactured by TSMC, the Taiwan Semiconductor Firm.

In keeping with Jeff Pu, analyst at GF Securities, the A20 will use TSMC’s new Wafer-Degree Multi-Chip Module (WMCM) expertise. This enables for a number of completely different dies and parts to be built-in right into a single package deal.
Apple will use the WMCM course of to combine the RAM contained in the chip, alongside the CPU, GPU and Neural Engine. Presently, 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, places extra transistors on the chip and improves efficiency.
The A20, in accordance with earlier reviews, could run 15% quicker with 30% larger 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 also be introduced in late 2026 and all through 2027.
