Apple’s A20 chip, which doubtless 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 can 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 useless.
Extra particulars on the Apple A20 chip
As smartphones develop extra succesful, Apple’s push for chips which can be each highly effective and energy-efficient is essential. The upcoming A20 chip ought to enable Apple to provide iPhones with sooner 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 cell computing.
Apple’s A20 chip is predicted to come back 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 certain gained’t arrive till spring 2027.
As a fast refresher (as a result of the completely 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 technology, 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 response to Jeff Pu, analyst at GF Securities, the A20 will use TSMC’s new wafer-level multi-chip module (WMCM) know-how. This enables for a number of completely different dies and elements 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. At the moment, 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.
Apple’s first transfer to 2 nanometers

The A20 chip will likely 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, in line with earlier reviews, would possibly run 15% sooner with 30% larger energy effectivity.
If the sample of the previous few years holds regular, the M6 technology of bigger, extra highly effective chips may also 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 is perhaps introduced in late 2026 and all through 2027.
