We already knew that Apple could not use TSMC’s 3 nanometers for its Apple A16 chip, the Taiwanese foundryman having fallen too far behind in the development of this new fine engraving. It was thought that Apple could fall back on an intermediate etching of 4 nanometers, but the sources of ShrimpApplePro (@VNchocoTaco) indicate that the Apple A16 chip would ultimately remain engraved at 5 nanometers, like the two previous generations of chips.
There would still be progress independent of Apple’s design choices with an improved N5P engraving technique. For its part, Apple would also ” slightly “ improved the CPU, the GPU would also evolve and the great novelty of the year would concern the RAM with the adoption of the LPDDR5 standard, which shows speeds up 50% and power consumption up to 30% lower than the LPDDR4X of the Apple A15 chip.
The evolution of this year should therefore be quite modest, and it is a priori the Apple A17 chip which will go directly to 3 nanometers next year with the key to a 25% to 30% drop in consumption or an increase 10% to 15% performance over 5 nanometer engraving, all on a 42% smaller chip.
The Apple A16 chip could be disappointing in another way: Ming-Chi Kuo warned in March that this chip could be reserved for the iPhone 14 Pro and iPhone 14 Pro Max, while the iPhone 14 and iPhone 14 Max would be satisfied with the current Apple A15 chip (but with 6 GB of RAM instead of 4 GB on the iPhone 13).
