Apple To Move Directly To 3NM -- Nothing About The Bakken -- Unless This Is A Story About The iPhones That The Spouses Of Roughnecks Prefer -- May 28, 2022

For background, see the blog at this link.

From MacRumors today: Apple chips plans suggest "A16" will stick with 5nm, but the "M2" will make the jump to 3nm instead. 

The "A16" chip for the iPhone will reportedly be manufactured with the same process as the iPhone 13's A15 Bionic, with Apple saving a bigger performance leap for the "M2" chip designed for its next-generation Macs. Meanwhile, the company is working on a "final" M1 chip variant that uses more powerful cores from the A15, according to the leaker known as "ShrimpApplePro."

The A16 will reportedly be based on TSMC's 5nm process, just like the A14, A15, and M1 chips. Previous reports have been unclear about whether the A16 will be fabricated with TSMC's more advanced 4nm process, with an ambiguous report from DigiTimes claiming that Apple plans to use TSMC's 4nm N4P process – but N4P is in fact an enhanced, third-generation version of the 5nm process. On the other hand, ShrimpApplePro said that the A16 will use TSMC's N5P process. This suggests that the A16 may be less of a substantial upgrade than previously thought.

The M2 chip will apparently be the first Apple chip to make the jump to TSMC's 3nm process, skipping 4nm entirely. The M2 is believed to be Apple's first custom ARMv9 processor.

Apple is also said to be working on the "final SoC of M1 series," featuring updated cores. The M1, M1 Pro, M1 Max, and M1 Ultra chips use energy-efficient "Icestorm" cores and high-performance "Firestorm" cores – just like the A14 Bionic chip. Apple's final M1 variant will instead allegedly be based on the A15 Bionic, featuring "Blizzard" energy-efficient cores and "Avalanche" high-performance cores.

INTC: no clue.
