Apple now able to design 5nm A-Series chips for 2020 iPhones as TSMC hits a key milestone:

It’s looking like Apple chipmaker TSMC is on track for being able to produce 5nm A-Series chips for 2020 iPhones.

We heard as long ago as the beginning of last year that Taiwan Semiconductor Manufacturing Company was gearing up for that target, and a new report today says that the firm has just hit a major milestone along the way …

DigiTimes reports that the design infrastructure is now complete, enabling clients like Apple to begin work on their chip designs using the 5nm process.
As well as a logic density 1.8 times greater than current generation chips, the 5nm process is expected to deliver significant gains in both speed and power efficiency.
TSMC has long been Apple’s sole supplier of A-series chips thanks to its quest for ever-smaller processes leaving Samsung behind. The company isn’t stopping at 5nm, reportedly aiming for 3nm production in 2022.

Samsung still has a monopoly on iPhone X-family displays but isn’t likely to retain that for long. Competitors like LG Display and Japan Display are pitching for Apple’s business, while TSMC is looking further ahead to microLED
