Rosetta 2

Project Kalamata is a codename within Apple Inc. to eventually replace Intel processors in its Mac product line with its own processors.

History
Apple had previously announced that it would switch from PowerPC processors to Intel processors in 2005 when IBM's development of the PowerPC G5 could no longer keep up with its product road map.

In April 2008, Apple acquired P.A. Semi for $278 million to bring fabless processor design in-house to the company, and to reduce dependence on Samsung for central processing units in its mobile products.

Apple initiated Project Kalamata in 2018 and is believed to have processors based on a 5nm version of the Apple A14 ready to replace Intel as soon as 2021, starting with entry level Macs.
