One of the flagship features of the iPhone 12 and iPhone 12 Pro is support for 5G connectivity. There is support for mmWave 5G in the United States exclusively, and support for sub-6GHz 5G in other countries as well as in the U.S. The iPhone 12 and iPhone 12 Pro are also both powered by a new A14 Bionic processor that uses a new 5-nanometer process to reduce transistor size. Apple says the new six-core CPU is up to 50% faster than any other smartphone. The iPhone 12 also includes a new 4-core GPU, which is up to 50% faster than the competition.
