As expected, Apple today announced a new chip — though with a name few people expected: the M1 Pro, a more powerful version of the M1 chip, which made its debut last November and has since started to power a variety of Apple devices. Apple promises that the M1 Pro is up to 70% faster than the original M1.

In addition, it also launched the M1 Max, an even more powerful version of the Pro. You can read more about it here.
