Alder Lake is Intel's codename for the 12th generation of Intel Core processors based on a hybrid architecture utilizing Golden Cove big cores and Gracemont small cores.[1] Intel expects to launch Alder Lake in the second half of 2021. It is expected to use the 10nm SuperFin process and a new LGA 1700 socket[2] with DDR5 support.
