An official Intel 12th Gen Alder Lake CPU slide has been leaked by Videocardz which confirms the next-gen desktop & mobility lineup offering up to 20% single-threaded performance increase. The Intel 12th Gen Alder Lake CPUs are expected to launch in the second half of 2021, replacing Intel's 11th Gen Rocket Lake Desktop and Tiger Lake Mobility chips.

In its official slide, Intel calls the Alder Lake a 'Breakthrough CPU Architecture. The company claims that its 12th Gen processors will offer a 20% single-threaded performance uplift and a 2X uplift in multi-threaded tasks. The Intel Alder Lake CPUs will be the first CPUs fabricated on the brand new 10nm Enhanced SuperFin process node which is a refined and more optimized version of the 10nm SuperFin process node used to manufacture the current Tiger Lake CPUs.
