While not the first ({{\\|Lakefield}} was), Alder Lake is the first to target all market segments from mobile to desktop and workstation.

Succession

Alder Lake (ADL) is Intel's successor to both Tiger Lake and Rocket Lake, an Intel 7-process based microarchitecture for mainstream workstations, desktops, and mobile devices. Alder Lake is Intel's first 10-nanometer-class proper successor to all prior generation of processors - spanning from ultra-low power to desktop and workstations. The microarchitecture was developed by Intel's R&D center in Haifa, Israel.

For desktop and mobile, Alder Lake is branded as 12th Generation Intel Core i3, Core i5, Core i7, and Core i9 processors.

While not the first (Lakefield was), Alder Lake is the first to target all market segments from mobile to desktop and workstation. The overall microarchitecture builds on its predecessor, Tigerlake but expends on its by integrating two vastly different types of cores - up to eight big cores based on the Golden Cove microarchitecture and up to eight small cores based on the Gracemont microarchitecture.
