Succession
Tiger Lake Rocket Lake Raptor Lake

Alder Lake (ADL) is Intel's successor to Tiger Lake, a 10 nm microarchitecture for mainstream workstations, desktops, and mobile devices.

Codenames

Core	Abbrev	Platform	Target
Alder Lake M	ADL-M		Light notebooks, 2-in-1s detachable, tablets, conference room, computer sticks, etc.
Alder Lake P	ADL-P		Ultimate mobile performance, mobile workstations, portable All-in-Ones (AiOs), Minis
Alder Lake S	ADL-S		Desktop performance to value, AiOs, and minis

Process Technology

Intel is planning Alder Lake to be built on an improved Intel 7 node (previously 10nm Enhanced SuperFin (ESF)). This will be the case for both the powerful Golden Cove cores, and Gracemont cores.

History

In January 2021 Intel teased Alder Lake in their CES 2021 speech. On the July 26th's Intel Accelerated webcast, CEO Pat Gelsinger hinted at the Alder Lake lineup being released at a future event called "Intel Innovation" which aired between October 27-28th.

Architecture

Key changes from Tiger Lake

• Core
  • Hybrid Golden Cove (big core) & Gracemont (small core) microarchitecture
  • At least 20% IPC improvements
  • Intel 7 node
• Memory
  • Support for DDR5
  • Speeds of at least 4800MHz, up to 5600MHz
• Improved power delivery system

Die

Alder Lake comes in four die variants depending on the market segment.

Die
Name	Configuration	Dimensions	Area
ADL-S	8P + 8E	10.5 mm x 20.5 mm	215.25 mm²
	6P + 8E	10.5 mm x 15.5 mm	162.75 mm²
ADL-P	6P + 8E
ADL-M	2P + 8E

ADL-S (8P+8E)

• 8 performance cores + 8 efficiency cores
• Intel 7 process
• 10.5 mm x 20.5 mm
  • 215.25 mm² die size

ADL-S (6P+0E)

• 6 performance cores + 8 efficiency cores
• Intel 7 process
• 10.5 mm x 15.5 mm
  • 162.75 mm² die size
