# Alder Lake

Architecture: Intel

Also called alder lake, 12th gen, alder lake-s

Intel, Architecture

Intel 12th-generation Core architecture. Desktop parts use LGA1700 and mix performance cores with efficiency cores.

## What you need to know

Alder Lake is the 12th-gen hybrid Core line.

Desktop Alder Lake chips sit on LGA1700 and mix performance cores with efficiency cores. The i7-12700KF is a common example. Later 13th and 14th-gen parts stayed on the same socket.

- **Still relevant?**: Yes, for many desktops

  **Socket?**: LGA1700 on desktop

  **What is new here?**: P-cores plus E-cores

Feex says

If your board is LGA1700, the architecture name matters less than the BIOS revision. A shared socket is not a free upgrade.

## What Alder Lake is

Alder Lake is Intel's 12th-generation Core architecture. Desktop SKUs introduced a hybrid mix of performance cores (P-cores) and efficiency cores (E-cores) on the LGA1700 socket.

## What it means on a PC

Windows schedules work across both core types. Everyday apps often land on E-cores. Games and heavy threads prefer P-cores. Task Manager can show both. That split is expected, not a broken CPU.

## Upgrade notes

A later LGA1700 chip can fit the same board only if the vendor BIOS list includes it. Read the motherboard CPU list. Do not assume a 14th-gen part posts on an untouched 2021 BIOS.

- Confirm the board list
- Update BIOS before you swap
- KF SKUs still need a discrete GPU
