AMD Ryzen 7000-era CPU architecture. Desktop parts use socket AM5 and DDR5 memory.

What you need to know

Zen 4 is the Ryzen 7000 desktop architecture.

Desktop Zen 4 chips sit on AM5 and use DDR5. They are not drop-in parts for AM4 boards. Later Zen 5 parts stayed on AM5 with a BIOS check.

Socket?
AM5 on desktop
DDR4?
Desktop AM5 is DDR5
Still current?
Later Zen generations exist. Zen 4 is still capable
Feex says
If you are coming from AM4, you are buying a board and memory too. The chip name is not the whole bill.

What Zen 4 is

Zen 4 is AMD's CPU architecture used in Ryzen 7000 desktop parts and related mobile SKUs. Desktop Raphael chips use socket AM5.

What it means on a PC

You need an AM5 board and DDR5. The chip can include graphics on non-F parts. Gaming still follows the GPU more often than the architecture name.

Upgrade notes

AM4 to AM5 is a platform change. AM5 to a later Zen chip on the same board is a BIOS and list check.

  • New board and DDR5 from AM4
  • BIOS update for later AM5 chips
  • Check the cooler AM5 kit
