Here’s your cheat sheet for AMD’s Zen-based CPU nomenclature

You're probably familiar with terms like Ryzen and Zen, but the deeper you dive into AMD's modern processor architectures, codenames, and product releases, the more confusing it can be. Zen 2, for example, is actually the third generation of Zen, while a Ryzen 3000 series CPU can be either a second-gen or third-gen part. It can be a bit overwhelming for casual observers, and still difficult to navigate even if you follow tech more closely. Not to worry, though, I've put together a handy cheat sheet that you can reference as needed.

Let's start with Zen. That is the name of the underlying CPU architecture that AMD uses nowadays for the chips slotted into the best AMD motherboards, and has been since the introduction of its first-generation Ryzen processors, like the Ryzen 7 1700. There are now three generations of Zen, each built on a smaller manufacturing node than the last (which in turn has led to faster clockspeeds, improved power efficiency, and better performance). Here they are:

  • Zen (14 nanometers)
  • Zen+ (12 nanometers)
  • Zen 2 (7 nanometers)

If things go to plan, there will be Zen 3 CPUs next year, built on a refined version of 7nm (called 7nm+). That will be the fourth generation of Zen.

This only slightly confusing, because logically, it would seem that Zen 2 is a second-generation product, but that slot is filled by Zen+. Where things take a turn for the quirky is with the numbering series that AMD uses for its APUs (Ryzen processors with integrated graphics) and desktop processors. Here's how it breaks down on the desktop, along with the codenames:

  • 1st generation Ryzen (1000 series): Zen, 14nm—Summit Ridge
  • 2nd generation Ryzen (2000 series): Zen+, 12nm—Pinnacle Ridge
  • 3rd generation Ryzen (3000 series): Zen 2, 7nm—Matisse

From that, it's easy to tell that a Ryzen 7 1700 is a first-gen Ryzen processor based on 14nm Zen, whereas a Ryzen 7 2700X chip is a second-gen Ryzen CPU based on Zen+, and so on.

APUs are different though. There two generations of APUs:

  • 1st generation Ryzen APU (2000 series): Zen, 14nm—Raven Ridge
  • 2nd generation Ryzen APU (3000 series): Zen+, 12nm—Picasso

This is where the main confusion stems from, because the numbering scheme doesn't align with AMD's regular desktop Ryzen CPUs. For example, a Ryzen 5 2600H (APU) is based on first-gen Zen (14nm), but a Ryzen 5 2600 is a second-gen Zen+ (12nm) CPU. Also note that there are no second generation desktop APUs.

It's a bit much to keep track of, so to make things easier, I've listed every Ryzen CPU and APU, noting the architecture and codename. It's a long list, but here goes, starting with every first-gen Zen (14nm) processor (not including embedded offerings):
