Zen 3
Seems like a simple inquiry (sorry), but what exactly is Zen 3?
The design name for Ryzen 5000 series chips. First generation (Ryzen 1000): Zen Second generation (Ryzen 2000): Zen + Third generation (Ryzen 3000): Zen 2 Fifth generation (Ryzen 5000): Zen 3 Although AMD no longer officially uses "generation" after the second one, meaning the Ryzen 5 5600X isn't called "fifth gen"—it's just part of the 5000 series. APUs typically adopt the architecture from the last generation. The Ryzen 3 2200G is a second-gen model but uses Zen instead of Zen +, while the Ryzen 3 2300X employs Zen +. Missing "fourth generation" chips are all APUs (like the Ryzen 7 4700G) and they stick to Zen 2, plus they're OEM-only so they never reached regular stores.
Zen 3 refers to an AMD CPU design, widely used in modern desktops and mobile devices as well as some server and workstation models. Many of today's high-performance CPUs, such as the Ryzen 5000 series, are built on this platform. More details can be found at the official AMD site: https://www.amd.com/en/technologies/zen-core-3. A timeline of Zen 3 CPUs is available here: https://en.wikipedia.org/wiki/Zen_3#Desktop_CPUs. Prior architectures include Zen 2, Zen+, and earlier versions.
The motherboard claims support for 3rd generation CPUs, but your BIOS supports Zen 3. This means you likely don’t need a flash—just ensure your CPU is correctly recognized.
Your motherboard displaying "Ryzen 3000 ready" indicates it supports the 3700X, as both are from the same series. You can also check compatibility through simple methods. All B350 and X370 boards work with the first generation. B450 and X470 models fit the second generation. Third-gen boards include B550 and X570. Certain exceptions exist, such as the MSI MAX series for B450 boards built for 3000 series chips—those are also confirmed compatible. If your board lacks the "Ryzen 5000 ready" label, you may need to flash the BIOS for devices like the 5800X, though this is just an illustration. The BIOS version depends on the manufacturing date; for instance, many B550 and A520 boards show "Ryzen 5000 ready" since they launched before the 5000 series was introduced.
