PC Processors

[andurilski]

So my PC isn't Windows 11 compatible, no TPM. My question is, is a CPU upgrade sufficient or would I need a new motherboard to support TPM?

If a CPU upgrade would be sufficient, what CPU would you recommend (current performance is adequate for my needs running on Win 10)?

Thanks.

Current system: ASUS TUF B450-M PLUS GAMING, Ryzen 5 2400G, GTX 1650 SUPER, 16GB RAM (2400MHz - 2 x 😎

To get Win 11 approved you will need a Zen+ or newer AMD Processor. Zen+ are all 2000, 3000 Non-APU processors.

The 3000 or newer AMD processors you can enable  fTPM in BIOS to satisfy Win 11 requirement for TPM without installing a TPM separate card.

I have a Asus Motherboard with a 3700X with fTPM enabled in BIOS with Windows 11 Pro installed without any issues.

NOTE: According to your Asus Motherboard it supports AMD processors 3000, 4000, & 5000 series. All Zen+ or newer processors: https://www.asus.com/us/motherboards-components/motherboards/tuf-gaming/tuf-b450m-plus-gaming/helpde...

I would try to upgrade to the 5000 series CPU if you have the Budget. Don't forget to check your Motherboard's QVL list for RAM MEMORY for the new CPU you install to make sure it is compatible with the new processor also to upgrade to the correct BIOS Version or newer shown in your Motherboard's CPU LIST before installing the new CPU otherwise it won't boot up.

Wait my friend. Zen+ is actually the 2xxx series but the 2400G is not supported as its a first gen. (non plus)

Fun fact and confusingly enough (AMD naming style). The 1600F is Zen+ and supports Windows 11.

    If AMD wants, I'm free to name your next CPU. Just saying.

Stand corrected for the 2000 series CPU.  Thanks for the correction.  (Edited my first comment to reflex the 2000 series CPUs as being ZEN+ processors).

Seems like I had gotten the impression that most 2000 series CPUs were ZEN architecture and not ZEN+ in the past. But I always did mention that only ZEN+ CPUs were compatible with Windows 11 though. At least I got that part correct (- :  .

All ZEN+ 2000 series AMD Processor in the Compatibility List for Windows 11:https://www.pcworld.com/article/394793/what-cpus-can-run-windows-11.html  

(Article from 2021):

The AMD 1600AF is actually a Ryzen 2600 CPU rebranded which is why it is designated as a Zen+ processor.

Windows 11 doesn't support any ZEN AMD processors.

Latest Windows 11 Compatibility shows that the AMD 9000 series CPU are still not listed as being supported:https://windowsforum.com/threads/windows-11-24h2-update-expanded-amd-processor-support-revealed.3524...  (Article from February 2025):

What’s New?​

The latest official list now includes an array of AMD Ryzen processors that are cleared for running Windows 11 24H2. Here’s a snapshot of the supported models:

• Consumer and Professional Lineup:
• AMD Ryzen™ 7 8700G Processor
• AMD Ryzen™ 5 8500G Processor
• AMD Ryzen™ 5 8500GE
• AMD Ryzen™ 5 8600G Processor
• AMD Ryzen™ 3 8300G Processor
• Pro Series Additions:
• AMD Ryzen™ 5 PRO 8540U
• AMD Ryzen™ 7 PRO 8700G / 8600G
• AMD Ryzen™ 5 PRO 8600GE
• AMD Ryzen™ 5 PRO 8500G
• AMD Ryzen™ 3 PRO 8300G and 8300GE Processors
• AMD Ryzen™ 5 PRO 8640HS and 8640U
• AMD Ryzen™ 7 PRO 8840H, 8840U, 8845HS, and even the 8945HS

This comprehensive list is a clear indicator that Microsoft is committed to extending Windows 11’s reach. However, the update isn’t without its quirks.

Notable Absences​

Despite the expanded list, some expected models are conspicuously missing:

• High-End Performers: AMD Ryzen 9000 series and Ryzen AI Max+ processors are not yet part of the compatibility matrix.
• Legacy Components: Some of the components from the AMD 300 series have also not made the cut.

Why might these gaps exist? It could be a result of certification bottlenecks, driver optimization challenges, or perhaps Microsoft’s strategic decision to roll out compatibility in stages. Whatever the reason, users with these processors should keep an eye out for future updates.

"However, the absence of certain high-end models like the Ryzen 9000 and Ryzen AI Max+ processors serves as a gentle reminder that technology evolution is an ongoing process."

Thanks people. So basically a 5 3600, 5 4500, 5 5600 etc ok with bios enabling fTPM. I’ll have a hint for a processor at the price I fancy paying!
