Fedora x86-64-v3 Optimized Packages Pushed Back To At Least Fedora 46
A proposal to build x86-64-v3 packages for Fedora 45 has been delayed, but may be reconsidered for Fedora 46. The x86-64-v3 micro-architecture feature level is for Intel and AMD processors of roughly the past decade or longer.

x86-64-v3 Delayed, But May Be Reconsidered For Fedora 46
The proposal to build x86-64-v3 packages for Fedora 45 has been delayed, but may be reconsidered for Fedora 46. This would allow for better performance on newer hardware, including Intel and AMD processors of roughly the past decade or longer.
The x86-64-v3 micro-architecture feature level is for Intel and AMD processors of roughly the past decade or longer. Intel Haswell and newer or AMD Excavator CPUs and newer cover x86-64-v3 where there is AVX/AVX2, FMA, BMI(2), MOVBE, XSAVE, and other ISA capabilities. Some Linux distributions like RHEL 10 already require x86-64-v3 as a sane default since it basically covers nearly all Intel/AMD systems of the past decade.
There was a proposal to add x86-64-v3 as a primary architecture on Fedora Linux while retaining x86-64 (v1) support for those on dated systems. This is of interest to many parties for better performance, including Microsoft with their new Azure Linux base built on Fedora and desiring an x86-64-v3 baseline for their purposes.
After months being debated and waiting on more performance data for the Fedora Engineering and Steering Committee (FESCo) to evaluate, the members have now decided to reject this change for Fedora 45. FESCo will allow the change to be re-submitted for Fedora 46 when additional performance data is provided. They also are seeking details on how the install media would be handled in this x86-64-v3-supported world.
So, sadly, there will not be x86-64-v3 packages for Fedora 45 this year but hope next year with Fedora 46 for better embracing the hardware of this past decade.
Key points
- Fedora's x86-64-v3 plans have been delayed, but may be reconsidered for Fedora 46.
- The x86-64-v3 micro-architecture feature level is for Intel and AMD processors of roughly the past decade or longer.
- Some Linux distributions like RHEL 10 already require x86-64-v3 as a sane default.
If the x86-64-v3 proposal is reconsidered for Fedora 46, users with newer hardware may see better performance. This could also benefit companies like Microsoft who are using Fedora as a base for their Azure Linux platform.
The delay of x86-64-v3 packages for Fedora 45 may impact users who want to take advantage of better performance on newer hardware. This could also lead to a longer wait for users who want to see the benefits of x86-64-v3 on Fedora 46.
