The change can be resubmitted for Fedora 46. The x86-64-v3 microarchitecture level, covering Intel Haswell and newer or AMD Excavator and newer CPUs, would enable assumptions of AVX/AVX2, FMA, BMI2, and other newer instruction set features for better performance, similar to what RHEL 10 already requires by default. Microsoft's Azure Linux, based on Fedora, was among the parties interested in this baseline. ## Full article daily.dev links to this article rather than hosting it.

No, Fedora's Engineering and Steering Committee rejected the proposal to build x86-64-v3 optimized packages for Fedora 45. The change can be resubmitted for Fedora 46 once additional performance data is provided and details on how install media would be handled are worked out. Fedora 45 will continue using x86-64-v1 baseline packages. _Track Fedora's x86-64-v3 packaging decision on daily.dev before planning distro upgrades around CPU baseline requirements._ ### What CPUs support the x86-64-v3 microarchitecture level? x86-64-v3 covers Intel Haswell and newer, or AMD Excavator and newer processors, roughly the past decade of x86 CPUs. It assumes support for AVX, AVX2, FMA, BMI2, MOVBE, and XSAVE instruction set extensions, allowing compilers to generate faster code without needing runtime CPU feature checks. RHEL 10 already requires x86-64-v3 as its default baseline. _Developers weighing CPU baseline requirements can follow x86-64-v3 adoption news on daily.dev._ ## Similar posts on daily.dev - [Fedora Yet To Decide On x86\_64-v3 Packages For Fedora Linux 45](https://daily.dev/posts/fedora-yet-to-decide-on-x86-64-v3-packages-for-fedora-linux-45-pekuvyqfd) · Phoronix · 0 upvotes · 0 comments - [Fedora 45 To Consider Building x86\_64-v3 Packages](https://daily.dev/posts/fedora-45-to-consider-building-x86-64-v3-packages-btlqqkv0x) · Phoronix · 0 upvotes · 0 comments - [Microsoft Might Be Rebasing Azure on Fedora Linux](https://daily.dev/posts/microsoft-might-be-rebasing-azure-on-fedora-linux-v14ck4eys) · It's Foss · 0 upvotes · 0 comments - [Canonical Experimenting With x86-64-v3 Packages For Ubuntu 26.10](https://daily.dev/posts/canonical-experimenting-with-x86-64-v3-packages-for-ubuntu-26-10-e4yornlcf) · Phoronix · 1 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#performance](https://daily.dev/tags/performance), [#hardware](https://daily.dev/tags/hardware), [#fedora](https://daily.dev/tags/fedora) [View this post on daily.dev](https://daily.dev/posts/fedora-x86-64-v3-optimized-packages-pushed-back-to-at-least-fedora-46-xhno6fdpx) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Fedora x86-64-v3 Optimized Packages Pushed Back To At Least Fedora 46","url":"https://daily.dev/posts/fedora-x86-64-v3-optimized-packages-pushed-back-to-at-least-fedora-46-xhno6fdpx","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/fedora-x86-64-v3-optimized-packages-pushed-back-to-at-least-fedora-46-xhno6fdpx"},"datePublished":"2026-08-18T10:26:58.935Z","dateModified":"2026-08-18T10:27:27.968Z","description":"Fedora's Engineering and Steering Committee (FESCo) has rejected a proposal to build x86-64-v3 optimized packages for Fedora 45, citing the need for more...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/bf8eba46f575672d06c0e5135e2d3a02?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/bf8eba46f575672d06c0e5135e2d3a02?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Phoronix","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Phoronix","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/6a26ba379dd64932830aa0c9803dd7ee","url":"https://daily.dev/sources/phoronix"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/fedora-x86-64-v3-optimized-packages-pushed-back-to-at-least-fedora-46-xhno6fdpx","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"linux,performance,hardware,fedora","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Phoronix","item":"https://daily.dev/sources/phoronix"},{"@type":"ListItem","position":3,"name":"Fedora x86-64-v3 Optimized Packages Pushed Back To At Least Fedora 46"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/fedora-x86-64-v3-optimized-packages-pushed-back-to-at-least-fedora-46-xhno6fdpx#faq","mainEntity":[{"@type":"Question","name":"Will Fedora 45 ship with x86-64-v3 optimized packages?","acceptedAnswer":{"@type":"Answer","text":"No, Fedora's Engineering and Steering Committee rejected the proposal to build x86-64-v3 optimized packages for Fedora 45.
