Ubuntu 26.10 and CachyOS run the Linux 7.3 kernel, while Fedora 45 is still on 7.2 but will get 7.3 as a post-release update. Fedora 45 and CachyOS default to GCC 16.2, while Ubuntu 26.10 uses GCC 15. Graphics tests were skipped because the Radeon RX 9070 GRE fell back to LLVMpipe on Ubuntu 26.10, where the AMDGPU driver caused the display to stop working at boot, a regression versus Ubuntu 26.04 LTS requiring a 'nomodeset' workaround. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why did my AMDGPU driver cause the display to stop working at boot on Ubuntu 26.10 with a Radeon RX 9070 GRE? This is a known regression on Ubuntu 26.10 compared to Ubuntu 26.04 LTS, where the AMDGPU driver loading at boot with a Radeon RX 9070 GRE causes the display to stop working. A workaround is to boot with the 'nomodeset' kernel parameter, which forces a fallback to LLVMpipe software rendering instead of hardware acceleration. _Anyone chasing AMDGPU boot regressions can track real-world distro fixes on daily.dev._ ### What Linux kernel version do CachyOS and Ubuntu 26.10 ship by default? Both CachyOS and Ubuntu 26.10 ship the Linux 7.3 kernel as their latest stable release. Fedora Workstation 45, by contrast, launches on Linux 7.2 but is expected to roll out Linux 7.3 as a post-release update. _Developers weighing distro upgrades can compare kernel and toolchain versions like these on daily.dev._ ### Does Fedora 45 or Ubuntu 26.10 use a newer GCC compiler by default? Fedora 45 defaults to GCC 16.2, the same compiler version used by CachyOS, while Ubuntu 26.10 sticks with the older GCC 15. This toolchain difference is one of the distinctions tested when comparing out-of-the-box performance across CachyOS, Fedora 45, and Ubuntu 26.10 on AMD Ryzen 9 hardware. _Picking a distro for a new build is easier with toolchain comparisons like this on daily.dev._ ## Similar posts on daily.dev - [CachyOS Linux Performance Leading Over Ubuntu 26.04 LTS, Fedora Workstation 44](https://daily.dev/posts/cachyos-linux-performance-leading-over-ubuntu-26-04-lts-fedora-workstation-44-gxoydxiws) · Phoronix · 1 upvotes · 0 comments - [CachyOS Continues Delivering Leading Performance Over Ubuntu 25.10, Fedora Workstation 43](https://daily.dev/posts/cachyos-continues-delivering-leading-performance-over-ubuntu-25-10-fedora-workstation-43-rxanlkchq) · Phoronix · 1 upvotes · 0 comments - [CachyOS Outperforming Windows 11, Ubuntu & Fedora On AMD Ryzen AI 9 HX 470](https://daily.dev/posts/cachyos-outperforming-windows-11-ubuntu-fedora-on-amd-ryzen-ai-9-hx-470-0dfj4rl4a) · Phoronix · 0 upvotes · 0 comments - [CachyOS Delivers Lead Over Arch Linux, Pop\!\_OS & Ubuntu On System76 Thelio Major](https://daily.dev/posts/cachyos-delivers-lead-over-arch-linux-pop-os-ubuntu-on-system76-thelio-major-ecpe9diiu) · Phoronix · 1 upvotes · 0 comments - [CachyOS beats Windows 11 in Cyberpunk 2077 and Space Marine 2 in a new gaming benchmark](https://daily.dev/posts/cachyos-beats-windows-11-in-cyberpunk-2077-and-space-marine-2-in-a-new-gaming-benchmark-zkck5ak8v) · XDA Developers · 1 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#ubuntu](https://daily.dev/tags/ubuntu), [#fedora](https://daily.dev/tags/fedora) [View this post on daily.dev](https://daily.dev/posts/cachyos-vs-fedora-45-vs-ubuntu-26-10-performance-on-amd-ryzen-9-7osyhiyo6) ```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":"CachyOS vs. Fedora 45 vs. Ubuntu 26.10 Performance On AMD Ryzen 9","url":"https://daily.dev/posts/cachyos-vs-fedora-45-vs-ubuntu-26-10-performance-on-amd-ryzen-9-7osyhiyo6","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/cachyos-vs-fedora-45-vs-ubuntu-26-10-performance-on-amd-ryzen-9-7osyhiyo6"},"datePublished":"2026-10-28T15:01:30.929Z","dateModified":"2026-10-28T15:20:39.208Z","description":"Phoronix ran CPU and system benchmarks comparing CachyOS, Fedora Workstation 45 and Ubuntu 26.10 on an AMD Ryzen 9 9900X3D2 desktop.
