CachyOS, the performance-tuned Linux distribution built on Arch, has posted decisive benchmark leads over upstream Arch Linux, Ubuntu 26.04 LTS, and Pop!_OS 24.04 when tested on System76's flagship Thelio Major workstation, according to a review published by Phoronix.
The benchmarks were run on a Thelio Major equipped with AMD's Ryzen Threadripper 9000 series processors and an optional Radeon AI PRO R9700 graphics card, forming an entirely open-source AMD software stack from CPU to GPU.
Why CachyOS pulls ahead
CachyOS differentiates itself from a stock Arch installation through several layers of optimisation: packages compiled against the x86-64-v3 and x86-64-v4 instruction sets to take advantage of modern CPU microarchitectures, a custom kernel configuration, and alternative task schedulers tuned for throughput rather than default Linux fairness heuristics. On a workstation-class platform like the Threadripper 9000, which offers a high core count and wide memory bandwidth, these software-level tweaks translate into measurable performance gains.
Pop!_OS trails its own hardware vendor's optimised offering
Perhaps the most notable detail from the Phoronix testing is that Pop!_OS — developed by System76 specifically for its own hardware lineup — fell behind CachyOS on the Thelio Major. The result suggests that even a distribution purpose-built for a vendor's machines does not automatically deliver the best possible performance when deeper compiler and kernel-level tuning is available from alternative projects.
Ubuntu 26.04 LTS and vanilla Arch Linux also trailed, though neither distribution makes aggressive per-architecture optimisation a core part of its design philosophy the way CachyOS does.
Who benefits most
The performance delta is most consequential for users running compute-intensive workloads on premium workstation hardware — continuous integration pipelines, large-scale data analysis, and local AI inference, among other tasks. In these scenarios, even modest per-benchmark percentage gains can compound meaningfully over time or across parallel jobs.
For casual desktop use, the differences are unlikely to matter, but professionals who invest in Threadripper-class silicon are precisely the audience most likely to care about extracting every cycle of throughput from the platform.
A broader trend worth watching
CachyOS's strong showing reflects a wider pattern in the Linux ecosystem: performance-oriented distributions are gaining traction among power users who want measurable optimisation benefits without manually rebuilding packages or hand-tuning a base installation. As workstation hardware grows more specialised — with higher core counts, wider SIMD instruction sets, and heterogeneous compute architectures — the demand for distributions that exploit those capabilities out of the box is likely to grow.
For IT teams evaluating Linux workstation deployments, the Phoronix review offers a useful data point: the choice of distribution can materially affect performance on high-end hardware, and vendor affiliation alone is no guarantee of optimal throughput.
根據 Phoronix 發布的一篇評測，在 System76 旗艦級 Thelio Major 工作站上進行測試時，以 Arch 為基礎並針對效能調校的 Linux 發行版 CachyOS，在基準測試中取得了決定性的領先，超越了上游的 Arch Linux、Ubuntu 26.04 LTS 和 Pop!_OS 24.04。
基準測試在一台配備 AMD Ryzen Threadripper 9000 系列處理器以及可選配的 Radeon AI PRO R9700 顯示卡的 Thelio Major 上進行，構成了從中央處理器到圖形處理器完全開源的 AMD 軟件堆棧。
CachyOS 領先的原因
CachyOS 透過多層次的優化，將其與標準 Arch 安裝區分開來：軟件套件是針對 x86-64-v3 和 x86-64-v4 指令集編譯的，以充分利用現代 CPU 微架構；採用了自訂的核心配置；以及使用了為吞吐量而非預設 Linux 公平性啟發式算法調校的替代任務排程器。在像 Threadripper 9000 這類擁有高核心數和寬廣記憶體頻寬的工作站級平台上，這些軟件層面的調整轉化為了可衡量的效能提升。
Pop!_OS 落後於自身硬件供應商的優化產品
Phoronix 測試中最值得注意的細節或許是，Pop!_OS——由 System76 專為其自身硬件系列開發的發行版——在 Thelio Major 上落後於 CachyOS。這個結果表明，即使是一個專門為某供應商機器打造的發行版，當有替代項目提供更深層次的編譯器和核心級調校時，它也未必能自動提供最佳效能。
Ubuntu 26.04 LTS 和原版 Arch Linux 也同樣落後，不過這兩個發行版都沒有像 CachyOS 那樣，將針對特定架構的積極優化作為其設計哲學的核心部分。
誰受益最大
效能差異對於在高端工作站硬件上運行運算密集型工作負載的使用者來說最為重要——持續整合 pipeline、大規模數據分析和本地 AI 推理等任務均屬此列。在這些場景中，即使每次基準測試只有適度的百分比提升，隨著時間推移或跨並行任務的累積，也能帶來顯著的效益。
對於日常桌面使用，這些差異可能無關緊要，但投資於 Threadripper 級別硬件的專業人士，恰恰是最有可能關心從平台榨取每一分吞吐量的受眾。
一個值得關注的更廣泛趨勢
CachyOS 的出色表現反映了一個更廣泛的模式：面向效能的發行版正受到進階用戶的青睞，他們希望獲得可衡量的優化效益，而無需手動重新編譯套件或對基礎安裝進行繁瑣的手工調整。隨著工作站硬件變得更加專業化——擁有更高的核心數、更寬的 SIMD 指令集和異構計算架構——對能夠開箱即用發揮這些能力的發行版的需求很可能增長。
對於評估 Linux 工作站部署的 IT 團隊而言，Phoronix 的評測提供了一個有用的數據點：發行版的選擇能夠顯著影響高端硬件的效能，而僅憑與供應商的關聯並不能保證獲得最佳吞吐量。
