CachyOS is an Arch-based Linux distribution specifically crafted for high performance, focusing on speed, stability, and user experience, providing superb gaming efficiency. Designed for both experienced and intermediate Linux users, it offers a powerful, customizable operating system. CachyOS employs advanced compiler optimizations (x86-64-v3/v4) and customized kernels, such as BORE, to enhance its performance.

Rolling-Releases for Continuous Updates

CachyOS uses a "rolling-release" model, providing users with continuous updates and the latest software enhancements, making it especially attractive to gamers and power users who prioritize performance and efficiency. The distribution features meticulously optimized desktop environments designed for modern hardware, ensuring users enjoy a smooth experience while browsing the web, developing applications, creating content, or gaming. Every component of CachyOS is built entirely on free and open-source software, underscoring its dedication not only to high performance but also to accessibility for a wide range of users.

Custom Compiled Kernels Included

What sets CachyOS apart from other Linux distributions is its intense focus on performance optimization. It comes preloaded with custom-compiled kernels that leverage aggressive compiler optimizations, along with finely tuned system settings designed to minimize latency and enhance responsiveness, particularly on newer CPU architectures. In contrast, a standard Arch Linux installation tends to remain minimalistic and neutral in its settings, leaving many optimization choices up to the individual user. This means that while Arch Linux provides great flexibility, it may require additional effort for those looking to squeeze out every bit of performance from their systems.

Many Desktop Environments Available:

●KDE Plasma is a comprehensive and flexible desktop environment that offers multiple styles of menus to access applications. It features the kwin window manager, and also works with Compiz. KDE Plasma also boasts an intuitive interface that allows you to easily download and install new themes, widgets, and more from the web.
●CuteFish is a sleek, modern, and efficient desktop environment built using Qt Quick and some KDE core frameworks. It has a design reminiscent of macOS.
i3 is a popular tiling window manager known for its single, self-contained configuration file and its efficient use of screen space.
●GNOME is a user-friendly desktop environment with a touch-style interface for accessing applications. While it is easy to learn, it may have limited customization options and can be difficult to configure.
●Openbox is a highly popular window manager known for its excellent documentation and a wide selection of available themes.
●Wayfire is a Wayland compositor based on wlroots that balances customization, extendibility, and aesthetics.
●XFCE is a lightweight and flexible desktop environment with a traditional drop-down/pop-up menu for accessing applications, and is compatible with Compiz. Customization may require some effort to match personal preferences.
●LXQt is a lightweight desktop environment formed from the merger of the LXDE and Razor-qt projects and built with Qt.
●bspwm: Tiling WM for X11, written in C, dynamic layout (tiling, stacking, tabbing), windows represented as binary tree leaves.
●Cinnamon is a desktop environment for Linux that balances advanced features with a traditional user experience.
●UKUI is a lightweight desktop environment that is efficient and works well on older computers. It uses both GTK and Qt technologies, and has a visual appearance similar to Windows 7, making it user-friendly for new Linux users.
●Hyprland is a visually pleasing Wayland compositor that uses dynamic tiling. It comes with preconfigured dotfiles.
●Budgie is a simple and elegant desktop environment built using the GTK toolkit. It is designed to provide a modern, attractive, easy-to-use interface that is highly configurable.
●LXDE (Lightweight X11 Desktop Environment) is a fast and energy-saving desktop environment designed to be used on older computers and resource-constrained systems. It uses Openbox as its default window manager and focuses on providing a simple, clean and user-friendly interface.
●Mate Desktop is a traditional desktop environment forked from GNOME 2. It is characterized by its classic look and feel and a simple, intuitive user interface. Mate provides an easy-to-use and highly customizable desktop experience for users who prefer a more classic look and feel.

Linux Kernels:

The CachyOS kernels use different Schedulers and patches to improve performance. The following schedulers are supported:

    ● BORE (Burst-Oriented Response Enhancer) CPU Scheduler by firelzrd (BORE) - linux-cachyos
    ● Standard Scheduler Completely Fair Scheduler (CFS) - linux-cachyos-cfs
    ● BitMap Queue (BMQ) Alfred Chen Scheduler - linux-cachyos-bmq
    ● Priority and Deadline based Skiplist multiple queue scheduler (PDS) - Alfred Chen Scheduler » linux-cachyos-pds
    ● Task Type Scheduler by Hamad Marri (TT) - linux-cachyos-tt

All kernels are built in two versions (x86_64 and x86_64_v3), and LLVM/LTO-enabled kernels are included in the cachyos repo.

Understanding of Linux is Recommended

CachyOS is recommended for users with an understanding of Linux, making it more suitable for intermediate to advanced users. Although it features a user-friendly graphical installer and adopts sensible defaults to streamline the installation process, its underlying Arch-based architecture expects users to be comfortable with tasks such as troubleshooting, reading extensive documentation, and occasionally performing manual interventions following system updates. This empowers users who are eager to delve deep into customization and optimization while providing a robust platform for seasoned Linux enthusiasts.

Geek Verdict

CachyOS stands out as an excellent, high-performance distribution built on Arch Linux, specifically designed for gaming and cutting-edge hardware. It boasts a collection of optimized packages and features a custom kernel equipped with the BORE scheduler, which significantly boosts performance and responsiveness. Furthermore, CachyOS offers seamless automatic hardware detection, ensuring an exceptionally smooth user experience that surpasses many conventional alternatives.
