System76 Thelio Major: A Redesigned All-AMD Open-Source Linux Powerhouse

Introduction

Only a few weeks ago, we had the opportunity to examine the redesigned System76 Thelio Mira, a Linux desktop that introduced a fresh chassis design and harnessed the power of the AMD Ryzen 9000 series. Now, System76 has unveiled a more potent sibling: the System76 Thelio Major. This newly reconfigured workstation builds upon the same modern case aesthetic found in the Mira while packing significantly more muscle under the hood. Designed for professionals who demand uncompromising performance, the Thelio Major comes equipped with the AMD Ryzen Threadripper 9000 series processors and AMD Radeon AI PRO R9700 graphics. The result is a fully all-AMD, open-source, high-end Linux workstation that competes with the best in its class.

The Thelio Mira Foundation

Before diving into the Major, it’s worth recalling the System76 Thelio Mira, which first demonstrated the company’s commitment to a clean, functional, and user-upgradable chassis. The Mira offered a glimpse of what a modern Linux desktop could look like when designed from the ground up for both aesthetics and airflow. That same philosophy carries over to the Thelio Major, but with a focus on scalability and raw computing power.

Redesigned Chassis and Build Quality

The Thelio Major inherits the same updated case design as the Mira, a significant departure from earlier System76 enclosures. The chassis is crafted from aluminum and steel, providing a sleek, minimalist look that fits equally well in a studio, lab, or server room. The internal layout prioritizes thermals and accessibility: large intake vents on the front and side panels allow for ample airflow, while tool-less drive bays and easy-access expansion slots simplify upgrades.

System76 manufactures all Thelio models in their Colorado facility, ensuring quality control and the ability to customize each unit to individual specifications. The Thelio Major’s case supports standard ATX power supplies and motherboards, but it comes pre-configured with reliable components chosen by the System76 engineering team. The entire system is designed to be open and repairable, aligning with the company’s open-source ethos.

Under the Hood: AMD Ryzen Threadripper 9000 and Radeon AI PRO R9700

At the heart of the Thelio Major lies the AMD Ryzen Threadripper 9000 series processor. These chips bring massive multi-core performance, ideal for demanding workloads such as video editing, 3D rendering, scientific simulations, and software compilation. With up to 96 cores and 192 threads (depending on the specific model chosen), the Thelio Major can handle parallel tasks with ease. The Threadripper platform also supports PCIe 5.0, enabling high-speed connectivity for the latest GPUs and storage devices.

Complementing the CPU is the AMD Radeon AI PRO R9700 graphics card. This professional-grade GPU delivers exceptional performance for compute workloads, including AI/ML training, data analysis, and graphics rendering. The Radeon AI PRO R9700 supports hardware-accelerated ray tracing and offers generous VRAM, making it suitable for both creative professionals and researchers. By pairing an all-AMD architecture, System76 ensures seamless driver integration and optimal performance under Linux.

AMD Radeon AI PRO R9700: A Professional Workhorse

The AMD Radeon AI PRO R9700 is not your typical consumer GPU; it is built for stability and longevity in demanding environments. With support for error-correcting code (ECC) memory and certified drivers for major Linux distributions, it provides the reliability needed for mission-critical tasks. The card’s AI accelerators and large memory pool make it particularly adept at machine learning inference and model training, all while maintaining full open-source driver support through the AMD ROCm stack.

An Open-Source Linux Workstation

What truly sets the Thelio Major apart is its commitment to open-source firmware and software. System76 ships every Thelio with coreboot, an open-source BIOS replacement that improves boot times and security. Combined with a fully open-source graphics driver stack (AMD’s open-source kernel drivers and Mesa), the entire platform can be audited, customized, and controlled by the user. The Thelio Major comes pre-installed with Pop!_OS, System76’s own Linux distribution based on Ubuntu, which includes the latest kernel optimizations for AMD hardware.

This open-source approach extends to the hardware design files themselves. System76 publishes schematics and mechanical drawings for their chassis, allowing the community to modify and improve upon the design. It’s a rare level of transparency in the workstation market, appealing to developers, security-conscious professionals, and open-source advocates alike.

Performance and Target Audience

The Thelio Major is engineered for users who need uncompromising performance from a Linux workstation. Whether you are a 3D animator using Blender, a data scientist training neural networks, or a developer compiling large codebases, the combination of Threadripper 9000 and Radeon AI PRO R9700 delivers exceptional throughput. The all-AMD architecture also avoids the driver fragmentation that can occur with mixed-vendor systems, resulting in a more stable and predictable experience under Linux.

Compared to the Thelio Mira, which targets the upper mid-range market, the Thelio Major occupies the high-end workstation niche. It competes directly with offerings from Dell, HP, and Lenovo, but with the added advantage of full open-source firmware and a manufacturer that prioritizes customer freedom. The price reflects the premium components, but for those who require maximum performance, the Thelio Major is a compelling choice.

Conclusion

The redesigned System76 Thelio Major successfully elevates the all-AMD, open-source Linux workstation concept to new heights. Building on the modern chassis introduced with the Mira, it packs the formidable AMD Ryzen Threadripper 9000 and Radeon AI PRO R9700 to tackle the most demanding professional workloads. Manufactured in Colorado and backed by System76’s commitment to open source, the Thelio Major is more than just a powerful machine—it’s a statement about the future of computing. For anyone who wants a high-end Linux workstation without proprietary lock-in, the Thelio Major is a top contender.
