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

Introduction

The System76 Thelio Major represents the latest evolution in high-end Linux workstations. Following the redesigned Thelio Mira, which we reviewed a few weeks ago, the Major takes performance to the next level with AMD's latest Threadripper processors and Radeon AI PRO graphics. Built in Colorado, this all-AMD machine is not only powerful but also champions the open-source philosophy, delivering a workstation that is both transparent and customizable.

Design and Build Quality

The Thelio Major shares the same refreshed chassis as the Mira, a sleek and functional enclosure crafted by System76. The new case improves airflow and thermal management, crucial for the high-core-count Threadripper CPUs. Every unit is assembled in the United States, ensuring quality control and supporting local manufacturing.

Performance and Hardware Specifications

Processor and Graphics

At the heart of the Thelio Major is the AMD Ryzen Threadripper 9000 series, offering up to 96 cores for compute-intensive tasks such as 3D rendering, simulation, and software compilation. Paired with the AMD Radeon AI PRO R9700 graphics, this workstation handles professional AI workloads, video editing, and multi-monitor setups with ease. The all-AMD combination ensures optimal driver support and compatibility under Linux.

Memory and Storage

The system supports up to 128GB of DDR5 ECC RAM, providing reliability for mission-critical applications. Multiple PCIe 5.0 NVMe drives deliver lightning-fast storage, with options for RAID configurations. Users can customize storage to match their workflow needs.

Open-Source Commitment

System76 is renowned for its dedication to open-source software and hardware. The Thelio Major uses coreboot as its firmware, a free and open-source alternative to proprietary BIOS. Every driver and component is selected for strong Linux compatibility, and the company contributes code upstream to benefit the entire community. This transparency allows users to audit and modify their system's firmware, enhancing security and repairability.

Software and Ecosystem

The workstation ships with Pop!_OS, System76's own Linux distribution based on Ubuntu, fully optimized for the hardware. It includes the COSMIC desktop environment, offering a modern, tiling-window workflow. The entire software stack is open-source, from the kernel to the user interface, empowering developers and researchers to tailor every aspect of their environment.

Target Users and Use Cases

The Thelio Major is built for professionals who demand extreme performance without sacrificing principles. Ideal users include data scientists running machine learning models, video editors working with high-resolution footage, engineers performing CAD simulations, and software developers compiling large codebases. The all-AMD architecture also appeals to those who prefer a homogeneous hardware stack for stability.

Comparison with Thelio Mira

While the Thelio Mira (see our review) offers excellent performance with the AMD Ryzen 9000 series, the Major steps up with Threadripper processors. The Mira suits mainstream workloads, while the Major is for heavy multitasking and parallel processing. Both share the same case design and open-source firmware.

Conclusion

The System76 Thelio Major is a testament to the possibilities of open-source hardware and software. Combining cutting-edge AMD technology with a commitment to freedom, it offers a top-tier workstation for professionals who value both performance and principles. Whether for deep learning, content creation, or scientific research, this machine delivers where it matters most.
