For years, Oculink, a high-speed external connection designed for gamers, has struggled for recognition. Unlike its well-known rival, Thunderbolt, Oculink lacked widespread support from major PC manufacturers, hindering its potential. Now, a surprising champion has emerged: Framework, the innovative modular PC company.
Framework announced plans to develop an Oculink Dev Kit, with full integration into the Framework Laptop 16 slated for later this year. This isn’t just a minor addition; it represents the most significant endorsement Oculink has received in its pursuit of becoming a viable external graphics solution.
The challenge with powerful gaming graphics lies in heat dissipation. Desktop computers and larger laptops can manage this effectively, but squeezing that power into a slim, portable design is incredibly difficult. The solution? Move the graphics processing outside the laptop itself, requiring a robust, high-speed connection.
While Thunderbolt dominates Intel-based laptops and USB4 serves a similar function in AMD Ryzen systems, both rely on copper signaling and can come with licensing costs. Oculink, being open source, utilizes optical connections, reducing the need for extensive cooling. However, its adoption has been slow, with limited support from both PC manufacturers and peripheral makers.
Framework is boldly stepping forward to change that. At a recent launch event in San Francisco, the company showcased a working proof-of-concept for Oculink integration. This demonstrates a commitment to the standard that few others have shown.
The core of Framework’s approach lies in the Laptop 16’s unique Expansion Bay. This allows for the connection of external discrete graphics modules via an internal PCI Express x8 connection. Interestingly, Framework’s customers and internal developers independently began exploring Oculink connectors, highlighting a shared interest in the technology.
Framework has created an Oculink adapter board that fits within the Expansion Bay Shell, providing an external Oculink connector. This opens up two possibilities: a Graphics Module Oculink Dock, designed to house Framework’s own graphics modules for improved cooling and a lighter laptop experience, and a PCIe Oculink Dock, a more traditional external GPU docking station compatible with standard graphics cards.
Framework’s implementation exposes the full Oculink 8i (128Gbps) interface, exceeding the 120Gbps unidirectional graphics mode of Thunderbolt 5. This marks the first time a laptop manufacturer has offered an 8-lane Oculink interface, a significant leap forward for the standard.
Historically, Oculink has been relegated to lesser-known devices like the GPD G1 dock and GMKtec NucBox M8. While technologies like CopprLink offer even greater bandwidth, they lack any meaningful industry support. Framework’s involvement provides Oculink with a recognizable brand and the potential for broader appeal.
Beyond Oculink, Framework also unveiled enhancements to the Laptop 16, including a one-piece haptic touchpad, a new “translucent smoke” gray bezel, and a Ryzen 5 340 processor option. The Ryzen 5 model is available for pre-order in both pre-built and DIY configurations.
