The ADT-Link UT3G is a bare-board USB4 eGPU adapter (no enclosure) built around the ASMedia ASM2464PD controller, which exposes a PCIe 4.0 x4 slot rather than the PCIe 3.0 x4 limit of older Thunderbolt controllers. It is ranked the fastest USB4 eGPU adapter on eGPU.io and is recommended by Framework community members as the best-performing USB4 option for AMD-based Frameworks. Note: there is no enclosure or power delivery — you supply your own PSU and GPU.
The AOOSTAR AG02 is an affordable USB4 eGPU enclosure (ASMedia controller) that accepts a desktop graphics card and connects over a USB4/TB4 link. It is confirmed working with Framework 13 (AMD Ryzen AI 300 / HX 370) and Framework 16 setups, though community reports note it can be "iffy" with certain cable and card combinations.
The Framework 16 to MXM GPU Adapter is an open-source community project by Joe Shapiro (GitHub: JJ-Shapiro) that aims to create a custom PCB adapter allowing standard MXM mobile GPU modules to be used in the Framework Laptop 16's expansion bay. If successful, it would enable users to install a wide range of mobile GPUs — including Nvidia MXM modules such as the mobile RTX 4090 — into their Framework 16.
The Framework OCuLink Dev Kit is a modular adapter and dock system for the Framework Laptop 16, previewed on April 21, 2026 at Framework's next-gen hardware event. It uses the OCuLink 8i interface to provide up to 128 Gbps bidirectional throughput for external PCIe devices, making the Framework Laptop 16 the first laptop to expose an 8-lane OCuLink interface. The kit enables connecting external GPUs, network cards, video capture cards, and other PCIe peripherals with very little performance penalty compared to a desktop PC.
The Minisforum DEG1 is an OCuLink-to-PCIe x16 dock that connects a desktop graphics card to a host over a native OCuLink connection — bypassing the Thunderbolt/USB4 protocol overhead entirely. On the Framework Laptop 16 it pairs with the community M.2-to-OCuLink Expansion Bay adapter (or the official OCuLink Dev Kit) to deliver full PCIe bandwidth. Framework 16 users report it as more stable than USB4 eGPU enclosures like the AOOSTAR AG02, and it ships with a longer, more compatible cable.
The OcuLink eGPU Expansion Bay Module is a community-developed hardware project that adds OCuLink (Optical-Copper Link) external GPU connectivity to the Framework Laptop 16 via its Expansion Bay. OCuLink provides a direct PCIe connection to the laptop's GPU slot, offering significantly higher bandwidth than USB4/Thunderbolt — up to ~63 Gbps for 4i (x4 PCIe 4.0) and ~126 Gbps for 8i (x8 PCIe 4.0), compared to ~32 Gbps for USB4. The project was initiated in June 2023 after Framework CEO Nrp greenlit community exploration of OCuLink for the Expansion Bay, and has since evolved through multiple design approaches, commercial preorders, and open-source hardware iterations.
The Razer Core X is a Thunderbolt 3 eGPU enclosure that accepts a full-size desktop PCIe graphics card and provides up to 100W of power delivery back to the host laptop. It is the most widely used and best-documented eGPU enclosure in the Framework community, confirmed working across the Framework 13 (Intel and AMD) and the Framework 16. A variant, the Razer Core X Chroma, adds a gigabit Ethernet port and a 4-port USB-A hub.
The Sonnet Breakaway Box 750ex is a Thunderbolt 3 eGPU enclosure built around an Intel DSL6540 controller (PCIe 3.0 x4 to Thunderbolt), pairing a 750W power supply with support for high-end double-width graphics cards. It is documented working with a Framework Laptop 13 (Ryzen 7840U) driving an RTX 4070 on Windows, with users achieving the full 32 Gbps PCIe tunnel using an active Thunderbolt 4 cable.
The TH3P4G3 is a Thunderbolt 3 eGPU dock (bare board) using a PCIe 3.0 interface, popular as a budget one-cable option because it supports power delivery to the host and Thunderbolt daisy-chaining. Framework community members report it working "like a charm" on AMD Framework 13 laptops after switching away from problematic Lenovo enclosures.
