TH3P4G3 Thunderbolt 3 eGPU Dock
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 enclosures12.

Framework Compatibility
| Model | Status | Notes |
|---|---|---|
| Framework Laptop 13 (Intel 11th/12th/13th Gen) | Works | TB3/TB4 |
| Framework Laptop 13 (AMD Ryzen 7040) | Works1 | Confirmed (3080, top USB4 port) |
| Framework Laptop 13 (Intel Core Ultra) | Works | TB4 |
| Framework Laptop 13 (AMD Ryzen AI 300) | Works2 | HX 370, "works perfectly" |
| Framework Laptop 16 | Works | USB4 |
| Framework Laptop 12 | Incompatible | No USB4/Thunderbolt hardware |
Unlike the ADT-Link UT3G and AOOSTAR AG02 (which lack PD), the TH3P4G3 passes power through to the host and offers a downstream Thunderbolt port for chaining a USB hub or other peripherals — ideal if you want a single cable for GPU + charging + I/O1.
The TH3P4G3 uses PCIe 3.0, so a strong PCIe 4.0 GPU won't reach its full potential through this dock. If your GPU benefits from the extra ~8 Gbps, consider the ADT-Link UT3G (ASM2464, PCIe 4.0 x4). The USB4 link remains the ultimate bottleneck either way1.
