Verdict — Decent Last Resort Graphics Boost
The Radeon RX 7600M XT is uncommon and for good reason. Unfortunately, it hasn't aged very well when compared to modern budget Nvidia GPUs like the GeForce RTX 4050 which can oftentimes outperform our AMD solution while pulling in just half the power. It targets 1080p gaming, but the latest titles are already proving to be overwhelming. These drawbacks would have been more acceptable for the AD-GP1 if it weren't for its steep $400 to $500 retail price.
With that said, the AD-GP1 is still an improvement when paired to laptops or mini PCs powered by integrated Intel or AMD graphics even if the underlying Radeon RX 7600M XT GPU isn't the newest or most efficient. It can be seen as a portable last resort solution if there are no other ways of boosting graphics performance from your existing PC.
Pros
Cons
Price and Availability
GMKtec is now shipping the AD-GP1 eGPU docking station as reviewed for $465 USD.
The GMK AD-GP1 is a small external GPU (eGPU) solution with an integrated Radeon 7600M XT. It competes directly with other mini eGPUs including the GPD G1 which also utilizes the same AMD graphics.
Specifications
Case
The unit should be positioned horizontally due to how the ventilation grilles are designed. While the unit itself is reasonably small and about the size of an Intel NUC Canyon, its bulky 240 W power brick is just as large and arguably an eyesore.
Connectivity
The dock can output up to four external displays via DisplayPort 2.0 or HDMI 2.1. Note that the single USB-C 4.0 port cannot be used as a DisplayPort as it is mainly for connecting to the host PC (if OcuLink is not compatible) or for 100 W Power Delivery charging.
Performance
Testing Conditions
Our host PC is the GMK EVO-X1 mini PC with the Ryzen AI 9 CPU as reviewed here. The model is notable for its integrated OcuLink port to be fully compatible with the AD-GP1. Otherwise, users can connect most PCs to the dock via USB-C 4.0 for slightly slower performance.

GPU Performance
Raw performance sits in between the GeForce RTX 4050 and RTX 4060. If running more demanding DX12 titles with ray-tracing, however, the Radeon RX 7600M XT falls behind significantly due to its weak RT cores when compared to Nvidia. This is exemplified by our very low score in the RT-specific Port Royal benchmark.
Overall performance is still roughly 2x to 2.5x faster than the integrated Radeon 890M in most modern AMD Zen 5 laptops or mini PCs.

Gaming Performance
Older DX11 titles run well on the Radeon RX 7600M XT. Newer titles, however, show the AD-GP1 struggling to keep up even when on low 1080p settings. For example, Monster Hunter Wilds can't crack the average 60 FPS mark on the lowest 1080p settings without the help of FSR or frame generation. Titles that rely or force ray tracing, such as Indiana Jones and the Great Circle, are essentially unplayable. Other demanding titles like Marvel Rivals show difficulty maintaining 60 FPS at 1080p when characters and effects fill the screen for a very unsteady experience even with FSR enabled.

System Noise
The AD-GP1 does a great job at remaining quiet when running undemanding loads to be generally unnoticeable. However, fan noise steadily picks up when gaming before stabilizing at 57 dB(A) to be as loud as many gaming laptops.

Temperature
Stress Test
The GPU would stabilize at 2341 MHz, 72 C, and 156 W when running Cyberpunk 2077 to represent typical gaming conditions. A temporary maximum of 200 W can be recorded when running FurMark meaning that the 240 W AC adapter is sufficient for powering the dock in addition to most devices connected via USB-C PD.
Keep in mind that the GeForce RTX 4050 GPU in most laptops demand just 80 W or less while providing similar performance to the AD-GP1.
