AI startup TinyCorp posted on the X platform, revealing that the company has manufactured an eGPU expansion board suitable for Apple chips and successfully connected a Galaxy RTX 5060 graphics card to an Apple Mac mini. The company announced that the corresponding eGPU expansion board will be officially launched in the second quarter of this year and will also integrate power management functions.
According to information disclosed by TinyCorp, the solution is based on the ADT-Link expansion adapter, which can convert the Mac’s Thunderbolt interface into a PCIe bus interface for connecting to the GPU, achieving a bandwidth of approximately 40Gbps (approximately 5GB/s bidirectional), which can be used for computing tasks such as AI large language model inference.
On the software level, in order to address the lack of native support for AMD and Nvidia GPUs in ARM macOS, TinyCorp also wrote a dedicated driver in Python to enable the graphics card to function properly in the system.
It should be noted that this solution is currently mainly aimed at “pure computing” scenarios. The GPU is used as a raw computing device through the PCIe memory mapping interface and cannot be used for graphics output or graphics acceleration tasks.
