TinyCorp Achieves Milestone with Nvidia GPUs on ARM MacBooks
In a significant development, TinyCorp has successfully transitioned its work on AMD graphics cards to accommodate Nvidia’s RTX 30, 40, and 50 series for use with ARM-based MacBooks.
This breakthrough allows these graphics cards to interface through external GPU docking stations utilizing the USB4 and Thunderbolt 4 standards.
However, it is crucial to note that these drivers are tailored explicitly for artificial intelligence (AI) development and do not provide display functionalities on MacBook devices.
On social media platform X, TinyCorp showcased this innovation along with installation instructions designed for AI developers. They shared an image featuring a MacBook Pro M3 Max executing Tinygrad via an RTX GPU connected to an ADT-UT3G dock employing USB4 technology.
Currently, support is limited to the RTX 30, 40, and 50 series graphics cards. Although TinyCorp suggests that the RTX 20 series may function with additional user adjustments, the core issue lies in their drivers being exclusively compatible with Nvidia GPUs that house a GPU system processor, thus excluding GTX-series graphics cards.
Remarkably, AMD GPUs utilizing RDNA 2, 3, and 4 architectures are reportedly supported as well.
Installation Insights
For the tech-savvy audience, TinyCorp detailed the installation process as follows:
- Ensure the use of an ADT-UT3G dock with a compatible 30/40/50 series GPU.
- Disable System Integrity Protection (SIP).
- Install the driver via the command:
extra/usbgpu/tbgpu. - Install the NVK compiler using:
brew install tinymesa. - Conduct tests with the command:
DEBUG=2 NV_NAK=1 NV=1 python3 test/test_tiny.py TestTiny.test_plus.
Facilitating the operation of Nvidia GPUs on Apple devices has historically proven to be a formidable challenge, particularly following Apple’s departure from Intel processors in favor of its proprietary M-series chips, which rely exclusively on a robust integrated GPU.
This transition eliminated the pressing need for Nvidia or AMD driver integration within the ARM-compatible iterations of macOS.
Consequently, developers and users have been compelled to create custom drivers to enable functionality between macOS and external Nvidia or AMD graphics cards.
TinyCorp, however, leveraged its prior expertise—having previously developed drivers for external AMD graphics cards on Apple silicon with USB3—to bridge this gap.
The endeavor has likely benefited from the intrinsic advantages of USB4/Thunderbolt 4, which is engineered for external GPU solutions and comes with native PCIe support, thus easing the implementation.
Furthermore, the substantial bandwidth enhancements offered by USB4/Thunderbolt 4 over traditional USB3 standards cannot be overlooked.
Implications for AI Development
This innovative capability stands to significantly benefit those in the AI sector. Running Nvidia GPUs on ARM MacBooks provides a marked increase in performance for local large language models (LLMs) and other AI applications, particularly with cards like the RTX 5090, which outperform Apple’s M-series GPUs in computational tasks.
