NVIDIA has recently submitted patches to the open - source Nova kernel graphics driver, taking proactive steps in anticipation of the launch of its GPU based on the Rubin architecture in 2026. The newly introduced driver incorporates the NV_PMC_BOOT_42 register, which is set to take over from the existing NV_PMC_BOOT_0 register. This register serves the crucial purpose of identifying GPU architecture and revision details.

This move is a clear indication of NVIDIA's innovative approach to GPU hardware initialization techniques. It also paves the way for the smooth release of the Rubin architecture. Moreover, the update to the Nova driver brings about a simplified code structure, making it more straightforward and easier to maintain.

In terms of the Rubin architecture itself, it will boast a multi - process node chiplet design. This design is a cutting - edge approach that allows for more efficient processing. Additionally, it will support HBM4 high - bandwidth memory, which is known for its extremely fast data transfer capabilities. Furthermore, the architecture will integrate sixth - generation NVLink interconnect technology, enabling seamless and high - speed communication between different components.
