NVIDIA confirmed today that it has taped out six distinct "Rubin" chips, which signals something more than a typical product refresh. Company CEO Jensen Huang, speaking during a visit to Taiwan, said NVIDIA already handed multiple Rubin designs to TSMC and that those dies are now entering fab qualification ahead of trial production. Rubin is intended to be a platform-level upgrade, rather than a simple GPU update, with changes extending across processors, networking gear, and interconnect silicon. Customers and cloud operators will be watching closely as NVIDIA prepares what it describes as the next major compute platform. According to Jensen, the taped designs include a dedicated CPU, new GPU variants, a scale-up NVLink switch, and a silicon photonics processor aimed at improving rack-scale connectivity and off-chip optics.

Rubin will adopt chiplet partitioning for the first time in NVIDIA's product line and is planned for TSMC's N3P process with CoWoS-L packaging. Memory is expected to transition to next-generation HBM4 stacks to sustain higher bandwidth, featuring a custom base die. The physical compute die layout will utilize a larger reticle area compared to the current generation. NVIDIA says it is coordinating hardware changes with software updates, including compiler and runtime improvements that will leverage the new topology. The company projects market introductions around 2026 for Rubin and 2027 for Rubin Ultra, depending on trial production and yields. Early validation is already underway, covering thermal, power, and interconnect scenarios. The Rubin transition from Blackwell is shaping up to be a big step, and in the new generation of AI token factories , we need more powerful chips with million-scale data centers.
