NVIDIA CEO Jensen Huang delivered a keynote speech at the NTU (National Taiwan University) Sports Center on June 2. As per a report from TechNews, during the speech, he unveiled the new generation Rubin architecture, showcasing NVIDIA’s accelerated rollout of new architectures, which became the highlight of the evening.

While discussing NVIDIA’s next-generation architecture, Huang mentioned the Blackwell Ultra GPU and indicated that it may continue to be upgraded. He then revealed that the next-generation architecture following Blackwell will be the Rubin architecture.

The Rubin GPU will feature 8 HBM4, while the Rubin Ultra GPU will come with 12 HBM4 chips, he noted.

The new architecture has been named after American astronomer Vera Rubin, who made significant contributions to our understanding of dark matter in the universe and conducted pioneering work on galaxy rotation rates.

Notably, despite the fact that NVIDIA has just launched the new Blackwell platform, it appears that NVIDIA keeps accelerating its roadmap. According to the latest information announced by Jensen Huang, the Rubin GPU will become part of the R series products and is expected to go into mass production in the fourth quarter of 2025. The Rubin GPU and its corresponding platform are anticipated to be released in 2026, followed by the Ultra version in 2027. NVIDIA also confirmed that the Rubin GPU will use HBM4.

Per a report from global media outlet Wccftech, NVIDIA’s Rubin GPU is expected to adopt a 4x reticle design and utilize TSMC’s CoWoS-L packaging technology, along with the N3 process. Moreover, NVIDIA will use next-generation HBM4 DRAM to power its Rubin GPU.

According to Wccftech, currently, NVIDIA employs the fastest HBM3e in its B100 GPU, and it plans to update these chips with the HBM4 version when HBM4 solutions are produced in large quantities by the end of 2025.
