Nvidia announces its upcoming AI chip lineup, including Blackwell Ultra for 2025, Vera Rubin for 2026, and Rubin Ultra for 2027, promising significant performance improvements and addressing the growing demand for AI computing power.

Nvidia Unveils Next-Generation AI Chips at GTC 2025

At the GPU Technology Conference (GTC) 2025 in San Jose, California, Nvidia CEO Jensen Huang announced a series of groundbreaking AI-accelerating GPUs set to revolutionize the AI computing landscape over the coming years 12.

Blackwell Ultra: The Immediate Future

Scheduled for release in the second half of 2025, the Blackwell Ultra B300 represents Nvidia's next step in AI chip technology. Key features include:

  • Two GPUs delivering 15 petaflops of dense FP4 compute performance per chip
  • 1.1 exaflops of dense FP4 inference compute when configured in a full NVL72 rack
  • 288GB of HBM3e memory per GPU, up from 192GB in the current Blackwell B200 1

Nvidia is positioning the Blackwell Ultra as a significant upgrade, offering 1.5 times more FP4 inference power than its predecessor and dramatically speeding up "AI reasoning" 5.

Vera Rubin: The Next Leap Forward

Named after the famous astronomer, Vera Rubin is set for release in the second half of 2026. This GPU architecture boasts:

  • 50 petaflops of FP4 inference performance per chip
  • 3.6 exaflops of FP4 inference compute in a full NVL144 rack configuration
  • A custom Nvidia-designed CPU called Vera, featuring 88 custom ARM cores with 176 threads 15

Rubin Ultra: Pushing the Boundaries

Slated for the second half of 2027, Rubin Ultra represents a significant leap in AI computing power:

  • 100 petaflops of FP4 precision per chip
  • 15 exaflops of FP4 inference compute and 5 exaflops of FP8 training performance at the rack level
  • 1TB of HBM4e memory per GPU, with a complete rack containing 365TB of fast memory 15

Future Developments and Industry Impact

Huang briefly mentioned "Feynman," a next-generation GPU architecture named after physicist Richard Feynman, expected to arrive in 2028 15.

The announcements come at a crucial time for Nvidia, as the company faces challenges including:

  • Reported overheating issues with early Blackwell cards
  • U.S. export controls and fears of tariffs affecting stock prices
  • Competition from Chinese AI labs developing efficient models 2

Despite these challenges, Nvidia remains optimistic about the future of AI. Huang envisions data centers as "AI factories" producing tokens instead of physical objects and speculates that Nvidia chips will soon power "10 billion digital agents" performing helpful work for humans 1.

Industry Implications and Market Position

Nvidia's announcements reinforce its dominant position in the GPU market, where it currently holds an estimated 82% share 2. The company's focus on increasingly powerful AI chips aligns with the growing demand for AI computing resources across various industries.

As AI applications continue to evolve and expand beyond the tech industry, Nvidia's new chip lineup positions the company to meet the increasing computational requirements of advanced AI models and applications 25.
