NVIDIA has once again raised the bar in artificial intelligence computing. At GTC 2025, the company unveiled the NVIDIA Vera Rubin Superchip, a groundbreaking platform combining an 88-core ARM-based CPU (“Vera”) and two next-generation “Rubin” GPUs. This powerful system-on-board design is built to redefine how AI data centers process, train, and deploy large-scale models — with up to 100 PFLOPS of AI compute in a single package.
What Is the NVIDIA Vera Rubin Superchip?
The Vera Rubin Superchip is NVIDIA’s next step after the Blackwell architecture, designed to deliver massive computational performance for AI training, inference, and HPC workloads. Unlike traditional systems that connect separate CPUs and GPUs, the Vera Rubin Superchip integrates them directly through ultra-fast NVLink-C2C interconnects, achieving over 1.8 TB/s bandwidth.
Each Superchip combines:
- 1× Vera CPU – 88 custom ARMv9 cores with 176 threads
- 2× Rubin GPUs – each with dual compute dies and 8 HBM4 memory stacks
- HBM4 memory – up to 192 GB per GPU for lightning-fast data access
- SOCAMM modules – LPDDR memory for CPU operations
This integration makes the Vera Rubin platform an “AI system on a board,” capable of unprecedented compute density and efficiency.

Performance and Capabilities
The Vera Rubin Superchip delivers massive efficiency gains for generative AI and LLMs. By leveraging FP4 (4-bit floating point) precision, NVIDIA enables faster inference speeds with lower power usage — ideal for serving complex models at scale.
When scaled up in server configurations like NVIDIA’s NVL144 systems, these chips can reach 3.6 exaFLOPS of FP4 AI performance, pushing the boundaries of what’s possible in AI computation.
This advancement aligns perfectly with NVIDIA’s ongoing dominance in AI infrastructure — powering everything from ChatGPT-like systems to autonomous driving and robotics.
Why the Name “Vera Rubin”?
NVIDIA named the chip after Vera Rubin, the pioneering astronomer whose work on dark matter transformed our understanding of the universe. It’s a fitting tribute, as the Superchip is designed to illuminate new frontiers in AI — much like Rubin’s discoveries expanded our cosmic horizons.
Market Impact
The Vera Rubin Superchip is not just a technical marvel; it’s a strategic weapon.
- For cloud providers: Expect denser, more efficient AI clusters with lower total cost of ownership.
- For enterprises: Faster training times for large language models and data analytics.
- For NVIDIA: Strengthened dominance in the AI chip market, putting more distance between it and competitors like AMD and Intel.
As AI adoption skyrockets, this chip will likely become the heart of next-generation data centers worldwide.
