NVIDIA Rubin AI Chips: The New Leader In The Race For AI Dominance If accurate, these advanced processors could start leaving TSMC’s fabs by late 2025—this represents one of the fastest product cycles ever observed on the AI hardware scene.
The Rubin AI architecture: a redesign from the ground up
This is a complete overhaul of NVIDIA’s Rubin AI Chips. Rubin reportedly combines non-N3 CPU and GPU, which is still based on TSMC’s advanced N3P and N3B processes, with CoWoS-L packaging technology. It’s a small milestone in chiplet-based design, one NVIDIA is convinced will give its AI dominance an insurance policy for decades to come.
Included in the Vera Rubin platform will be:
- N3P+ N3B processes for CPU cores.
- On-die I/O to N5B supporting next-gen interconnects.
- 12-Integration of Hi HBM4 memory via CoWoS-m packaging
- Whole chiplet for CPU and GPU architecture.
It will be the first NVIDIA-ARM Chiplet designed CPU and will also use the latest approach the company has taken to modular scalability.
TSMC’s Role in Rubin AI Chips
All stages from semiconductors to packaging and chiplet integration of the NVIDIA Rubin AI Chips are manufactured by TSMC. According to analyst reports, at least six of the Rubin variants already exist in tape-out, and the tape-out may deliver fully functional chips by the end of the year.
That is to say, NVIDIA is outpacing any competitor. Blackwell Ultra GB300 production has only just ramped up, and yet the company is already gearing up for Rubin — a transition window of just six months between architectures.
Market Impact and AI Growth
Following the graphics giant’s Q2 earnings, CEO Jensen Huang made a daring claim: the AI compute sector could become a $3 trillion to $4 trillion market globally. NVIDIA has no competition left as Rubin AI chips are poised to power the next emergence of AI server and high-performance computing clusters.
Demand may soon come close to what NVIDIA experienced during previous transitions — like promising customers Ampere or Hopper — though with Rubin at the helm, perhaps even more so.
Why Rubin AI Chips Matter
The Rubin architecture is not just a performance improvement:
- Industry-first NVIDIA-ARM chiplet CPUs.
- Higher bandwidth memory (HBM4) adoption.
- Supports massive scalability for data centers and AI workloads.
- Competetive positioning vs AMD & Intel.
Through these innovations, it could also allow Rubin to re-imagine the boundaries of large scale AI training and inference.
