1. NVIDIA Unveils "Rubin" R100 Architecture: The 1nm AI Milestone
Date: July 28, 2026
NVIDIA has officially announced the "Rubin" R100 GPU architecture, marking the industry's transition to 1nm--class process technology (via TSMC). Designed to power the next generation of AGI--scale models, the Rubin platform introduces HBM4 (High Bandwidth Memory 4) and a revolutionary "Optical NVLink" interconnect, delivering a 4x performance--per--watt improvement over the Blackwell architecture.
| Metric | Blackwell (B200) | Rubin (R100) |
|---|---|---|
| Process Node | 4nm (Custom) | 1nm--class |
| Memory Type | HBM3e | HBM4 |
| Interconnect Speed | 1.8 TB/s | 4.5 TB/s |
| Efficiency | 1x | 4x |
This launch is viewed by analysts as a strategic move to secure NVIDIA's dominance in the "Reasoning AI" era, where hardware--level optimization for latent logic processing is critical.
