Cerebras puts entire NVL72 rack on single wafer, bypasses networking bottleneck

Cerebras has developed a new system that places an entire NVL72 rack onto a single wafer. This innovative approach circumvents the traditional networking power bottleneck by routing around defects and maintaining all processing on-die. The company's technology aims to provide a more efficient solution for large-scale computing needs. AI
