IBM’s 0.7nm Nanostack Chip Design Could Push Semiconductor Scaling Into 3D
IBM has unveiled a new 0.7nm class chip technology that could reshape how future processors are built. The company says its Nanostack design can place nearly 100 billion transistors on a chip roughly the size of a fingernail, while offering up to 50% higher performance or 70% better energy efficiency than its earlier 2nm research technology. The announcement is important because chipmakers are reaching
