IBM just unveiled a sub-1 nanometer chip breakthrough.
That honestly wasnt on my bingo card.
Its new 0.7 nm / 7 angstrom technology uses a 3D "nanostack" transistor architecture to vertically stack and stagger transistors.
IBM says it can fit nearly 100 billion transistors onto a chip the size of a fingernail, almost 2x the density of its 2 nm chip from 2021.
• up to 50% more performance
• or 70% better energy efficiency
• 40% SRAM scaling for AI workloads
Important caveat: this is still research, not a chip shipping tomorrow. IBM says production could happen as early as the next 5 years.
