- IBM developed a new chip architecture integrating nearly 100 billion transistors at a density twice that of its previous generation.
- The technology, termed the 'world’s first sub-1 nanometer chip technology,' promises significant performance improvements and energy efficiency for AI data centers.
- IBM’s 'nanostack' architecture aims to achieve the computing benefits expected from theoretical sub-1nm chips without physically shrinking features below that limit.
- The chip is described as being built at the 0.7-nanometer node, labeled as the 7 angstrom node, but node numbers no longer directly correspond to physical dimensions.
- Historically, chip node names matched physical feature sizes, but modern processes like 3nm or 2nm are marketing terms, not literal measurements.
