IBM claims nearly 100B transistors on a fingernail chip using “nanostack” tech that mimics below-1nm limits.
The milestone is real, but the bigger story is what it signals about who controls the next manufacturing playbook.
A new vertically stacked chip architecture could deliver up to 50% more work and 70% better energy efficiency in data centers.
