IBM has done it, any Idea what we could achieve with that?

That's around 10 atoms. Amazing!

More bloat.

We can achiever that as soon as any marketing person gets on the job.

Their "nm" numbers are meaningless anymore. They just redefine what they measure to make numbers lower.

Transistor density may be a better metric.

Intel's 10nm node is about 100m transistors/mm2
TSMC's 10nm node is 52m transistors/mm2
and their 7nm node is 91m transistors/mm2

So Intel's 10nm node is denser that TSMC's 7nm node.

IBM's 2nm node is around 330m transistors/mm2

While nothing prevents us from using technology in a wise and efficient way, doing so doesn't seem to be our favorite indeed.

That said, I wonder how things like leakage, heat management and even reliabilty are handled at this density.

Is it ever anything other than channel width length?  This of course is a key property.

Are there any density specs on TSMC's new 1nm node?
