You can compare transistor count per mm^2 instead of nanometers.
- dragontamer 5y agoBut you compare power-efficiency by how efficient each transistor is. TSMC N5p is 10% more efficient and 5% higher clocks than TSMC N5. The same 5nm __BY THE SAME COMPANY__ can change 15.5% in just a year, as manufacturing issues are figured out. Making every transistor 10% less power and 5% more GHz across the entire chip, while keeping the same size, is a huge bonus that cannot be ignored. I don't know what magic these chip engineers are doing, but they're surely spending some supercomputer on brute forcing all sorts of shapes/sizes of transistors to find the best density/power/speed tradeoffs per transistor. This is part of the reason why Intel stuck with 14nm for so long. 14nm+++++++ kept increasing clock speeds, yields, and power efficiency (but not density), so it never really was "worth it" for Intel to switch to 10nm (which Intel had some customer silicon tapped out for years, but only at low clock speeds IIRC). It isn't until recently that Intel seems to have figured out the clock speed issue and has begun offering mainstream chips at 10nm.
