I guess it's the same as LEDs.. watts/lumen.
- 0-_-0 7y agoApparently it's easier to do some hocuspocus and use nm than transition to Transistors per square micrometer. See this chart of how they relate: https://en.wikichip.org/wiki/File:5nm_densities.svg https://en.wikichip.org/wiki/File:5nm_densities.svg
- wtallis 7y agoOne extra complicating factor is that each process node will have several different transistor libraries that make different tradeoffs between density and power/frequency. So a smartphone SoC will tend to have a higher MT/mm^2 number than a server CPU or GPU.
- Symmetry 7y agoYeah, the difference is more or less a factor of 3. The node gives you a smallest transistor size but making some transistors bigger than others lets you reach higher frequencies.
