[citation][nom]danwat1234[/nom]Source please?So, is Intel's and AMD's 45nm, 32nm not really those values? What is a 'node' when talking about nm from transistor emitter to base distance or whatever? I thought it was the real value but I guess not, just marketing!? Maybe some of the logic has transistors that are larger than other logic components of the chip.Thanks[/citation]
It's not correct what he wrote. The TSMC 20nm process is a tape out which means it's a true bulk process but it's not a working silicon in the way that all the transistors are there and so on, and you can measure them but not at their intended working voltage and clock rated.
The Intel 22nm bulk trigate process is actually closer to 24nm in true bulk process because trigate/finfet technology requires larger spacing.
The intended process for 20nm manufacturing is FD-SOI, and all SOI processes are capable of roughly 40% closer spacing (a half-node leap) compared to Intel's bulk process.
For reference please check the latest AMD processors from Glo-Fo compared to Intel. The AMD processors packs transistors roughly 40% closer than Intel even though supposedly on the same 32nm process. AMD processors also have slightly lower power consumption per mm2 even though, as noted above, packing 40% more transistors per mm2 than Intel.
