A 7nm tudjuk milyen.
Ámbátor Abu elmondása szerint a finfet a végét járja és egy új node kitapasztalásához több évre, több generációra, több iterációra van szükség, mint a finfet hajnalán volt.

5nm
"Now, TSMC is readying its new 5nm process for the first half of 2020. TSMC’s 5nm technology is 15% faster with 30% lower power than 7nm. A second version of 5nm, due out next year, is 7% faster. Both versions also will use EUV."
"“The numbers N6 and N5 look pretty close, but they still have a big gap,” said C. C. Wei, chief executive of TSMC, in a recent conference call. “For N5 compared with N7, the logic density increased by 80%. N6 compared with N7 is only 18%. So you can see there’s a big difference in that logic density and transistor performance."
3nm
"“Transistor costs at 3nm are expected to be 20% to 25% higher than at 5nm based on same level of maturity,” IBS’ Jones said. “Expect 15% more performance and with 25% less power consumption compared to 5nm finFETs.”"

Itt a táblázatokból a MTx/mm2 értéket érdemes megnézni:

Találgatunk, aztán majd úgyis kiderül..
