It’s Official; IBM Launches The 5nm GAAFET Chip With 30 Billion Transistors Per 50mm², 75% Power & 40% Performance Boost
..The time of FinFET is gone folks, and now its time to move forward to GAAFET..
Right now, it’s expected that both Samsung and TSMC will commence risk production for 7nm next year. It’s currently time for 10nm, but IBM really has upped the bar today. IBM claims that when 5nm GAAFET is compared to 10nm commercial chips, you’ll get a 40% performance boost or an amazing 75% power consumption reduction, at similar performance levels. These are some big claims folks, so expect some big changes just around the corner. .
This chip is aimed at Cell Phones and other portables. But, it indicates how close we are to 5nm. So, maybe jumping to 7nm (as I mentioned above) is not cutting edge.
The article does indicate that 5nm requires a different, more complicated 3 dimensional architecture to work. So, its not merely a matter of making things smaller.
