Is this 7 nm node really older than raspberry pi 5's 16 nm node?

> Next up is TSMC’s 12 nm FFC manufacturing technology, which is an optimized version of the company’s CLN16FFC that is set to use 6T libraries (as opposed to 7.5T and 9T libraries) providing a 20% area reduction. Despite noticeably higher transistor density, the CLN12FFC is expected to also offer a 10% frequency improvement at the same power and complexity or a 25% power reduction at the same clock rate and complexity.

They optimised for density and power, not frequency. A lot of the benefit they're claiming comes just from this.
